specifikace bitumenu 6070

Why specification of Bitumen 60/70 is important?

Bitumen 60/70 one of the most commonly used grades of bitumen in road construction and industrial applications. Specification is important since Its widespread use stems from its optimal balance between hardness and flexibility, making it a favorite choice for asphalt pavements that must endure heavy traffic and diverse climatic conditions. This guide will take you deep into the physical and chemical attributes of Bitumen 60/70, its production methods, testing procedures, and much more. So, buckle up as we dive into the sticky but fascinating world of this crucial construction material.

Úvod do Bitumenu 60/70

The Bitumen 60/70 is a penetration-grade bitumen that refers to its hardness level. The numbers 60 and 70 indicate the range of penetration depth (measured in tenths of a millimeter) a standard needle can reach when pressed into the bitumen under specific conditions. A penetration value between 60 and 70 means this bitumen has a medium hardness and is neither too soft nor too brittle.

Bitumen itself is a viscous, black, and sticky substance derived from crude oil distillation. It’s primarily used for binding aggregates in road construction, but its role goes beyond roads—reaching into waterproofing, roofing, and even industrial manufacturing. Bitumen 60/70 stands out due to its versatility and performance under varying temperatures.

Its physical appearance is black and shiny, but the real magic lies in how it behaves under load and temperature shifts. Whether it’s blazing hot or freezing cold, this grade of bitumen maintains its structural integrity, which is why it’s so heavily preferred in temperate and subtropical regions.

Importance of Bitumen in Construction

Our Bitumen is literally the glue that holds roads together. In construction, it acts as a binder mixed with aggregate to form asphalt. Without bitumen, roads would crumble under the stress of daily traffic, water infiltration, and changing weather.

Besides roads, bitumen plays a huge role in waterproofing structures, protecting foundations, and even in soundproofing. Bitumen 60/70, in particular, is crucial because of its ability to perform well in medium-temperature environments, making it a globally traded product.

Its flexibility, cost-effectiveness, and durability make it irreplaceable in most modern-day construction projects. Whether it’s a rural road in a developing country or a busy expressway in a metropolis, Bitumen 60/70 is likely under your wheels.

Physical Properties of Bitumen 60/70

Hodnota penetrace

The penetration value is a key metric that defines the hardness of bitumen. For Bitumen 60/70, this value ranges from 60 to 70 deci-millimeters. This means a needle under a load of 100 grams for 5 seconds at 25°C will penetrate between 6 and 7 millimeters into the bitumen.

This test helps engineers understand how soft or hard the bitumen will be in real-world applications. A higher penetration value means a softer material, which is ideal for colder climates. A lower penetration means a harder bitumen, better for hotter climates. Bitumen 60/70 offers a balanced hardness, making it suitable for a wide range of conditions.

This range of penetration ensures the bitumen has enough resistance to deformation under heavy traffic and yet is flexible enough to avoid cracking in low temperatures. That’s why road builders often pick this grade—it’s the Goldilocks zone of bitumen hardness.

Bod měknutí

Another critical physical property is the softening point, usually measured using the Ring and Ball test. For Bitumen 60/70, the softening point lies between 46°C and 54°C. This tells us the temperature at which the bitumen transitions from a semi-solid to a viscous liquid.

Why does this matter? Imagine a road in a hot region—if the bitumen softens too early, it can lead to rutting and deformation. Bitumen 60/70’s softening point ensures that roads remain stable even during the hottest days of summer.

The Ring and Ball test involves heating a sample of bitumen and observing the temperature at which a steel ball drops through it. The precise measurements make this a trusted method to determine if a particular batch of bitumen will withstand the environmental conditions it’s meant for.

Kujnost

Ductility is the measure of a material’s ability to deform under tensile stress. For Bitumen 60/70, this value should be more than 100 cm. That means the bitumen can stretch over a meter without snapping—a key property when considering expansion and contraction due to temperature changes.

Why is ductility important? Because roads expand and contract all the time. Bitumen that can stretch without breaking helps avoid cracks, potholes, and overall structural failure.

To test this, a sample is pulled apart in a ductilometer until it breaks, and the distance stretched is recorded. High ductility ensures the bitumen can absorb the stress from moving traffic and thermal changes without giving way.

Chemické složení bitumenu 60/70

Hydrocarbon Structure

So far Bitumen 60/70 is composed predominantly of complex hydrocarbons. Around 95% of its content is hydrocarbons, while the remaining 5% consists of sulfur, oxygen, nitrogen, and trace metals. These hydrocarbons are classified into four main groups:

  • Asphaltenes: Provide rigidity and stiffness.

  • Resins: Offer bonding characteristics.

  • Aromatics: Contribute to fluidity.

  • Saturates: Add to the flexibility.

The balance among these four determines how the bitumen behaves under stress, heat, and pressure. Bitumen 60/70 offers a well-balanced mix, making it durable and flexible.

The carbon-to-hydrogen ratio and the molecular weight of the compounds within bitumen can significantly influence its performance. Engineers and chemists study these components in labs to ensure the batch meets regulatory and project-specific standards.

Additives and Impurities

While bitumen is primarily hydrocarbon, certain additives are introduced to improve its performance. These include:

  • Anti-stripping agents: To enhance adhesion with aggregates.

  • Polymers: For increased elasticity and temperature resistance.

  • Fibers: To improve strength and durability.

However, bitumen can also contain impurities like water, dust, or other residues from the refining process. These impurities can negatively impact performance, which is why stringent quality control tests are a must.

Výrobní proces bitumenu 60/70

Rafinace ropy

Lastly Bitumen 60/70 is primarily obtained through the distillation of crude oil in refineries. The process begins with the heating of crude oil to high temperatures in a distillation column, where lighter hydrocarbons such as gasoline, diesel, and kerosene are separated and collected from the top. What remains at the bottom is a heavy residue known as vacuum residue.

This vacuum residue is further processed to extract bitumen. The separation occurs in two main stages:

  1. Atmospheric Distillation: This removes the lightest fractions like gas and naphtha.

  2. Vacuum Distillation: Operated under reduced pressure, this extracts heavier fractions, leaving behind bitumen.

Bitumen derived through this method is called straight-run bitumen. It typically has excellent waterproofing and adhesive properties, and is often used directly or modified depending on its final application.

The key here is that no chemical additives are required in this stage; the bitumen’s composition is dictated by the crude oil source and refining technique. The refining process ensures the bitumen reaches the proper viscosity and penetration index necessary for its classification as 60/70 grade.

Air Blowing Method

In some cases, especially when bitumen needs to be harder or more heat-resistant, it undergoes air blowing. This process involves passing air through the vacuum residue at elevated temperatures (around 230°C–260°C). The air reacts with the hydrocarbons, causing oxidation and polymerization. This alters the bitumen’s structure, increasing its softening point and reducing its penetration value.

The air-blown bitumen often has enhanced performance characteristics such as increased resistance to water damage and better aging properties. However, care must be taken to control the process tightly, as excessive air-blowing can lead to brittleness.

For Bitumen 60/70, air blowing is only applied when the original distillation product doesn’t meet specification. Most refineries aim to produce 60/70 grade bitumen through precise control of distillation conditions without the need for further modification.

Technical Specifications of Bitumen 60/70

Normy ASTM

ASTM (American Society for Testing and Materials) is a globally recognized authority in setting technical standards for materials, including bitumen. For Bitumen 60/70, ASTM D946 and D5 are the key standards.

Here are the main technical specifications as per ASTM:

Měrná hmotnost při 25°C ASTM D70 - Cca. 1.01
Ztráta na vytápění ASTM D6 % ztráty hmotnosti
 

These specifications ensure consistency, quality, and safety for applications, especially in critical infrastructures like highways, bridges, and tunnels.

ISO and AASHTO Specifications

In addition to ASTM, Bitumen 60/70 also adheres to ISO (International Organization for Standardization) and AASHTO (American Association of State Highway and Transportation Officials) standards. These standards ensure the bitumen meets international requirements, making it suitable for use in global projects.

ISO 2909 and ISO 7346 outline test methods for viscosity, penetration, and other critical parameters. AASHTO specifications often mirror ASTM but with minor regional adjustments tailored to North American climates and road conditions.

By conforming to these standards, Bitumen 60/70 maintains its position as a globally accepted and traded product. This is especially important for contractors and engineers working on international projects where regulatory compliance is non-negotiable.

Aplikace bitumenu 60/70

Stavba silnic

High quality Bitumen 60/70 is most famous for its role in asphalt concrete used for road surfaces. Its balanced hardness makes it ideal for various climatic conditions—soft enough to flex under traffic loads and cold temperatures, yet hard enough to resist rutting and deformation during hot weather.

In road construction, it’s used in:

  • Surface layers of highways and expressways

  • Binder courses that support surface layers

  • Base layers in multilayer pavement structures

Its excellent binding capabilities ensure aggregates stay intact, reducing the risk of potholes and surface wear. Contractors often prefer Bitumen 60/70 because it provides long-term performance and reduces the need for frequent maintenance.

Moreover, its use isn’t just limited to highways. You’ll find it in residential roads, airport runways, parking lots, and industrial driveways. Its adaptability and availability make it a go-to choice across civil engineering projects.

Hydroizolace a střešní krytiny

Beyond roads, Bitumen 60/70 also plays a critical role in waterproofing solutions. Its natural water resistance and adhesive nature make it perfect for:

  • Flat roofs in residential and commercial buildings

  • Hydroizolace suterénu

  • Foundation coatings

  • Podzemní stavby

It can be applied as a hot mix or emulsified for cold application. In many countries, it’s blended with polymers or reinforced with fiberglass to improve tensile strength and longevity.

In roofing, it is often used in combination with felt or fibreglass sheets, forming a barrier that protects the structure from rain, moisture, and UV radiation. In regions prone to heavy rainfall or flooding, the bitumen’s sealing properties are a life-saver—literally keeping homes and buildings safe and dry.

Výhody bitumenu 60/70

Odolnost a flexibilita

One of the biggest reasons for the widespread use of Bitumen 60/70 is its incredible durability. Roads constructed with this grade of bitumen have a long life span, often exceeding a decade before needing major repair. This durability stems from the bitumen’s resistance to water, temperature extremes, and heavy traffic loads.

Quality Bitumen 60/70 is flexible enough to accommodate the expansion and contraction that comes with temperature changes. Unlike concrete, which can crack under stress, bitumen can stretch and bend slightly without breaking. This elasticity helps absorb vibrations from vehicles, which in turn reduces noise and wear over time.

It also handles the pressure of dynamic loads quite efficiently. Highways, for instance, see thousands of vehicles every day, many of them heavy trucks. Bitumen 60/70 provides a surface that can withstand this constant stress without falling apart. This makes it ideal for use not only in rural areas but also in heavily trafficked urban roads.

In addition to roads, its durability is highly valued in roofing applications. A properly installed bituminous membrane can last up to 20 years, effectively sealing out moisture and resisting environmental degradation.

Efektivita nákladů

Another undeniable benefit of Bitumen 60/70 is its affordability. Compared to other road-building and waterproofing materials, bitumen is much more budget-friendly. Not only is the initial material cost lower, but its long service life and minimal maintenance requirements offer excellent return on investment over time.

Since it is derived from crude oil—something most countries already import in large volumes—production costs are kept relatively stable. The refining process is also well-established, meaning there’s little need for costly new infrastructure.

Bitumen roads can be laid quickly, reducing labor costs and downtime. They are also easy to repair, often requiring only a localized patch rather than tearing up entire sections. These benefits make Bitumen 60/70 the top choice for governments, municipalities, and private contractors working within tight budgets.

Moreover, thanks to its recyclability, even worn-out asphalt can be reheated and reused, further cutting costs and reducing environmental impact. This economic edge is why developing nations in particular rely heavily on Bitumen 60/70 for infrastructure development.

Srovnání s jinými druhy bitumenu

Bitumen 80/100

Bitumen 80/100 is a softer grade compared to 60/70. The higher penetration value (80 to 100) means it’s less viscous and more pliable. This makes it ideal for colder regions, where the bitumen needs to remain flexible to resist cracking due to freezing temperatures.

However, its softness also means it’s less resistant to deformation under heavy loads, especially in hot climates. That’s why Bitumen 80/100 is rarely used in tropical or subtropical regions—it can rut easily under high temperatures and heavy traffic.

In terms of cost, both grades are relatively similar, but the choice depends on environmental conditions and traffic load. For example:

  • Bitumen 60/70 = Ideal for temperate and warmer climates.

  • Bitumen 80/100 = Better suited for cold, low-traffic regions.

When used inappropriately, 80/100 can lead to faster pavement failure, necessitating more frequent repairs and higher life-cycle costs.

Bitumen 40/50

On the other end of the spectrum, Bitumen 40/50 is a harder grade than 60/70. With a lower penetration value, it offers increased resistance to heat and load, making it suitable for extremely hot climates or high-load bearing surfaces like airport runways and industrial floors.

However, the trade-off is reduced flexibility. In colder temperatures, Bitumen 40/50 is more prone to cracking, which makes it less desirable for regions with seasonal weather variations.

This comparison can be summed up as follows:

Vlastnictví Bitumen 40/50 Bitumen 60/70 Bitumen 80/100
Hodnota penetrace 40-50 60-70 80-100
Flexibilita Nízké Střední Vysoký
Tvrdost Vysoký Střední Nízké
Nejlepší pro klima Hot Středně Studený
Traffic Load Suitability Těžký náklad Střední až vysoká Lehké zatížení

Choosing the right grade isn’t just a technical decision—it’s strategic. Selecting Bitumen 60/70 offers the best of both worlds for most climates and traffic conditions, which explains its dominance in global infrastructure projects.

Storage and Handling of Bitumen 60/70

Řízení teploty

Bitumen 60/70 is stored and transported in heated containers to maintain its workability. The ideal temperature for storage ranges from 140°C to 160°C, while the application temperature during road construction typically falls between 150°C and 180°C.

If the temperature exceeds 200°C, bitumen can start to degrade, altering its chemical composition and reducing performance. On the flip side, if it cools too much during transport, it can solidify, making it difficult to pump or mix with aggregates.

Maintaining the right temperature is crucial not just for ease of application but also to ensure that the bitumen retains its viscosity and adhesion properties. For long-distance transport, insulated tankers with heating systems are used. On-site, bitumen is kept in vertical storage tanks equipped with thermostats and circulation pumps.

Cold weather regions face the added challenge of reheating solidified bitumen. This is typically done using thermal oil systems or electric heating coils, which evenly warm the material without causing localized overheating.

Bezpečnostní opatření

Handling bitumen involves a number of safety hazards, mostly due to its high-temperature application. Workers must wear protective gear, including gloves, goggles, and heat-resistant clothing, to avoid burns from splashes.

Here are some essential safety guidelines:

  • Never expose bitumen to open flames. It is combustible and may emit harmful fumes.

  • Ventilation is key. During application, ensure there is enough airflow to disperse any volatile gases.

  • First-aid readiness. Emergency showers and eye-wash stations should be available at all handling sites.

  • Training. Only trained personnel should be involved in heating, transporting, and applying bitumen.

In addition, storage areas should be clearly labeled and restricted to authorized personnel. Spillage and leaks can be hazardous not only due to heat but also because they create slippery surfaces, posing fall risks.

By following standard safety protocols, contractors can ensure both the effective use of Bitumen 60/70 and the well-being of workers and the environment.

Testing Methods for Bitumen 60/70

Laboratorní testy

Before bitumen 60/70 can be used in large-scale construction, it must undergo rigorous testing in certified laboratories. These tests ensure the material meets industry standards and performs as expected under various environmental conditions and loads.

Here are the most commonly performed laboratory tests:

  1. Penetration Test (ASTM D5)
    This determines the hardness of bitumen by measuring the depth a standard needle penetrates under controlled conditions. For bitumen 60/70, acceptable values range between 60–70 deci-millimeters.

  2. Softening Point Test (Ring and Ball Method – ASTM D36)
    This evaluates the temperature at which bitumen softens enough to let a steel ball fall through it. A softening point between 46°C and 54°C is typical for bitumen 60/70.

  3. Ductility Test (ASTM D113)
    This test measures how much a bitumen sample can stretch before breaking. Bitumen 60/70 should have a ductility of over 100 cm.

  4. Flash and Fire Point Tests (ASTM D92)
    These assess the safety of bitumen by measuring the temperatures at which it emits flammable vapors (flash point) and catches fire (fire point). Bitumen 60/70 usually has a flash point above 232°C.

  5. Specific Gravity Test (ASTM D70)
    Determines the density of bitumen relative to water. This helps engineers calculate how much material is needed for a given volume of mix.

  6. Solubility Test (ASTM D2042)
    Ensures bitumen purity by checking how much of it dissolves in a solvent like trichloroethylene. Bitumen 60/70 should have more than 99% solubility.

These lab tests are essential for confirming the grade, quality, and usability of bitumen before it’s applied in real-world conditions. They also help in troubleshooting issues post-application by comparing field samples with original lab results.

Polní testy

While lab tests are more comprehensive, field tests are equally important to ensure quality control during actual road construction or waterproofing projects. These tests are quicker and provide real-time data to help engineers make immediate decisions.

Some essential field tests include:

  1. Viscosity Check (Brookfield or Saybolt Viscometer)
    Checks whether the bitumen is too thick or too runny for mixing with aggregates. Proper viscosity is key to ensuring good coverage and adhesion.

  2. Monitoring teploty
    Field teams regularly check the temperature of bitumen before mixing and laying. Overheating can damage the material, while underheating can affect the mix quality.

  3. Aggregate Coating Observation
    A quick visual check to confirm that the bitumen is properly coating the aggregates. Poor coating can lead to stripping and pavement failure.

  4. Compaction Quality Assessment
    Once the asphalt is laid, rollers compact it. Engineers inspect the compacted surface to ensure there are no air pockets or uneven sections.

Field testing acts as a real-time quality control mechanism, allowing any issues to be corrected immediately, rather than after the entire road or structure is completed.

Environmental Impact of Bitumen

Emissions During Production

Bitumen, like many petroleum products, has a notable environmental footprint. During production—especially in the distillation and air-blowing stages—volatile organic compounds (VOCs) and greenhouse gases (GHGs) are released into the atmosphere. These emissions contribute to air pollution and climate change.

Additionally, the process of heating bitumen for application releases fumes containing polycyclic aromatic hydrocarbons (PAHs), which can be harmful if inhaled over prolonged periods. That’s why many industrial sites are now required to install fume collection systems and implement emission control technologies.

Another environmental concern is the energy-intensive nature of bitumen production. From refining crude oil to transporting and heating the product, each stage consumes a significant amount of fossil fuel.

To address these issues, industry leaders are moving toward cleaner technologies such as:

  • Low-emission refining units

  • Cold mix bitumen alternatives

  • Emission filters and carbon offset practices

Udržitelné alternativy

In response to the environmental concerns associated with conventional bitumen, several sustainable alternatives are gaining popularity:

  1. Polymerem modifikovaný bitumen (PMB)

  2. Bio-Bitumen
    Derived from renewable resources like algae, lignin, and vegetable oils, bio-bitumen aims to replace petroleum-based products. While still in developmental phases, it’s showing promise as a greener alternative.

  3. Warm Mix Asphalt (WMA)
    Requires lower temperatures during mixing and laying, reducing fuel consumption and emissions. WMA technologies also allow for longer transport times and extended paving seasons.

  4. Recycled Asphalt Pavement (RAP)
    Using old asphalt materials in new road construction dramatically reduces the need for virgin materials, conserving natural resources and reducing landfill waste.

These innovations mark a turning point in the industry, proving that performance and sustainability can go hand-in-hand. Governments and environmental agencies are also beginning to incentivize the use of such eco-friendly solutions, setting the stage for widespread adoption.

Future Trends in Bitumen Technology

Polymerem modifikovaný bitumen

One of the most exciting advancements in the bitumen industry is the development and adoption of Polymer Modified Bitumen (PMB). This innovative material incorporates polymers into traditional bitumen to enhance its performance characteristics significantly. Polymers such as SBS (Styrene-Butadiene-Styrene) and APP (Atactic Polypropylene) are commonly used to increase elasticity, improve temperature susceptibility, and extend the service life of asphalt.

PMB offers several advantages over conventional Bitumen 60/70:

  • Superior Rutting Resistance: Roads remain stable even under heavy traffic and high temperatures.

  • Improved Fatigue Resistance: Withstands repetitive stress without cracking.

  • Enhanced Adhesion: Provides better bonding with aggregates, reducing stripping and water damage.

  • Wider Temperature Range: Performs well in both extremely cold and hot climates.

As infrastructure demands grow and climate change brings more extreme weather, PMB is quickly becoming the preferred choice for highway authorities and engineers. Countries like the U.S., Germany, and India are increasingly specifying PMB in national road projects for its durability and performance.

However, PMB does come at a higher initial cost. But when considering its long-term benefits and reduced maintenance, it often proves to be a more economical solution overall.

Ekologické inovace

As environmental consciousness increases globally, the bitumen industry is rapidly embracing eco-friendly innovations. Traditional bitumen, while effective, has a notable carbon footprint. New technologies and methods are being developed to counter this.

Key green innovations include:

  1. Warm Mix Asphalt (WMA)
    Unlike conventional hot mix asphalt, WMA can be produced and applied at lower temperatures (typically 30°C to 40°C lower). This significantly reduces fuel consumption and CO₂ emissions during production.

  2. Bio-Based Bitumen
    Derived from renewable sources like plant oils, lignin, and algae, bio-bitumen reduces dependence on petroleum. Though still under development, several pilot projects have shown positive results, especially in low-load applications.

  3. Recyklovaný asfalt
    Using reclaimed asphalt pavement (RAP) reduces the need for virgin materials and cuts down on landfill waste. Many modern roads are now built with up to 30–50% recycled content, helping governments meet sustainability targets.
