Asphalt plastomer pellets

Asphalt is a widely used material for construction, especially for roads and roofs. However, unmodified bitumen does not have all the necessary physical properties for effective use. For example, unmodified asphalt can show poor performance grade ratings (PG ratings) when used as road pavement material.

To clarify, the PG rating measures the average highest temperature over seven days and the lowest temperature in one day for pavement design. Specifically, the highest temperature is measured 20 mm below the surface, while the lowest is measured at the surface. Although PG ratings can vary widely, asphalt typically used in road applications has ratings around 64-22. This means it can handle an average high of 64°C and a low of -22°C.

To improve asphalt performance, it is essential to use asphalt plastomer. In particular, you can add it to the modified asphalt mixture at about 5% by weight.

Using Asphalt Plastomer Pellets

Furthermore, you can also include a crosslinking agent in the modified asphalt mix. Not only does this addition effectively increase the gilsonite of the binders, which is crucial for performance, but it also lowers the phase angle of the binders, improving stability. Additionally, it significantly reduces the separation of the binders, which enhances the overall strength and lifespan of the asphalt mix.

In summary, by adding asphalt plastomer and a crosslinking agent, you can greatly enhance the performance of asphalt. Thus, this method makes asphalt a more dependable material for various construction projects. Ultimately, these improvements lead to better durability and functionality in road pavement and roofing.

Specification of Asphalt Plastomer Pellets

The asphalt plastomer pellets come with a range of beneficial properties that make them an ideal choice for enhancing asphalt mixtures. Furthermore, they provide a significant boost to the mechanical strength and durability of the final product. Below is a detailed specification to help you understand their features better:

  • Color: The pellets are black, which, in addition to blending seamlessly with standard asphalt, also contributes to their versatility across various applications.

  • Form: The material is in granular form, making it exceptionally easy to mix into asphalt. Additionally, this form factor ensures uniform distribution throughout the mixture, thereby enhancing the consistency of the end product.

  • Hardness: With a Shore A hardness range of 68-72, these pellets offer a balance of rigidity and flexibility, thus making them suitable for road surfaces subjected to different stress levels.

  • Density: The density stands at 1.53 g/cm³, indicating a compact and durable composition. Moreover, this density helps to maintain the structural integrity of the asphalt under varying traffic loads.

  • Tensile Strength: The pellets boast a tensile strength of 7 MPa, which significantly improves the overall strength of the asphalt. Consequently, it increases the road’s resistance to cracking and deformation.

  • Elongation at Break: With an elongation of 200%, the material offers substantial flexibility. As a result, it allows for better absorption of stress, especially in regions experiencing temperature fluctuations.

In conclusion, these asphalt plastomer pellets not only meet the stringent requirements for road construction but also provide enhanced performance, thanks to their comprehensive set of features.
