Asphalt plastomer pellets
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.
