The ultraviolet (UV) aging of asphalt is an important factor affecting the long-term
performance of asphalt pavement, especially in high altitude cold regions. The current …

It has been confirmed that polyphosphoric acid (PPA) can significantly improve the high‐
temperature resistance, storage stability, and aging resistance of asphalt. The low price of …

Styrene Butadiene Styrene (SBS) polymer-modified asphalt binders have become widely
used in asphalt pavement because of their advantages in high-and low-temperature …

In order to investigate the effect of polyurethane (PU) modifier on the anti-UV aging ability of
asphalt, in this study, the base asphalt and PU modified asphalts were subjected to short …

High viscosity is an important feature of SBS modified asphalt, but it is not always favorable
because it need more energy to achieve the same viscosity for mixing and construction …

Styrene butadiene styrene (SBS)-modified asphalt ages prematurely in high-altitude
regions, affecting the durability of asphalt pavement. To improve the anti-ageing properties …

In order to study the effect of UV aging on asphalt performance, the asphalt four‐component
test, dynamic shear rheology test, and flexural creep stiffness test were combined with …

In order to investigate the effect of nano polymer materials on the UV aged performance of
asphalt binder, a nano PA modifying agent was selected to prepare modified asphalt. Under …

This study aimed to comprehensively enhance the antiaging performance of SBS-modified
asphalt (SBSMA) and make it available for long-life applications. UV absorbent (UV-531) …

The service life of polymer modified asphalt strongly depends on its weather resistance
because of its exposure to the natural environment. Three most widely used rubber modified …
