Abstract: The asphalt paving industry has been increasing the use of recycled asphalt pavement (RAP). There is a concern about the percentage of aged asphalt binder in the RAP that can actually be blended into the virgin binder and ...

Abstract: With the continuing increase in the use of recycled asphalt pavement (RAP) and recycled asphalt shingle (RAS) for highway construction, there is a concern over how much of the aged asphalt binder inside RAP/RAS can be ...

Abstract: Styrene-butadiene-styrene (SBS) modified asphalt has been used in many road projects for its good performance at high and low temperatures. However, there was no final conclusion whether SBS could change the chemical ...

Abstract: This study aims to evaluate the effect of microwave radiation on the self-healing performance of asphalt mixture. Fracture-healing-fracture test was conducted via semicircular bending (SCB) test and microwave heating. The ...

Abstract: This work investigated the effects of the aging process on the performance of asphalt binder under multiple environmental conditions based on multitechnique experimental results. The aging process of matrix asphalt binder ...

Abstract: The application of photocatalysts on pavement engineering to degrade automobile exhaust has become a hot topic for researchers. However, the effect of photocatalysts on pavement materials has not been fully investigated. ...

Abstract: The modified boiling test based on image processing has gained significant attention in recent years, aimed at replacing subjective visual observation with an objective measurement. However, there are still some unsolved ...

Abstract: Research on the aging process of styrene-butadiene-styrene block copolymers (SBS) block copolymers modifier has practical significance in guiding the recycling of SBS-modified asphalt pavement. The objective of this study ...
