Abstract: Ultraviolet (UV) radiation causes asphalt aging and thus influences its performance. In this research, a composite light stabilizer was prepared to increase the light stability of matrix asphalt. Benzotriazole UV absorber ...

Abstract: In this study, cement-stabilized granite mill tailings were used as a subbase material in highway construction. The properties of the cement-stabilized mill tailings were evaluated through laboratory testing and compared ...

Abstract: Current gradation design in Superpave mix design method is an empirical-based trial-and-error method, which is costly and time-consuming. Moreover, few mechanical properties have been evaluated during the mix design to ...

Abstract: This research aims to evaluate the performance of flexible base asphalt pavement compared with traditional semirigid base asphalt pavement in practical application in central China under heavy load conditions. Four different ...

Abstract: This study aimed to explore the interaction and antiaging characteristics of composite phase change materials in asphalt for long-term temperature adjustment of asphalt pavement. First, the epoxy resin/phase change materials ...

Abstract: The performance of hot-asphalt mix (HMA) is significantly impacted by ultraviolet (UV) aging. While asphalt fine aggregate matrix (FAM) is a crucial component of HMA, its impact on the material’s performance during UV aging ...

Abstract: Laboratory tests were conducted to evaluate the feasibility of recycling phosphorus slag into hot-mix asphalt (HMA) as mineral fillers. The elemental composition of phosphorus slag was analyzed by energy dispersive ...

Abstract: The polymer curing agent was used in the slope and the external-soil grass-planting was then carried out. It was found that this new ecological protection technique can effectively prevent, weaken, or slow down the softening ...

Abstract: Aggregate occupies at least three-quarters of the volume of asphalt mixture and can significantly affect the performance of pavement. The geometrical morphology influences the slippage and interlock among aggregates for ...

Abstract: This paper researched the rheological properties of activated rubber powder–modified asphalt after aging. However, current aging methods only consider the aging of asphalt binder itself, ignoring the effect of asphalt ...
