Effect of Various Metal Hydroxide Flame Retardants on the Rheological Properties of Asphalt Binder
Metal hydroxide has been widely used as flame retardant to reduce the hazards of tunnel fire, however, few researches investigate its effect on the rheological properties of asphalt binder systemically.

Crumb rubber modified asphalt (CRMA) offers several advantages such as increased rutting resistance and enhanced stability. However, few studies have explored the relation between CR size and rutting resistance of CRMA mixtures at different temperatures as well as the development of prediction models to assess the performance of CRMA mixtures ...

Rheo‐Chemical Characterization and ML‐Based Prediction of Rejuvenated RAP Binders
Reclaimed asphalt pavement (RAP) has gained significant attention in pavement engineering due to its economic and environmental benefits. However, the high stiffness and brittleness of aged RAP binders (RPB) necessitate the use of rejuvenators to restore their performance. This study evaluated the effectiveness of two commercial rejuvenators (PX and RB)

Conventional polymer modification of bitumen, while enhancing in‐service performance, often leads to increased material costs. Recycled tire‐derived crumb rubber (CR) presents a sustainable and economically viable alternative, offering valuable elastomeric properties and environmental benefits by diverting waste from landfills.

Estimating Optimum Compaction Level for Dense-Graded Hot-Mix Asphalt Mixtures
A critical step in the design of asphalt mixtures is laboratory compaction. Laboratory compaction should reflect field compaction and should produce mixtures that are economical and possess high structural stability.

This study addresses the critical limitation of inadequate crack resistance in high‐modulus asphalt mixtures by systematically investigating the efficacy of various modification strategies. A base asphalt mixture, and a styrene–butadiene–styrene (SBS)‐modified asphalt mixture were established as control references, while a standard high‐modulus ...
