Investigation on the Performance and Modification Mechanism of High-Modulus Asphalt Binder: Effect of Micronized Composite Modifier Agent

High-modulus asphalt binders (HMABs) are critical for heavy-duty pavements but are often constrained by low-temperature brittleness and poor dispersion of conventional granular modifiers. This study develops a novel micro-pulverized composite modifier (ZY) integrating hard asphalt, an ethylene–propylene copolymer, and...
