Implication

Simulation study reveals delayed cracking and reduced property loss in polymer and crumb rubber modified asphalt, indicating enhanced resistance to ultraviolet aging.

Key Points

Surface cracking emerges later and crack development progresses more slowly in polymer and crumb rubber modified asphalt under ultraviolet aging.
Indoor aging simulation evaluates penetration, dynamic stability, and freeze-thaw splitting strength across asphalt binders and mixtures during exposure.
Incorporation of rubber powder delays ultraviolet aging by moderating increases in large molecular weight and stabilizing functional group index changes.
