Abstract

To investigate the effects of rubber powder’s distribution on the ductility of RA, the force-ductility test (FDT) was conducted with rubber contents of 15, 20, 25, and 30 wt%, and the results demonstrated that the dense rubber powder in RA will reduce its ductility. The microscopic tests discovered that the rubber powder distribution significantly impacted the mechanical performance of RA. Subsequently, based on the Monte Carlo method and Python, models of RA were established, and FDT was simulated from the mesoscopic view. The findings demonstrated that the dense distribution of rubber powder led to poor ductility of RA. Consequentially, this study offered an innovative mesoscopic perspective of studying RA, particularly the multiple impacts of rubber powder distribution on RA.

从中观角度评估和表征橡胶粉分布对橡胶沥青延展性的影响

为了研究橡胶粉分布对 RA 延展性的影响，在橡胶含量为 15、20、25 和 30 wt% 时进行了力-延展性试验（FDT），结果表明 RA 中致密的橡胶粉会降低其延展性。微观测试发现，橡胶粉的分布对 RA 的机械性能有很大影响。随后，基于蒙特卡罗方法和 Python，建立了 RA 模型，并从中观角度模拟了 FDT。研究结果表明，橡胶粉的密集分布导致 RA 的延展性较差。因此，该研究为研究 RA，尤其是橡胶粉分布对 RA 的多重影响提供了一个创新的中观视角。
