RA抗车辙剂对沥青混合料高温性能的影响研究

Influence of RA Anti-Rut Agent on High Temperature Performance of Asphalt Mixture

车辙是沥青路面主要破坏形式之一,它严重影响了行车的安全性和舒适性。通过沥青胶浆DSR模量试验、车辙试验来研究RA抗车辙剂对沥青混合料高温性能的影响,并且与70#普通沥青、PRM改性沥青进行对比,结果表明:添加RA抗车辙剂能显著改善沥青胶浆及其混合料的高温性能。

Rut is one of main failure modes of asphalt pavement, which greatly influences the traveling safety and comfort. The paper studies the influence of RA anti-rut agent on high-temperature property of asphalt mixture through DSR test and rut test, and compares it with 70# ordinary asphalt and PRM asphalt. The results indicate that the RA anti-rut agent can obviously improve the high temperature performance of asphalt bindersand mixtures.
