抗剥落剂对橡胶颗粒沥青混合料性能影响研究

the Effect of Anti Stripping Agent on Rubber Particle Asphalt Mixture Performance

采用消石灰、水泥及TOR连接剂等不同抗剥落剂制备橡胶沥青混合料,分析其对橡胶沥青混合料残留稳定度、冻融劈裂强度以及动稳定度的影响。结果表明:水泥、消石灰及TOR连接剂三种抗剥落剂均能改善橡胶颗粒沥青混合料的水稳定性和高温稳定性,改善效果排序为TOR>水泥>消石灰;TOR连接剂对橡胶颗粒沥青混合料高温性能提升约35%。

Slaked lime,cement and Trans-Polyoctenamer Rubber(TOR)bridging agent are selected as anti-stripping agents in prepare rubber asphalt mixture,and their effect on the stability,freezing-thaw splitting strength and dynamic stability of asphalt residue are analyzed.It was found that these three kinds of anti-stripping agents all better the water stability and high-temperature stability of mixture.And the performance rank is TOR>cement>slaked lime.The TOR could improve the high temperature performance of rubber particle asphalt mixture by about35%.
