沥青路面车辙形成因素的试验研究

Experimental Research on Causes for Asphalt Pavement Rut

根据室内不同车辙影响因素作用下的轮辙试验,对比分析了采用普通沥青混合料和改性沥青混合料的抵抗车辙性能,分别得到沥青混合料的动稳定度与不同交通荷载、温度、水、沥青、混合料组成之间的变化曲线,研究表明SBS改性沥青混合料的抵抗车辙能力要优于普通沥青混合料,同时确定了沥青混合料在不同交通荷载、温度、水、沥青、混合料组成作用下的变化规律。

In accordance with lab trial of wheel rut under different influencing factor, the paper analyzes by contrast the rut - resistances of adopted average concrete mixture and modified asphalt mixture, respectively getting the varying curves of the dymamic stability of asphalt mixture with the different traffic load, temp, water, asphalt and composed mixture. Researching results indicate that the average asphalt mixture is preceded by SBS modified asphalt in rut - resistance, simultaneously determixes the varying law of asphalt mixture under action of different load, temp, water, asphalt and mixture.
