高模量沥青混合料的动态模量试验研究

高模量沥青混合料是通过在基质沥青中添加调和硬组分从而提高其模量的。实验对混合料进行了配合比设计,并对其与其它几种混合料在不同温度、不同加载频率条件下进行动态模量对比试验研究。结果显示高模量沥青混合料可以在不降低混合料低温性能的同时,有效提高其高温稳定性,抑制和减少车辙的产生,从而保证道路的良好使用性能。

Experimantal Research On Dynamic Modulus of Asphalt Mixture with High Modulus

The asphalt mixture with high modulus is formed through adding the hard constituent harmonious into the matrix asphalt.The proportioning design of the mixture was carried out.And there was performed the comparative experimental research-namely the proportionally designed mixture was compared to another several mixtures in the dynamic moduluses under different temp and loding frequency.Researched results show that the asphalt mixture with high modulus can effectively increase its stability at high temp,restrain and reduce the rut and guarantee a good service performance of road without lowering the low temp of the mixture.
