摘要
高粘沥青是排水沥青混合料的核心材料。文中采用星型和线型SBS改性沥青制备高粘沥青,在此基础上,室内成型OGFC-13排水沥青混合料,并对沥青混合料的路用性能进行研究。通过往复车辙轮碾压试验、低温弯曲梁试验、冻融劈裂试验和浸水飞散试验进行对比。结果表明,采用星型SBS制备的排水沥青混合料各项路用性能均优于线型SBS排水沥青混合料。
Viscous asphalt is the core of the drainage asphalt mixture material.In this research,the high viscosity asphalt was produced using star-shaped and linear SBS respectively,on this basis,the pavement performance of OGFC-13 drainage asphalt mixture was tested in the laboratory.It was found that the pavement performance of asphalt mixture made by the star-shaped SBS was better than that made by the linear SBS through the wheel rutting test,beam bending test,freeze-thaw splitting test and water dispersion test.
