摘　　要：为了研究大孔隙基体沥青混合料的设计组成对灌注式沥青路面路用性能的影响,采用添加高粘剂和改变级配组成的方式来制备灌注式沥青混合料,并对其路用性能进行测试。结果表明,通过添加高粘剂可以提高灌注式沥青混合料的高温性能、低温性能和水稳定性能,而通过提高细集料的比例可以小幅提高其低温抗裂性,但会降低其高温抗变形性能,因此提高沥青粘结剂的性能是提高灌注式沥青混合料性能的有效措施。In order to study the influence of the design composition of macroporous matrix asphalt mixture on the pavement performance of cast-in-place asphalt pavement,the cast-in-place asphalt mixture is prepared by adding high viscosity agent and changing the gradation composition,and its pavement performance is tested.The results show that,the high temperature performance,low temperature performance and water stability of cast-in-place asphalt mixture can be improved by adding high viscosity agent,while the low temperature crack resistance can be slightly improved by increasing the proportion of fine aggregate,but the high temperature deformation resistance will be reduced.Therefore,improving the performance of asphalt binder is an effective measure to improve the performance of cast-in-place asphalt mixture.
