沥青用量对沥青路面使用性能的影响

The Influence of Asphalt Consumption on Technical Characters of Asphalt Pavement

通过沥青混合料的马歇尔试验,研究沥青用量对沥青混合料以及沥青路面产生的影响.结果表明:沥青用量会显著影响其混合料的高温稳定性,低温抗裂性,抗滑性,施工和易性、耐久性等技术性质,进而影响沥青路面的使用性能.最佳沥青用量可改变沥青混合料的内部组成结构,改善沥青混合料的技术性质,提高沥青路面的使用品质,获得较好的经济性.

The influence of asphalt consumption on asphalt mixture and asphalt pavement was studied by conducting Marshall test of the mixture. The results indicated that asphalt consumption obviously affected the technical characters of asphalt mixture such as high temperature stability, low-temperature crack-resisting property, skid resistance, workability and durability, and consequently impacted the usage features of asphalt pavement. The optimum asphalt consumption could alter interior structure of asphalt mixture, improve technical characters of asphalt mixture, improve usage quality of asphalt pavement, and also obtain better economic property.
