摘要
通过对三种不同粗细的合成级配进行试验,对沥青混凝土工作性的影响进行比对,主要分析如何选择级配,找出矿料级配对公路沥青混凝土性能的影响程度,使最大密度线更好地满足其技术指标,从而达到延长路面使用寿命和车辆行驶的安全性的目的。
In this paper, through the experiment of three kinds of gradation of different thickness, compare the influence on workability of asphalt concrete, the paper analyzes how to choose the gradation, find out the influence degree of aggregate gradation on performance of asphalt concrete, so as to achieve the maximum density line to better meet the technical indicators.Thus, the purpose of prolonging the service life of the road and the safety of the vehicle running is achieved.
