摘要
为研究沥青路面冷铺型预防养护技术,依托实际工程,对预防养护技术中的同步碎石封层技术进行分析,通过同步碎石磨耗试验得到湿轮磨耗值随着沥青洒布量的增大而减小,同步碎石封层最佳沥青洒布量取决于磨耗值稳定时的沥青洒布量。
In order to study the preventive maintenance technology of cold paving asphalt pavement,the synchronous macadam sealing technology in the preventive maintenance technology was analyzed based on the practical project.Through the synchronous macadam wear test,the wet-wheel wear value decreased with the increase of asphalt spreading amount,and the optimal asphalt spreading amount of synchronous macadam sealingdepends on theasphalt spreading amount when thewear value is stable.
