摘要
通过对大粒径沥青混合料 (L SAM)和普通密级配沥青混凝土进行的一系列路用性能试验研究 ,包括高温变形特性、低温抗裂性、水稳性和抗疲劳特性试验 ,结果表明大粒径沥青混合料具有优良的路用性能。经石黄高速公路上的试验路使用一年多的验证 ,结果也表明 L SAM具有良好的使用效果 ,可延长路面使用寿命 。
A series of tests are carried out to analyze the characteristics of high temperature rutting, low temperature crack resistance, water stability, fatigue resistance of large stone asphalt mixture (LSAM) and dense graded asphalt concrete. The results show that the pavement performance of LSAM is better than others. Finally the experimental section in Shi Huang Expressway is built on the basis of laboratory study, the application results show that its life is prolonged.
