厚层水稳碎石压实度差异对路用性能影响研究

Effect of Compaction Differences on the Road Performance of Thick Layer of Cement Stabilized Macadam

通过模拟现场压实度差异的方法对厚层水泥稳定碎石基层结构抗压强度、劈裂强度和抗冲刷等路用性能进行了研究.结果表明:压实度对水泥稳定碎石的力学性能和耐久性能有明显影响,随着上下层平均压实度降低,厚层水泥稳定碎石的路用性能降低;在压实度降低幅值相同条件下,上层压实度越高,对应的路用性能降幅越小.

Based on field simulation test of compaction difference,the road performance（including compressive strength,cleavage strength and anti-erosion properties etc） of cement stabilized macadam was studied.Experimental results show that compactness has obvious effect on the mechanical property and lasting quality of cement stabilized macadam,the road performance of cement stabilized macadam reduce with the decrease of the average compaction between upper and lower layers;if the compaction reduce the same amplitude,the higher the compaction of the upper layer,the better road performance of the cement stabilized macadam base structure.
