辽宁省大粒径抗裂型水泥稳定碎石抗裂效果评价与分析

Evaluation and Analysis on Anti-cracking Effect of Large-size Anti-cracking Cement Stabilized Macadam in Liaoning Province

水泥稳定材料基层路面结构广泛应用于各等级公路,横向裂缝病害逐渐成为公路主要典型病害。根据不同地区六条大粒径抗裂型水泥稳定碎石基层试验路与常规水稳碎石基层对比段逐年观测结果,评价大粒径抗裂型水泥稳定碎石材料组成优化改善横向开裂的抗裂技术应用效果,总结了在辽宁省典型季冻区域,应用大粒径抗裂型水泥稳定碎石的经验。

The pavement structure of cement stabilized material base is widely used in various levels of highways,and the transverse crack disease gradually becomes the main typical disease of highway.According to the observation results of six test roads of large-size anti-cracking cement stabilized macadam base in different regions and the comparison section of conventional water stabilized macadam base year by year,the application effect of anti-cracking technology of large-size anti-cracking cement stabilized macadam material composition for optimizing and improving the transverse crack is evaluated,and the experience of applying large-size anti-cracking cement stabilized macadam is summarized by taking our province as a typical seasonal freezing area.
