东北地区柔性基层配合比试验研究

Test Study of Flexible Base Mixture in Northeast Area

以吉林省境内长春至双辽高速公路为依托,针对寒区路面存在的严重反射裂纹病害问题,设计了大量的室内柔性基层配合比试验方案,结合试验结果比选出适合本地区柔性基层的最佳目标配合比及生产配合比,并通过现场试验进一步验证了配比方案的可行性.这一配合比方案的最终确定,可有效的减少路面反射裂纹病害的发生,对于指导东北地区柔性基层施工有重要的意义.

In this paper, the highway between Changchun and Shuangliao in Jilin Province is taken as the exam-ple for the existence of the problem in cold regions where pavement cracks. A lot of interior designs with flexible base ratio were carried out and the optimal program for the region was further verified by the field test. This pro-gram can effectively reduce the occurrence of disease of pavement reflection cracking, which is significant to the flexible base construction in Northeast China.
