摘  要:
以哈尔滨红旗大街道路工程为例.分析了二灰碎石作为路面基层的强度形成机理和路用性能.对提高二灰碎石基层早期强度的实际应用做了验证、在养生期和缩裂特性等方面与水泥稳定砂砾基层作了比较。竣工通车1a后的检测数据表明.二灰碎石基层的路表平均弯沉、基层顶面当量回弹模量及基层材料的无例限抗压强度等项指标均优于水泥稳定砂砾基层结构。

摘  要:
Taking Harbin Flag Big Street road for example. the strength forming reason and road :behavior ofthe two lime broken stones as the pavement basic level were analyzed. and the application of improvingits early strength was also tested. Meanwhile, it was compared with cement stabilized gravel stratum inshrinkage crack property and other respects. The detected data after drive-through for 1 year showedthat the index such as top surface equivalent rebound module of stratum and compression strengthti.ithout side-limit of stratum materials, etc. were all superior to those of cement stabilized gravel stratum.
