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。
A Case Study of Hongqi Street in Harbin. The strength formation mechanism and road performance of lime-fly ash as pavement base were analyzed. The practical application of improving the early strength of lime-flyash gravel basement was verified, and compared with the cement-stabilized gravel basement in terms of curing period and shrinkage cracking characteristics. After the completion of the opening of the test data show that 1a. The average surface deflection of lime-flyash gravel base, equivalent elastic modulus of base top surface and unconfined compressive strength of base material were all better than those of cement stabilized gravel basement.
