摘要
半刚性基层沥青路面反射裂缝一直是困扰工程建设的主要问题之一。基于路面长期性能跟踪观测(LTPP)理念,在对目前公路工程建设中常用的抗裂技术特性分析的基础上,以外部环境特征条件相近的实体工程为研究对象,进行针对性的半刚性基层沥青路面抗裂试验路段设计,并通过长期性能跟踪观测方案设计及性能检测,对各抗裂试验段进行了跟踪效果评估,研究比选了性能优异的半刚性基层抗裂技术,可为类似工程建设提供参考和借鉴。
Reflection crack is one of the mean diseases of semi-rigid base pavement. Based on the LTPP concept and the analysis of common anti-crack measures, this paper designs several anti-crack measures test sections, which are in the similar condition. With the long-term performance observation and performance test, the research evaluates the effects and application of each anti-crack measures, which can provide references for similar engineering construction.
