既有水泥混凝土路面的破坏模式及路面强度评价的试验分析

Experimental Analysis of Failure Modes and Pavement Strength Evaluation to Existing Cement Concrete Pavement

为了达到对黄石地区既有水泥混凝土路面强度进行评价的目的,分析了当前黄石地区大面积既有水泥混凝土路面破坏现状,基于正交试验法进行了试验方案的设计,运用回弹法和利用室内压力机进行了试验,同时借助数学方法对试验结果进行分析,最终建立既有水泥混凝土路面强度评价体系,为大面积的旧水泥混凝土路面的治理改造提供理论支持。

In order to evaluate pavement strength of existing cement concrete pavement in Huangshi, the paper analyzed failure modes of pavement based on investigating in situ. Test design for the main control factors of the cement concrete strength was executed on orthogonal test method. Rebound experiment and indoor pres-sure test were applied and mathematical methods were used to analyse test results. At last, the pavement strength evaluation system was put forward to existing cement concrete pavement. This will be useful to pro-vide theoretical support for rebuilding and improving the old cement concrete pavement in large scale.
