摘要
在研究沥青路面施工质量对沥青路面性能影响的基础上,对施工质量过程评价指标进行了分析筛选,选择质量缺陷百分率PD作为质量评价指数的基础上,给出了指数形式的沥青路面施工质量评价模型,进行沥青路面寿命预估,指数模型预测寿命为17.98年。该模型的建立对后期沥青路面的质量评价具有重要的指导意义。
On the basis of studying the influence of asphalt pavement construction quality on asphalt pavement performance, the construction quality process evaluation index was analyzed and screened. Based on the quality defect percentage PD as the quality evaluation index, the exponential form of asphalt pavement construction was given. The quality evaluation model is used to estimate the life of asphalt pavement, and the life expectancy of the exponential model is 17. 98 years. The establishment of this model has important guiding significance for the quality evaluation of asphalt pavement in the later stage.
