沪宁高速公路沥青路面使用性能预测

Use Performance Forecast of Asphalt Pavement on Hu-Ning Expressway

简要介绍了沥青路面使用性能评价的常用指数,考虑路面的多种失效模式,引用失效分析对沥青路面的损坏进行评价.以沪宁高速为例进行了分析,先用历年的路面强度指数SSI对路面综合指数PQI进行核对,然后再用路面无损检测所得的结果进行核对,其结果基本上符合实际情况.

Common indexes used to evaluate performance of asphalt pavement are briefly introduced. Considering various failure modes of pavement, failure analysis is adopted to evaluate the damage of asphalt pavement. Taking Hu-Ning expressway as an example, pavement quality index(PQI) is matched by means of annual structure strength index(SSI)and the detection result.The result is well in accord with the fact.
