基于路面性能预测的路面养护规划与实施

Pavement Maintenance Plan and Practice Based on Pavement Performance Prediction

良好的预防性养护方案,可以以最优的成本提高路面的使用性能。因此,提出了一种兼顾路面性能衰变与养护费用的路面养护方案,并结合当年路面每个路段的实际技术状况,对未来几年的路面技术状况进行了预测;再根据预测结果以及养护经费情况,对路段养护优先级进行了划分;最终制定了各路段未来的养护方案,并跟进了养护方案的实施。该养护方案有效地提高了路面技术状况水平和使用性能。

A good preventive maintenance scheme can improve the performance of the pavement at the optimal cost.Therefore,a pavement maintenance scheme was proposed based on pavement performance decay and maintenance costs.Combined with the actual technical conditions of each pavement section in that year,those in the next few years were predicted;according to the prediction results and maintenance costs,the pavement maintenance priority were decided;finally,future maintenance schemes were carried out and the maintenance schemes were followed up.The scheme improved effectively the pavement level and performance.
