328国道江阳段沥青路面使用性能评价及处治方案探讨

Pavement Performance Evaluation and Maintaining Methods of Jiangyang Section of Line G328

公路在交通荷载和自然环境的共同作用下,路面使用性能会随着时间的推移而日益衰减,从而直接影响车辆的行驶速度和运输的安全性、经济性和舒适性。为了评估和预测路面使用性能状况,便于进行科学的养护和管理,系统地提出公路沥青路面使用性能评价的指标体系和分级标准,并根据实测数据与规范推荐,选择合适的养护维修决策,可为路面养护提供参考。

Under long-term effect of traffic loads and environmental mance will debase with time, which has direct influence on driving economic implication. In order to evaluate and predict the present impacts the pavement perforsafety and comfort with the and future performance, some evaluation indexes which can reflect road conditions systematically are discussed and proposed. In the end, according to datum measured and criterion recommended, appropriate maintaining measures are collected, which can provide reference for pavement maintenance.
