市政道路沥青混凝土路面使用性能评价研究

Study on Performance Evaluation of Asphalt Concrete Pavement of Municipal Road

为了研究城市道路中沥青混凝土路面使用性能的影响因素、评价方法及防治措施,对实际工程进行实地调研,应用层次分析法进行了分析。结果表明:影响市政道路沥青混凝土路面使用性能的因素有自然因素和人为因素;适用于市政沥青混凝土路面使用性能评价的11个指标为日最大降雨量、温度、交通量、超载情况、排水现状、周边施工情况、路面位置、既有病害情况、设计水平、路面施工质量、道路已服役年数。市政道路沥青路面使用性能宜划分为3个等级:Ⅰ级、Ⅱ级、Ⅲ级,且不同等级应采用不同的养护对策。

In order to study the influence factors, evaluation methods and preventive measures of the asphalt concrete pavement performance of urban road, the practical engineering is studied and analyzed by the analytic hierarchy process. The results show that factors affecting the asphalt concrete pavement performance of municipal road are the natural factors and human factors. 11 indicators suitable for the performance evaluation of municipal asphalt concrete road pavement are is daily maximum rainfall, temperature, traffic volume, overload, drainage status, surrounding construction situation, pavement location, existing disease,design level, pavement construction quality and road service years. The pavement performance of municipal asphalt road is suitably to divide into three grades: Grade I, II and III, and the different maintenance countermeasures are taken for the different grades.
