乌鲁木齐沥青混凝土路面典型病害调查及对策研究

Survey and Countermeasure Study on Typical Diseases of Asphalt Concrete Pavement in Urumqi

由于乌鲁木齐特殊的环境气候特征,寒暑季节温度变化剧烈、雨雪春融季节冻胀循环频繁,导致市区范围内沥青混凝土路面在使用过程中提前出现各类病害的现象较为普遍,通过对乌鲁木齐市沥青混凝土路面病害进行系统的调查分析,确定主要病害、分析产生原因,从项目管理、设计、施工、养护、材料特点、温度因素等方面提出相应对策,达到减少路面病害、延长道路使用时间的目的。

Owing to the special environmental climate features of Urumqi, the temperature changes sharply in cold and heat seasons, and the cycle of frost heave is frequent in the melting season of rain, snow and spring, which lead to that various diseases of asphalt concrete pavement appear more early and more generally in the service process. According to the systematically survey and analysis on the diseases of asphalt concrete pavement in Urumqi, the article determines the main diseases and analyzes the disease causes, and puts forward the relative countermeasures from the project management, design, construction,maintenance, material characteristics and temperature factors in order to reduce the pavement diseases and prolong the road use time.
