摘要
通过对国道214线邦达机场至邦达运输站路段干线公路的实地调查和分析,总结了昌都地区沥青路面早期破损的主要形式,分析了病害发生的主要原因,提出了寒区道路采用LTC沥青再生养护剂的预防性养护施工工艺,并对比了养护前和养护后的效果。结果表明:LTC沥青再生养护剂可以延长路面的使用寿命,对提高路面使用质量、美化路面外观有重要作用。
The main forms of early damage of asphalt pavement in Qamdo were summarized through the field investigation and analysis of the section from Bangda airport to Bangda transportation station of National Highway 214. The main reasons for the occurrence of the disease were analyzed. The preventive maintenance with LTC, a regenerative curing agent for asphalt,and the construction technology of highways in the cold regions were put forward, and the effect before and after the curing was compared. The results show that LTC can prolong the service life of the road, improve the quality of road operation and beautify the appearance of the road.
