湿热地区沥青路面的养护对策及成本分析
Maintenance Countermeasures and Cost Analysis of Asphalt Pavement in Hot and Humid Areas
摘要
Abstract
Based on the example of an expressway asphalt pavement in Guangdong Province,this paper carried out the comparison of pavement preventive maintenance countermeasures and life cycle cost research in hot and humid areas.Considering the direct cost,indirect cost and residual value of asphalt pavement maintenance,it also compared and analyzed the effects of maintenance countermeasures and timing of grouting,repair,slurry seal and thin overlay on pavement surface condition index and life cycle cost.The result shows that,the preventive maintenance of asphalt pavement is delayed by one year,and the life cycle cost of pavement increases by about 16.It is crucial to reduce the cost and prolong the service life to start preventive maintenance when the road pavement is in good condition.关键词
