摘要
半刚性基层路面的性能评价是对路面养护、铺装、维护的有力依据。然而依据现行公路技术评价体系对西部高速公路进行评价时,路面状况指数经常超限。针对这一问题,文章基于国内外沥青路面破损及评价研究现状,从计算弯沉值、路面结构强度指数PSSI、路面车辙状况RDI等方面,研究了半刚性基层沥青路面结构破损状况的计算方法,并结合工程实例进行了应用分析,为沥青路面半刚性结构破损评价提供理论依据。
The performance evaluation of semi-rigid base-layer pavement is the strong basis for pave- ment maintenance,paving and maintenance.However,when evaluating the expressway in western re- gion based on current highway technology evaluation system, the pavement condition index often goes over the limit.Regarding this problem, based on domestic and foreign asphalt pavement damage and evaluation situation, and from the aspects of calculating the deflection value, pavement structural strength index PSSI,and pavement rutting condition RDI,this article studied the calculation method of semi-rigid base-layer asphalt pavement structure damage condition, and conducted the application analysis combined with engineering practices,thereby providing the theoretical basis for the semi-rigid structure damage evaluation of asphalt pavement.
