摘要
为了对比不同高速公路在设计年限内的养护效益,选择安徽省内的庐铜、界阜蚌及芜宣高速,以达到设计轴载次数的年限作为沥青路面寿命周期费用的分析期,采用费用现值法计算3条高速于寿命周期内的总养护费用现值和年平均费用现值。研究结果表明:1随着路面使用时间的增加,处治厚度较深的养护措施的使用比例上升。2养护效益最好的是庐铜高速,说明了交通轴载是影响路面养护效益最显著的因素。
To compare the maintenance effectiveness among different expresswaysthroughout the design life, three expressways including Lujiang-Tongling expressway, Jieshou-Fuyang-Fengming express- way and Wuhu-Xuancheng expressway in Anhui province were selected for evaluation. The time when the design traffic axle load times were achieved was regarded as the life cycle of the asphalt pavement for life cycle＇cost analysis,then the total maintenance cost of the present value and the annual average present value of the three expressways throughout their life cycles were calculated by means ofthe cost present val- ue method. The results showed that （1） As the pavementservice timeincreases, the ratio of maintenance measures providing thickertreatment raises. （2） Lujiang-Tongling expressway had the best economic ef- fectiveness, indicating that the traffic axle load time is the most significant factor for economic effective- ness in pavement maintenance.
