摘　　要：为减少城市沥青路面的裂缝、车辙、坑槽等不同类型的结构性破损,构建综合性养护方法,依据结构破损的成因设计养护措施。通过均衡多方面路面性能,根据路面破损程度、综合性养护方法和路面评估指标间的关联性,与精表处技术和微表处技术2种方法对比,评选城市沥青路面结构破损的最优综合性养护方法,并进行仿真试验和路面试验。结果表明:综合性养护方法的效果较全面,破损状况指数为92.78,裂缝率为0.32%,车辙深3.7 mm,效果比其他2种方法好,能有效修复沥青路面破损,提升路面防滑性和耐用性。To reduce different types of structural damages such as cracks,ruts,and potholes on urban asphalt pavements,a comprehensive maintenance method is developed to design corresponding maintenance measures based on the causes of structural damage.By balancing various aspects of pavement performance,and considering the correlation between pavement damage severity and comprehensive maintenance methods and pavement evaluation indicators,the optimal comprehensive maintenance method for urban asphalt pavement structural damage is selected and compared with two methods:precision surface treatment technology and micro-surfacing technology,and simulation and road tests are conducted.The results show that the comprehensive maintenance method has a comprehensive effect,with a damage index of 92.78,a crack rate of 0.32%,and a rut depth of 3.7 mm.It is better than the other two methods,effectively repairing the damage to the asphalt pavement and improving its skid resistance and durability.
