城市沥青混凝土路面大修的技术探讨

城市沥青混凝土路面经过长时间的使用，路面结构层会出现损坏，性能满足不了使用要求。通过对老路的路面平整度、路面病害、路面强度(弯沉)进行调查和检测，对路面行驶质量、路面损坏状况、路面结构强度进行评价，针对不同路段的损坏情况提出相应的大修措施，提高道路承载力、改善平整度、改善路面功能，使路面各项指标达到相应要求，恢复道路使用性能，提高道路服务品质。

Discussion on Overhaul Technology of Urban Asphalt Concrete Pavement

After long-term use of urban asphalt concrete pavement, the pavement structure layer will be damaged, and its performance cannot meet the use requirements. Through the investigation and detection of the pavement flatness, pavement disease and pavement strength (deflection) of an old road, the pavement driving quality, pavement damage condition and pavement structure strength are evaluated. Aiming at the damage conditions of the different road sections, the relevant overhaul measures are proposed in order to improve the road bearing capacity, flatness and pavement functions to make various indexes of pavement reach the relevant requirements, recover the use performance of road and improve the service quality of road.
