| Abstract | In recent years, in order to improve road quality and road usage environment, the maintenance units of road authorities at all levels of the government have tried their best to study how to use new construction methods and new materials, hoping to gain public recognition and good reputation with limited maintenance funds and manpower. Maintenance effectiveness. Especially for roads in remote areas with steep slopes, it is relatively difficult to lay asphalt concrete pavement. Because the slope roads in Shiding mountainous area are paved with fine-grained materials and smooth surfaces, the nominal particle size is 3/8" asphalt concrete pavement. It often causes the pavement to gradually deform and rut in less than a year after paving. The proportion design uses a rough surface layer with a lot of coarse-grained materials on the surface. The nominal particle size is 3/4" recycled large-grained asphalt concrete material. pavement to overcome the hazard factors of overturning and achieve efficient road maintenance methods. Research results show that after laying and curing recycled large particle size asphalt concrete with a nominal particle size of 3/4", the Pavement Condition Index (PCI) survey data and one year after the improvement was completed, the values fell into 100. The pavement condition is classified as "good". According to the survey data of the Advanced Acceleration Roughness Index (AARI), one year after the improvement was completed, the values fell between 3.27 and 3.35, and the road condition level was classified as "comfortable". It can be seen that the current condition of the road has been significantly improved after its construction. It is suitable for maintenance of steep road sections on hillside areas and helps to improve road quality and management performance. |
