Analysis on Expressway Asphalt Pavement Disease Detection and Milling and Resurfacing Maintenance Treatment
Taking a ring expressway as an example,this paper evaluates the PCI,RQI,RDI,PBI and SRI of asphalt pavement through on-site detection,determines that the main disease of the asphalt pavement is crack,and further analyzes and determines the causes of the crack.Then,according to the causes of the disease,a targeted milling and resurfacing maintenance scheme is formulated for treatment.Finally,through on-site quality detection,after milling and resurfacing,the maximum gap at the joint position is 0.5-3.0 mm,the average IRI of the road section is 0.8-2.0 m/km,and the pavement flatness is good,meeting the requirements of road operation.
