Application Research on Treatment of Slurry Disease of Asphalt Pavement
In China,the asphalt pavement base is mostly made of semi-rigid pavement structure.As the service life of the road surface increa-ses,due to the material properties of the semi-rigid pavement structure,poor drainage of pavement base layer and heavy traffic on the road,slurry disease is widely distributed on asphalt pavements,seriously affecting road safety and accelerating damage to asphalt pavement.In order to extend the service life of asphalt pavement and reduce the cost of maintenance.Based on the Xiang'an Avenue defect repair project in Xia-men,through methods such as investigation on asphalt concrete pavement distress and analysis of the causes of the defect,and then according to the findings of investigation judged the development degree of the defect.After the completion of the repair project,through on-site observa-tion,the experimental results was analyzed.The results showed that,targeted suggestions are made for the treatment of the roadbed defect and the subgrade drainage scheme.The practice results show that slurry disease in the development stage,excavating the pavement structure and treating the pavement base disease combine with setting blind drains can effectively solve the problem of slurry disease promptly.This research has significant economic benefits and measurable social significance.
