Application of Porous Ultra-thin Wearing Course in Single Lane Maintenance of Porous Asphalt Pavement
In order to improve the service performance of porous asphalt pavement,and solve the distresses such as the attenuation of skid resistance and the slight raveling,the specific engineering case was analyzed by paving porous ultra-thin wearing course in the single lane maintenance of porous asphalt pavement.Firstly,the construction scheme was introduced of the engineering case,also the key technology of porous ultra-thin wearing course from the aspects of mix ratio design and construction technology.Then the application effect of porous ultra-thin wearing course was verified based on the test results of pavement construction quality and pavement side-way force coefficient.The analysis results show that the porous ultra-thin wearing course exhibits good mixture performance and excellent anti-skid performance,and can be well applied in the single lane maintenance of porous asphalt pavement.
