Research On A Complete Set Of Technology About Noise-reducing Permeable Asphalt Pavement

With the rapid development of China’s highway,there are higher requirements on theroad durability,serviceability and safety.At the meanwhile,environmental problem of road areincreasingly becoming a concern of people.To stimulate coordinated and sustainabledevelopment of asphalt pavement and create a harmonious environment between human andnature is an important issue in conpemporary society.As a new type ofpavement,noise-reducing permeable asphalt pavement help ability of anti-sliding meet therequirements of asphalt pavement and solve the problem of low friction coefficient because ofits good noise reduction,slip resistance and mist suppression and other surfacefeatures,ensuring the safety of driving.This paper is based on domestic and abroad achievements and the results of laboratorytests,combined with Shenzhen-Hong Kong Western passage project.The main method isconducting research on proportioning design,road performance,structural design,constructiontechnology and quality control methods of noise-reducing permeable asphalt pavement.Finally,the structural design for noise-reducing permeable asphalt mixture can beobtained. Base on the mechanism tire-road noise,CTT method is used to test the noise ofnoise-reducing permeable asphalt pavement on the scene.Compared with ordinary concretepavement,the results show the superior performance of noise-reducing permeable asphaltpavement.According to the analysis of rainfall in Shenzhen,a suitable drainage system for thelocal climate and environment is showed in the paper.
