Research on skid resistance and noise reduction properties of cement concrete pavements with different surface textures

AbstractThe present study discusses the use of the new windscreen pavement/tire noise testing method and the lateral friction coefficient test vehicle to test the skid resistance and noise reduction properties of cement concrete pavements with different surface textures and to analyze the skid resistance and noise reduction mechanisms of pavements with different surface textures. The tests show that the improved noise testing equipment can effectively check the interference of outside noise and ensure the accuracy of test data. In addition, by improving the common surface texture of cement concrete pavements, the pavement noise can be reduced and skid resistance is increased. The noise of porous, exposed aggregate, and longitudinally grooved cement concrete pavements is equal to that of asphalt pavements and all of them display good skid-resistant effect.
