Technology for Low Noise and High Anti-skidding Exposed-aggregate Cement Concrete Pavement

Through simulating test in the laboratory,further anti-skidding performance of exposed-aggregate cement concrete pavement was studied.The first step was to select three kinds of coarse aggregate with different gradations,then each one selected three different fine-coarse aggregate ratios,which separately mixedwith other materials and to form into the exposed-aggregate cement concrete pavement.According to the workability of cement concrete,strength and anti-skidding performance of exposed-aggregate cement concrete pavement,the optimum gradation of coarse aggregate and appropriate fine-coarse aggregate ratio were determined.The results indicate that the optimum gradation of aggregate plays an important role in surface uniform coarseness and in surface anti-skidding performance towards exposed-aggregate cement concrete pavement,which is of excellent performance.
