Abstract: 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 mixed with other materials an d to form into the exposed-aggregate cement concrete pavement，According to the work ability 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.

Key words: road engineering, exposed-aggregate cement concrete pavement, gradation, performance, anti-skidding performance

摘要： 针对露石水泥砼路面的抗滑性能进行研究．采用室内试验：对3种不同级配的粗集料，每种级配又分别采用3 种不同的砂率进行试配成型并进行表面露石工艺处理，在考虑水泥砼和易性及强度的同时综合露石水泥砼成型块 表面的抗滑性能，确定露石水泥砼施工工艺的最优粗集料级配和砂率，结果表明，集料的合理级配对露石水泥工艺 处理的路表粗糙均匀程度和路表的抗滑性能有着积极意义，露石水泥砼路面具有良好的路用性能.
