The south china is rich of rainfall,and the traffic safety in highway' s crooked road position is uncommonly. The drainage asphalt-OGFC has good drainage channel inside. It willn' t produce the problem of drift water and flog of water like ordinary pavement, and also it owns roughly outside construction. So it' s a kind of pavement material which has widely future prospects. As to the engineering project' s experience before, adopt CAVF method, three curve graduation is chosed to design material, for achieve better function of shore framework and long drainage channel. The research shows, this method has important reference function for complete method of OGFC material design.%华南地区降雨丰富,高速公路弯道位置的行车安全问题十分突出.排水式沥青路面(OGFC)具有良好的内部排水通道,不会像普通路面那样产生水漂和水雾问题.还具有粗糙的表面构造,是一种极具应用前景的路面材料.针对以往的工程经验,研究从采用CAVF法、选择三个级配曲线进行设计材料,以实现更好的骨架支撑作用和长期有效排水通道.实验研究表明,该方法对于完善OGFC材料设计方法,具有重要的借鉴作用.
