谈排水性沥青路面结构设计

Structure Design of Porous Asphalt Pavement

通过对各种路面材料的性能试验和混合料配合比的设计研究,得到合适的排水性沥青路面材料和矿料级配表,在此基础上探讨新型的排水性沥青路面结构形式,并研究沥青路面坡度、路肩排水、超高段路面表面排水和中央分隔带排水等的设计。

Through the performance tests on various pavement materials and research on mix proportion of mixture, the proper materials and mix proportion of porous asphalt pavement are ascertained. On the basis, the structure form of new-style porous asphalt pavement is discussed, and the items like pavement grade, shoulder drainage, surface drainage of superelevation transition section, drainage of median separator and so on are de- signed.
