【Abstract】 According to the natural climate conditions of Hunan aream the general methods of the concrete pavement structure drainage in some speacial geological conditions are discussed. In this paper, the more perfect methods are provided for the design of drainage system in concrete pavement. Further, based on the contrast experiments about drainage base course and anti penetrate subbase course, the authors put forward the main design parameter of drainage base and anti penetrate subbase, as well as the construction methods of pavement structure drain system.更多还原
