【摘要】 结合昌樟(南昌—樟树)高速公路水损害的特点和江西省气候水文特征,分析昌樟高速公路沥青混凝土路面产生水损害的主要原因。综合考虑沥青混凝土路面各个结构层的排水性能,从中央分隔带、路面结构内部、集水井、路堑边沟加深以及特殊路段等方面出发,提出解决昌樟高速公路水损害的设计方法和施工工艺,经过对施工后昌樟高速公路排水效果和路面水损害的调查,表明这些措施能够有效地降低沥青混凝土路面的水损害,并且在施工过程中几乎不影响交通。更多还原

【Abstract】 On the basis of the characteristics of water damage of Chang-Zhang(Nanchang-Zhangshu) Expressway and investigations of climate in Jiangxi Province,the main reasons of water damage of this expressway are analyzed. Considering median separator,inner of pavement structure,collecting well,deeping side ditch of roadcut and special sections of expressway,some designing methods and construction techniques are put forward in order to radically solve the water damage problems.By the investigations,these measures can effectively reduce the water damage and hardly disturb vehicle flow during construction.更多还原
