高等级公路沥青路面设计中的重要问题探讨

Discussion on Key Problem in Design of Highway Asphalt Pavement in High Garde

沥青路面较易出现不同程度的疲劳开裂和反射裂缝、麻面、剥离、掉粒松散、坑槽、车辙等早期破坏现象,影响沥青路面质量的因素较多,工程设计是其中很关键的一个因素,工程设计质量的高低在很大程度上决定了路面质量的好坏。结合工程设计实践经验,对高等级公路沥青路面工程设计中应注意的有关问题进行探讨,并提出了具体的意见和建议。

There are manyfactors that affect bituminous pavement design.It is hard to design worthwhile and rational pavement structure by simply and mechanically applying the present standard.The paper discussed the means of solving the problems in bituminous pavement design to acquire the worthwhile and rational pavement structure.
