公路行车道宽度主要是根据设计行车速度确定的,现行《公路沥青路面设计规范》(JTG D50-2006)中只考虑了标准轴载的车道分布系数,并没有考虑轮迹在行车道内的分布规律。通过理论计算和实际比对,提出了行车道宽度同轮迹分布概率的规律,通过调整行车道宽度来改善路面受力状况,使车道内轮迹分布趋于均匀,减少路面病害,延长使用寿命,提高社会和经济效益。
The width of road lanes is mainly determined by the designed travel speed. Only the standard axle load distribution coefficient is taken into account in the current Design Specification for Asphalt Pavement (JTG D50-2006), and the distribution of wheel tracks in lanes is not considered . Through the theoretical calculation and actual comparison, the law of the distribution of the width of the roadway and the distribution of the wheel tracks is proposed. By adjusting the width of the roadway, the stress conditions of the road surface can be improved, the distribution of the wheel tracks in the lane can be even, the road disease can be reduced, and the service life can be extended , Improve social and economic benefits.
