摘要
由车辆荷载在道路横断面的不均匀分布引起的高速公路路面局部破坏是影响路面寿命的主要原因之一。根据行车视觉环境与驾驶员行为之间的关系,利用视觉干预的理念,采用不同道路交通标线的组合使车辆行驶轨迹横向偏移,轮迹横向偏移后,路面横断面内受力趋于均匀,延长了路面寿命。研究成果为路面养护管理提供一种新方法。
One of the main factors which affect pavement life has a lot to do with vehicle load and uneven wheel tracks transverse distribution.According to the relationship between visual environment and drivers＇ behavior,this study takes advantage of the visual interference idea in order to shift wheel tracks transverse distribution by taking reformation of existing traffic markings.As a result,the impact of vehicle load on the pavement is well-distributed and thus life of pavement is prolonged.The result of this study offers a new method for pavement maintenance and management.
