摘要
为改变沥青路面车辆轮迹的分布规律,使沥青路面承受荷载趋于均匀,提出了视觉干预方法及其适用条件,根据上三高速公路的观测结果,基于Miner疲劳累积损伤准则,计算分析了视觉干预的效果,结果表明,采用该方法可延长沥青路面使用寿命17%。
In order to change wheel track＇ s distribution of asphalt pavement, which cause load applied on asphalt pavement tends to be uniform, the article propose the visual intervention method and its applicable conditions, According to the observation results of Shang San-highway, the effect of visual intervention was analyzed based on the cumulative fatigue damage criterion of Miner, results show that, this method can prolong the service life 17% of asphalt pavement.
