【摘要】 为了更好的分析小半径曲线段沥青路面病害特征,对重载交通条件下直线段和不同半径(35m/50m/65m)弯道段汽车横向轮迹荷载分布进行了调研和分析,得出了直线段和不同半径弯道段轮迹荷载横向分布特征,以此为依据分析认为小半径弯道沥青路面病害主要为疲劳网裂、水损害,研究了病害的产生机理,并结合沥青路面设计、施工给出了相应的建议。更多还原

【Abstract】 In order to better analyze the characteristics of the damage to the small-radius curved asphalt-surfaced section of roads,the horizontal wheel-load distribution of the straight-line segment and three different-radius(35m/50m/65m) curved sections under heavy-loaded traffic is looked into and analyzed in the paper,according to which the characteristics of the load distribution of them are respectively obtained.Upon the basis of the analysis,it is concluded that the damage to the small-radius curved asphalt-surfaced section of the mountainous roads mainly consists of fatigue net cracks and water damage,the causes of which are seriously studied.According to this conclusion,some corresponding suggestions,with the design and construction of asphalt pavement taken into consideration,are presented in the paper.更多还原
