摘要
轮胎与路面间接触压力具有很明显的非均布性,根据轮胎胎面花纹的类型,提出荷载简化模型,并利用有限元计算分析不同荷载作用下的沥青路面结构响应。结果表明,轮胎与路面接触面的局部区域内,不同荷载模式的影响相当大,这对进一步解释路面面层的破坏现象提供有益的参考。
The interfacial pressure between tire and pavement exhibits a highly non- uniform distribution over the contact area. On the basis of abundant literature, simplified load models were put forward according to the tire tread patterns. The pavement response under the simplified load models was obtained through finite - element method. The results show that the influence of different load models is remarkable near the contact area. These results may be a possible explanation of near- surface pavement distress evolution in asphalt pavement.
