天津市高速公路货车轮胎接地特性调查与分析

Survey and analysis on truck tyre grounding characteristics on Tianjin city highway

货车轮胎的接地面积和接地压强是沥青路面设计的重要参数,实测得到了天津市高速公路典型货车轮胎在不同轴载作用下的接地面积与接地压强,统计分析得到了轮载与轮胎接地面积的相关关系计算公式,从而有利于了解实际货车的接地状态,优化沥青路面的结构设计参数,提高设计质量。

The truck tyre grounding area and grounding strength are significant parameter in asphalt pavement design. Actual survey gets the grounding area and grounding strength of truck tyre under different axis loading on Tianjin city highway. Statistic analysis obtains the relevant relation calculation formula of type load and tyre grounding area. As a result, it is good for understanding actual truck grounding condition, optimi- zing asphalt pavement structure design parameter and improving design quality.
