层间摩擦系数对路面结构受力影响分析

路面层间接触条件会显著影响道路性能。以典型沥青路面结构为依托,以壳牌设计软件BISAR3.0为计算工具,对沥青路面在不同层间接触条件下的力学响应分布进行了计算和分析。结果表明:层间非完全连续时路面结构往往处于不利的受力状态,并建议沥青路面在基层施工后一定要做好过冬防护措施。

Influence of Iriction Coefficient Between Pavement Layers on Structure Stress

The contact conditions of pavement layers will affect the pavement performance remarkably. Based on typical pavement structure, taking BISAR3.0 Shell Design Software as computational tool, the paper calculates and analyzes the distribution of mechanical response of asphalt pavement under different contact con- ditions of pavement layers. The result shows that the pavement structure is usually at an adverse stress state when the contact condition of layers is incompletely continuous. Therefore it is recommended that the protective mea- sures in winter for asphalt pavement must be implemented after the construction of base.
