沥青路面再次开裂模式研究

Research on Recracking Model of Asphalt Pavement

本文通过模型计算与分析，对沥青路面再次开裂模式进行了研究．研究表明，沥青路面再次开裂时，视内外条件不同，可出现先从路表开裂与先从面层底开裂两种模式．文中分析了两种模式的发生条件、计算公式及影响因素，其成果可供工程实际参考．

On the basis of model calculation and analysis, this paper developes research on recracking model of asphalt pavement.The results owing to the external and internal conditions,when asphalt pavement recracks,the cracking may begin from the surface or from the bottom of the surface layer.The condition why does it take place at surface or at the bottom of surface layer,formula and the influencing factors are discussed. The results gave referencing value for practical uses.
