含有再生层的新建路面结构优化研究

Contains the New Pavement Structure Layer Optimization Research

根据我国可持续发展的要求,提出了沥青冷再生技术。以新疆地区新建沥青路面结构设计方法为参考,采用室内试验的方法制备再生材料,以此进行路面结构设计。针对当地的交通等级和原路基情况,对新建路面结构进行优化设计,研发了一种含有再生层的新建路面结构。最后对冷再生材料参数进行敏感性分析,研究了冷再生层厚度、土基模量对路表弯沉的影响。希望对今后路面结构优化研究提供借鉴。

According to the requirement of the sustainable development in our country,and put forward the asphalt cold regeneration technology. New asphalt pavement structure design method in Xinjiang area for reference,adopt the method of indoor test preparation of renewable materials,pavement structure design. To solve the problem of local transportation level and roadbed,optimize the new pavement structure design,developed a new pavement structure containing the regeneration layer. Finally to cold regeneration material parameters sensitivity analysis,studies the cold regeneration layer thickness,soil modulus,modulus of asphalt concrete road table the influence of deflection. Hope to provide theoretical guidance for the future pavement structure optimization research.
