贵州省水稳基层就地冷再生路面结构设计研究

Research on Structure Design of Cement Stabilized Base Course On-site Cold Regeneration Pavement in Guizhou Province

文章针对贵州省山区公路所用筑路材料,研究了不同新旧料比例下冷再生混合料的力学指标及路面结构设计参数范围;基于弹性层状体系理论,提出由路表弯沉反算基底回弹模量的拟合公式,并根据双圆均布垂直荷载作用下的弹性层状连续体系理论提出了冷再生路面设计流程,为贵州省山区公路的基层就地冷再生路面结构设计提供了参考。

This article researched mechanics index and pavement structure design parameter scope of cold regeneration mixtures under different old and new materials proportions aiming at road material used by mountain road in Guizhou Province;based on elastic layered system theory,it proposed the fitting formula of inverse computation of base rebound modulus with surface deflection,and also came up with design flow of cold regeneration payment according to elastic layer continuous system theory un-der the action of bicircular and equispaced vertical load which provided reference for base on-site cold regeneration payment structure design of the mountain road in Guizhou Province.
