摘　　要：针对市政道路不良路基填料改良问题,提出一种新的施工控制技术,采用向高液限土中掺入石灰粉的方式增强填料的力学性能,为不良路基施工提供高性能的填筑材料,有效解决了路基承载力低、变形、滑移等问题。该方案不仅可以增强粗颗粒的骨架作用,改善土质级配,还能有效预防土质膨胀、分裂等情况发生,使市政道路建设质量得以提升。Aiming at the improvement of poor subgrade fill on municipal roads,a new construction control technology is put forward.Lime powder is added to high liquid limit soil to enhance the mechanical properties of the fill,which provides high performance filling material for poor subgrade construction and effectively solves the problems of low bearing capacity,deformation and slip of subgrade.This scheme can not only enhance the skeleton of coarse particles,improve soil gradation,but also effectively prevent soil expansion and splitting,so that the quality of municipal road construction can be improved.
