摘要
膨胀土具有显著的胀缩性、崩解性和多裂隙性等一系列的特殊、复杂的物理力学性质。本文结合宿马工业园区S303泗永路灵壁至宿城段改建工程（以下称本项目）路基的施工特点，对膨胀土掺灰改良的施工技术应用进行了探讨。
The expansive soil has a series of special and complex physical and mechanical properties such as obvious expansion, disintegration and many cracks in it. In this paper, combined with the construction characteristics of the subgrade of the rebuilt road project （（hereinafter caled the project）, the author discussed the application of construction technology of expansive soil improved by mixing lime.
