摘要
本文通过对粉土的物理力学特性的分析和讨论，指出了在粉土地区用粉性加固土做干线公路路面基层造成的破坏机理和产生的主要路面病害。在此基础上，提出了适合该地区的公路路面基层结构形式和基层类型。
This paper through the analysis and discussion of physical mechanics characteristics for mealy soil,points out creative the destruction mechanism and main disease of road surface of using meanness reinforced siol for highway basic level in mealy soil area. On the basis,the author raises the suitable basic level structure forms and types of highway road surface in the area.
