摘　　要：采用干土法和湿土法对红粘土的路用特性进行了试验研究.研究结果表明,不同的试验方法对试验结果有明显的影响.从红粘土的矿物组成和结合水分布等微观结构的角度,探讨了导致不同试验结果的原因.针对公路部门的生产实际,提出了红粘土路基填料的试验方法,为红粘土路基的合理填筑提供了理论依据.Red clay is a broader range of distribution in south part of China,and has special causes,mineral composition and structure.The road performance of red clay is studied through the watering method and water-reducing method by tests.Different test methods have significant effect on test results,and explored the reasons leading to different results from the red clay with mineral constituent,combination of water distribution and other micro-structure.This paper proposes an experimental method of red clay roadbed filling for actual production of highway department,and provides a theoretical basis for reasonable filling of red clay sub-grade.
