摘　　要：红砂岩是一种常见的路基材料,本研究简单介绍了红砂岩路基施工项目,论述了红砂岩路基施工工艺,探索了红砂岩路基修筑技术,并总结了红砂岩路基修筑效果。得出:红砂岩路基施工需要增设预崩解环节,将红砂岩崩解为颗粒性质相对稳定的红砂岩质土后回填路基,可以减少路基土石方废弃量,降低工程造价。Red sandstone is a common roadbed material,this article briefly introduces the construction project of red sandstone roadbed,discusses the construction technology of red sandstone roadbed,explores the construction technology of red sandstone roadbed,and summarizes the construction effect of red sandstone roadbed.It is concluded that the construction of red sandstone roadbed requires the addition of a pre disintegration stage,which decomposes the red sandstone into relatively stable red sandstone soil and backfill the roadbed.This can reduce the amount of soil and rock waste in the roadbed and reduce the engineering cost.
