摘　　要：红土砾石料作为一种特殊的水泥稳定基层材料,经水泥改良后具有其非常高的承载能力,在石料缺乏和开采难度大的地区是公路常用的基层材料,但由于其特殊性能,在厂拌法施工中与级配碎石水泥稳定料性能差别极大,因此在开采、筛分、拌和、摊铺和养护中采用一些特殊的技术处理措施来保证其施工性能和工程质量。Red soil gravel material,as a special cement stabilized base material,has a very high bearing capacity after cement improvement.It is commonly used as a base material for highways in areas where stone materials are scarce and difficult to mine.However,due to its special properties,its performance differs greatly from that of graded crushed stone cement stabilized materials in factory mixing construction.Therefore,special technical treatment measures are adopted in mining,screening,mixing,paving,and maintenance to ensure its construction performance and engineering quality.
