乌干达高液限红黏土路用性能研究

Research on Road Performance of Ugandan High Liquid Limit Red Clay

采用中国标准对应用在乌干达KE高速公路路基填筑的高液限红黏土的物理特性和路用性能进行研究。研究包括对其天然含水率、液限、塑性指数、比重和颗粒的分析,并对其进行了加州承载比(CBR)试验、直接剪切试验和固结试验以进一步探究高液限红黏土的路用性能。研究表明,乌干达地区的高液限红黏土各项性能可以满足路基工程应用的需要。

The physical properties and road performance of high-liquid limit red clay applied to the filling of the KE highway subgrade in Uganda are studied using Chinese standards.Relevant research includes the analysis of its natural moisture content,liquid limit,plasticity index,specific gravity,and particles.The California Bearing Ratio(CBR)tests,direct shear tests,and consolidation tests were carried out to further explore the road performance of high liquid limit red clay.Studies show that the properties of high liquid limit red clay in Uganda can meet the needs of roadbed engineering applications.
