摘要
加州承载比即CBR,由美国加利福尼亚州公路局首先提出来,是用于评定路基土和路面材料的强度指标。CBR试验是公路路面设计的重要组成部分。本文根据大量不同土料的CBR试验数据,对CBR试验的作用机理和影响因素进行了研究,并对有关CBR试验规程中存在的问题进行了探讨。
CBR is called California Bearing Ratio, which was put forward by the Highway Administration Bureau of California in USA. CBR is used to evaluate the strength index for subgrade soil and road surface material, and the CBR test is the important part for the surface design of highway. Based on the data of CBR tests for different soils, the mechanism and influencing factors are studied, and the problems existed in the regulation for CBR tests are discussed.
