| Abstract: | It is proposed that the linear semi-log relation of water content to soil strength be used as a means of identifying and classifying soils. The relation can be specified by two parameters proposed to be named trafficability limit and strength index. Together these two parameters will provide more useful information about a soil for the conduct and analysis of traction and mobility testing than any other classification system now in use. The parameters also have potential for additional correlations with measures of soil behavior in dynamic testing. Data are presented to demonstrate the feasibility of the proposal. |
