Experimental Investigation of the Effect of Grain Size Distribution on CBR (%) Values

Abstract

Various types of soil are widely used as fill materials in civil engineering applications. The physical and engineering properties of these materials are the primary parameters that determine their suitability for specific purposes. The performance and stability of structures depend largely on the design parameters of the fill material and the accurate prediction of how these parameters may change over the life of the structure. This study aims to experimentally investigate the effects of swelling potential, liquid limit, mean grain size and clay content of soils on the California bearing ratio (CBR %). For this purpose, seven different soil samples were prepared by adding different proportions of sand and gravel to a fine-grained, low plasticity kaolinite clay, resulting in soils with different grain size distributions and consistency properties. The samples were compacted to their optimum moisture content and maximum dry unit weight and then subjected to CBR tests under both dry and water-saturated conditions (after 96 hours of soaking). The CBR (%) values obtained from both conditions were compared and the ΔCBR (%) changes were calculated. The experimental findings showed that the change in CBR (%) values was significantly influenced by the swelling amount, liquid limit, mean grain size, and clay content. In particular, swelling caused a decrease in CBR (%) values ranging from 25% to 63%. These results indicate that the swelling potential of soils has a significant effect on their CBR (%) performance.
