In engineering practice, the earth construction requires the compaction of the existing subgrade by improving the density and strength of the data. All types of earth structures, i.e., highways, pavements, etc., rest directly on the soil beneath them. The safety of these entities depends upon the strength/bearing capacity of the soil over which these are constructed. Therefore, a proper analysis of the soil properties and the design of their compression parameter become necessary to ensure that these structures remain stable and are safe against unequal settlements. To determine the suitability of any soil type for use as subgrade, subbase, or base material, one of the parameters generally used is the California bearing ratio (C.B.R.). The coarse aggregates available as a reinforcing material can enhance soil properties and increase its C.B.R. value. This paper will study the effects of coarse aggregates on the C.B.R. value, determine suitable size range of aggregates with their percentage, and their application for the earth structures.
