Abstrakt: An experimental laboratory program was conducted to understand the feasibility of steel slag and lime in the subgrade layer. The test was conducted on natural clay soil, lime, lime + steel slag stabilized cohesive subgrade soil. The lime portions were 2%, 4% and 6%, respectively. Similarly, steel slag was added to 20%, 25% and 30%, respectively, by the mass of dry soil. The strength of lime soil and lime + steel slag + soil increases with increasing curing period. The 7-day unconfined compressive strength (UCS) 2% lime soil and soil+20% steel slag + 2% lime is 3.20 MPa and 3.87 MPa, respectively. Eventually, this study supports the use of steel slag and lime in the construction of subgrade stabilization. Therefore, it is found that a lightweight deflectometer can be used as a quick strength evaluating tool on modified subgrade soil in the laboratory. [ABSTRACT FROM AUTHOR]
