Study optimization cement content of cement treated base (CTB) using compressive strength parameter

Abstract Cement Treated Base (CTB) is a foundation layer (base course) on flexible pavement and the development of soil-cement commonly used in construction that receives high loads. Generally, CTB combination coarse aggregate (split), fine aggregate, cement, water with zero slumps. The purpose this study was to determine optimum cement content mixture variations 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5% dry weight effect compressive strength resulting CTB. Experimental research laboratory 15/30 cm cylindrical specimens carried out analyzed. results showed for material 3.75% which obtained through graph relationship between content, from all made 4% 54.21 kg/cm2 meets general specifications 2018 Highways, namely 45 – 55 kg/cm2.
