Utilization of coal fly ash to enhance the bearing capacity of road base

Abstract Coal is responsible for the generation of around 38 percent power that used throughout entire planet. In last two decades, there has been a rise in number chances recycling and usage fly ash from coal combustion due to its hydrophobic cementitious properties. However, still limited commercialization (CFA) road construction. The focus this research determine bearing capacity CFA-treated crusher run as base course. order appropriate percentage CFA, was mixed with various percentages Class F including 10%, 15%, 20%, 25%. proctor Compaction test (PCT), soaked unsoaked California Bearing Ratio (CBR) tests, Unconfined Compressive Strength Test (UCST) were then evaluate crusher. result shows CFA increased, Optimum Moisture Content (OMC) Maximum Dry Density (MDD) decreased compared control specimen. CBR 20% increased by approximately 32% 26% respectively Therefore, it proven utilization up into could enhance base.
