The first is using fly ash with mixing proportion varies from 10%, 15%, and 20%. In the second method, 10% cement combines with fly ash mixing proportion in the first method. Based on CBR test results, the fly-ash effectively increases the soft soil capacity with a CBR maximum of 9.31% at 20% fly ash in the first method. The second method enhances more impact than the first method with a CBR maximum of 49.36% at 20% fly ash. The swelling value keeps decreasing with the increase of fly ash content, and adding cement to fly ash-soft soil mixture can further minimize the swelling value by two times compared to only fly ash as the stabilizing agent.
