EFFECTIVENESS OF SUGARCANE STRAW ASH AND PULVERIZED USED PAPER FOR STABILIZATION OF VERTISOLS SOIL

In the discipline of civil engineering, foundation plays a crucial role in supporting and containing loads complete structures. Therefore, needs to be strong enough increase any structure's useful life. The soil has direct impact on foundation. Vertisols is with unstable weak that stabilized make suitable for construction purposes. study determine effectiveness pulverized used paper sugarcane straw ash as stabilizers vertisols San Isidro, Nueva Ecija. Natural was classified A-7-6 AASTHO classification system CH group name by USCS system, indicates high clay. index properties natural showed it poor not applicable engineering Liquid limit plasticity values 60% 35%, respectively, suggested plasticity. There gradual decrease value 25% at 15% SCSA+PUP compared this progressively stabilizing. addition, there are increases compaction parameters CBR 14.0283 kN/m3 5.47 100% MDD 13.69476 4.83 MDD, respectively. But these fall from requirement sub-base coarse, however, considerable changes using SCSA PUP. This research aimed PUP stabilizing
