SOFT Soil Subgrade Stabilization Using Waste Paper Sludge Ash (WPSA) Mixtures
This paper presents findings on the soft soil stabilization using waste paper sludge ash (WPSA). A laboratories testing was conducted to determine the compressive strength, total shear strength and effective shear strength on soft soil subgrade stabilized using WPSA mixtures. Instead, the microstructure of soft soil and stabilized soft soil was investigated to evaluate the role of WPSA to the strength of stabilized soft soil. The soft soil subgrade sample, categorized as slightly sandy CLAY of intermediate plasticity used in this study was stabilized using Class-C of WPSA. The first objective is to determine the maximum compressive strength and optimum percentages of WPSA mixtures. The second objective is to determine the total shear strength and effective shear strength of soft soil stabilized with optimum percentage of WPSA. The third objective is to investigate the effect of WPSA to the strength of stabilized soft soil by microstructure testing by scanning electron microscopic test (SEM). This study involved three main testing. First testing was unconfined compression test to determine the compressive strength. Second testing was consolidated undrained test to determine the total shear strength and third testing was consolidated drained test to determine the effective shear strength. Third testing was microstructure testing by scanning electron microscopic test (SEM). The result shows, the addition of 10 % WPSA were giving the highest compressive strength about 737 kPa and improved the total strength and effective strength to stabilize the soft soil due to the crystal formation from the pozzolanic reaction.
