Strength Improvement of Black Cotton Soil Using Plastic Bottles and Crushed Glass Wastes

The aim of this study was to improve the strength black cotton soil for its suitability road subgrade construction using wastes from plastic bottles and glass waste powders. Currently, nondecomposable glasses have become threats human health environment. This used replace cement, since cost cement raised due energy raw material use as stabilizer in weak soil. powder (WGP) chips were mixed with sample a percentage by dry weight 6%, 12%, 18%, 24% WGP 2%, 4%, 8% chips, respectively. can be prepared similar requirement test standards reinforcement soil-glass-mix; hence, purpose geomechanical. Laboratory tests soil-mix physical properties parameters conducted. Soil laboratory results proved that natural soils classified A-7-5 per AASHTO Classification System CH Unified (USCS). Unconfined Compressive Strength (UCS) improved 91.92 kPa 688.83 kPa, California Bearing Ratio (CBR) 2.64 17.5. improvement increased ratios strips. result indicated two stabilizers very effective improving index parameters.
