Mechanical Behavior of Plastic Strips-Reinforced Expansive Soils Stabilized with Waste Marble Dust

Expansive soil needs to undergo treatment be used as safe foundation for roads and buildings. From an environmental conservation economical point of view, the usage agricultural industrial wastes is best option. In this study, effects utilizing plastic waste marble dust on engineering properties expansive soils were examined. Various laboratory tests carried out sampled by adding 10, 15, 20% 0.25, 0.5, 0.75% 5 × 8 mm2 strips. The test results showed that there are good enhancements strength parameters due addition With increase in percentages strips, California Bearing Ratio (CBR) values rise. dust, unconfined compressive (UCS) linearly, while they only up 0.5% with As proportions strips increase, soil’s free swell CBR decreased significantly. This shows pollution can utilized strengthen weak subgrade minimize its swelling properties. Therefore, study found treated polyethylene terephthalate (PET) a material since it fulfills minimum requirement needed standards.
