Abstract

Increasing the bearing capacity of soils has been a recurring issue for several thousands of years and even till the present time. The attendant problems resulting from dissolving gypsum in gypseous soils in addition to the widespread use of plastic material globally has led to the use of plastic waste for reinforcing the gypseous soils. A series of tests were carried out to evaluate the benefits of utilizing recycled waste plastic bottles in improving the bearing capacity of gypseous soil. The soil is classified as poorly graded sand (SP) according to the Uniform Soil Classification System. There are three forms of soil reinforcement used in this study, non-perforated strips waste plastic, perforated strips waste plastic and irregular pieces of waste plastic. The increase in bearing capacity was more than two times original bearing capacity in dry condition. The bearing capacity of reinforced soil decreased to about 50% after leaching but it is still 1.5 times more than unreinforced soil. Conclusively, the reinforcement of gypseous soils with waste p
