“…Use of such waste plastic materials in civil and construction engineering applications has become an attractive alternative to disposal to reduce both the cost of disposal and waste quantities. Thus, numerous studies have been investigated the use of different types of waste and recycled plastics in concrete and geotechnical applications (Ahmed et al 2011;Siddique et al 2008;Marzouk et al 2007;Dutta and Sarda 2007;Choi et al 2005;Dutta and Venkatappa Rao 2004;Sobhan and Mashnad 2003;Montardo et al 2002;Benson and khire 1994;Bayasi and Zeng 1993).…”

A proposed regression model was developed based on experimental data using regression analysis method to predict the strength of sand reinforced with strips of waste polystyrene plastic type. Three different variables were studied to investigate the behavior and strength of reinforced sandy soil with waste plastic strips. These are the content, size and aspect ratio of plastic strips. For this purpose, a series of unconfined compression and splitting tensile tests were conducted on unreinforced and reinforced sand specimens. Test results showed that using strips of waste plastic polystyrene type improved the strength of the tested soil. Increasing content of waste plastic has a more significant effect on the enhancement of splitting tensile strength compared to the enhancement of compressive strength. Content, size and aspect ratio of waste plastic strips have significant effects on the improvement of strength. Utilization of such waste plastic type, which polystyrene, in this way will help in reducing the quantity of solid waste as well as reducing the cost of ground improvement. Results showed that multiple linear regression models can accurately predict the strength of sand reinforced with waste plastic strips within the range of the studied variables in this paper.Consequently, using such regression models will save time as well as reduce laboratory costs.

“…For subgrade applications, several researchers have investigated the mechanical and physical properties of uncemented and cemented fine grained geotechnical material reinforced by different types of materials such as fibers, shredded tires, plastic waste, and geogrid elements [12][13][14][15][16][17][18][19]. Hooper and Allen [6] investigated the mechanical and physical effects of adding RAS to soils.…”

An experimental work was conducted to study the use of factory-waste roof shingles to enhance the properties of fine-grained soil used in road works. Cement kiln dust (CKD), a cogenerated product of Portland cement manufacturing, was used as a stabilizing agent while the processed shingles were added to enhance the soil tensile strength. The effects of shingles on strength and stability were evaluated using the unconfined compressive strength, splitting tensile strength, and California Bearing Ratio (CBR) tests. The results showed that the use of CKD alone resulted in a considerable increase in the unconfined compressive strength but had a small effect on the tensile strength. The addition of shingles substantially improved the tensile strength of the stabilized soil. A significant reduction in the capillary rise and a slight decrease in the permeability were obtained as a result of shingle addition. An optimal shingle content of 10% is recommended to stabilize the soil.
