“…Perera et al (2022) investigated the effect of using crushed waste glass with a particle size of less than 5 mm in clayey soil stabilization. As the chemical analysis showed the CWG material is mainly composed of oxides of silicon, calcium, sodium, and aluminum comprise (Perera et al, 2022).…”

“…The maximum OWC was found at 10% CWC content, whereas it was the lowest at 15% CWC content. Perera et al (2022) investigated that the maximum dry density of stabilized cohesive soil increases insignificantly with increasing crushed waste glass content (by a maximum of 5%), whereas the optimum water content decreases (by a maximum of 14%). Bawadi et al (2020) reported that the MDD and OWC parameters depend not only on the content of natural fiber but also on their type.…”

One of the biggest challenges of recent civil engineering is the need to make it sustainable by implementing environmentally friendly and cost-effective solutions. The search for new materials and technologies is an important and current issue also in the strengthening of soft soils. In the soft soil stabilization process, conventional materials (cement and lime) are being replaced by waste materials, such as stone slurry waste, spent coffee grounds, rice husk ash, crushed waste concrete and glass, natural fibers, sawdust, waste tire rubber and plastic waste materials. Appropriate waste admixture content contributes to soil reinforcement by reducing compressibility and increasing maximum density and shear strength. The application of waste as an admixture is an economically and ecologically beneficial method of soil improvement. It eliminates the cost of materials and helps to reduce the problem of waste disposal, which is sometimes very expensive and problematic. The study aims to analyze the effect of waste materials on improving the physical and mechanical properties of soils based on the research results presented in the literature.

This research evaluates the changes brought about by the addition of asphalt emulsion and steel filings in clayey soils for subgrade in urban pavements. For this study, different dosages of each additive were established, being 1%, 2%, 4%, 8%, and 15% for the steel filings and 3%, 6%, 9%, 13%, and 18% for the asphalt emulsion, obtaining favorable results in the subgrade in accordance with the CE.010 Urban Pavement standard. With the steel filings the CBR (California Bearing Ratio) had a linear increase whose maximum value was reached with the dosage of 15% increasing the CBR considerably by 189.47% above the CBR of the natural soil; on the other hand, with the asphalt emulsion a maximum increase in CBR was obtained with the dosage of 13% obtaining an increase of 236.84% and after that a decrease is observed with the addition of 18% of asphalt emulsion.
