20.500.12556/DKUM-91917 Use of Lignin, Waste Tire Rubber, and Waste Glass for Soil Stabilization The complex interactions between soil and additives such as lignin, glass powder, and rubber tires were investigated using principles of material and soil mechanics. Previous research has mainly focused on individual additives in clay soils. In contrast, this study investigates soil improvement with two different types of waste materials simultaneously. The improvement of soil properties by hybrid waste materials was evaluated using several laboratory tests, including the standard Proctor test, the unconfined compressive strength test, the California Bearing Ratio (CBR) test, and cyclic triaxial tests. The aim of this research is to identify key parameters for the design and construction of road pavements and to demonstrate that improving the subgrade with hybrid waste materials contributes significantly to the sustainability of road construction. The mechanical and physical properties were evaluated in detail to determine the optimal mixtures. The results show that the most effective mixture for the combination of waste glass powder and rubber tires contains 20% glass powder and 3% rubber tires, based on the dry weight of the soil. For the combination of waste glass powder and lignin, the optimum mixture consists of 15% glass powder and 15% lignin, based on the dry weight of the soil. These results provide valuable insights into the sustainable use of waste materials for soil stabilization in road construction projects. soil stabilization waste glass tire rubber waste lignin hybrid waste usage mechanical properties pavement structure stabilizacija zemljin odpadno steklo odpadki iz gume uporaba hibridnih odpadkov mehanske lastnosti voziščna konstrukcija true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/applsci © 2024 by the authors Članek v reviji 2025-02-28 08:01:53 2025-02-28 08:01:53 2026-02-13 13:49:59 0000-00-00 00:00:00 2024 0 0 str. 7532 no. 17 Vol. 14 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-08-08 2024-08-23 2024-08-26 624.04 2076-3417 207343875 https://dx.doi.org/10.3390/app14177532 applsci-14-07532.pdf applsci-14-07532.pdf 1 61C55651EC1231F943F96B18869FD022 383de747108b58758812d2a321f9030b1adb1decd438deb2413b1705fd35c8b8 36affce4-f5a4-11ef-a2be-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=188893 https://www.mdpi.com/2076-3417/14/17/7532/pdf 1 e490ed66-f5a1-11ef-a2be-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=188892 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
