Physical, microstructure and leaching assessments for pavement road base containing mixed steel slag and cathode ray tube glass

Based on the Toxicity Characteristic Leaching Procedure, element concentration release limits were determined. The results show that the alternative recycled materials are safe for use in aggregates and meet the requirements for natural aggregates used for similar purposes. According to a microstructure analysis, the steel slag is more porous and rougher than granite and cathode ray tube glass. Both the soaked and unsoaked samples show higher California bearing ratio test results. Slag content rises produce higher California bearing ratio test results. The leached barium and lead content is higher than that of the other components, but it is still less than 1% of the TCLP maximum, so the leached elements' concentration does not pose an environmental risk. The laboratory test results have shown that mixtures made up of granite, steel slag, and cathode ray tube glass are both environmentally safe and suitable for use as aggregate in pavement road base.
