CONSTRUCTION USE OF VITRIFIED CHROMIUM-CONTAMINATED SOILS
This paper describes test results of a demonstration study on the use of vitrified soils as highway construction aggregates. It is based on a bench- and pilot-scale feasibility study of the remediation of chromium-contaminated soils (CCS) through cold top ex situ vitrification, making glass from wastes. To determine the suitability as construction aggregate, vitrified soils were subjected to several tests. Test results were compared with New Jersey DOT and ASTM specifications for construction aggregates. Results showed that the vitrified soils could be accepted as an aggregate material. The vitrified CCS were also used as aggregate in hot mix asphalt (HMA). Mix designs were performed to determine the maximum amount of vitrified CCS that can be added to make acceptable HMA concrete mixes. These tests showed that it is possible to include up to 58.8% of vitrified CCS in HMA mixes. The Marshall test, durability test, and hydraulic conductivity test were performed to evaluate the performance of HMA made with vitrified CCS. HMA concrete mixes made with vitrified soils performed well, indicating their suitability in construction.
