摘要

The purpose of the experimental study was to find the suitability of Electric Arc Furnaces (EAF) slag and Ground Granulated Blast Furnace Slag (GGBFS) in base/sub-base layer of Flexible Pavement. Different trail mixes of EAF slag + Cement and EAF slag +GGBFS were tested to find an optimum mix. The GGBFS proportions were taken 5%, 10%, 15% and 20% of the total dry weight of mix and cement was added 3%, 4% and 5% of total dry weight. The mechanical and chemical properties of mixes were found to check the suitability of the material for the construction of cementitious base/sub-base in low volume road (LVR). The IITPAVE Software was used to find out the pavement thickness with the optimum mix. EAF Slag + 4% cement and EAF slag + 15% GGBFS satisfied the strength criteria of for Rural Road. The strains obtained from the IITPAVE software were in a permissible limit. Further, the results of Toxicity Characteristics Leaching Procedure (TCLP) analysis for various metals show that mixes of EAF Slag and GGBFS were a non-hazardous material. This study supports the use of industrial waste in the construction of low volume road in India.
