Investigation of the fatigue characteristics of warm stone matrix asphalt (WSMA) containing electric arc furnace (EAF) steel slag as coarse aggregate and Sasobit as warm mix additive

摘要

On the one hand, several million tons of steel slag is produced annually as the by-product of Received 18 January 2019 the steel industry in Iran and other countries and are deposited in landfills without any use, Received in revised form 20 June 2019 occupy vast areas, and cause environmental hazards. On the other hand, the high mixing Accepted 20 June 2019 temperature of the hot mix asphalt (HMA) increases the emission of greenhouse gases, the cost of fuel, accelerated wear of asphalt plant equipment, and less safety of workers in the.
