This study was conducted to look into possibilities of the recycling of electronic waste (e-waste) sludge as additive in asphalt concrete mix materials. Specimens of varying compositions of asphalt and e-waste sludge of cathoderay-tube’s (CRT) manufacturing unit were prepared following standard operating procedures. Stability, flow rate, porosity and density of the recycled product were optimized corresponding to Korean Constructional Industry Standards. Performance of mix design specimens was evaluated in accordance with Marshall Properties Test. An optimum value of sludge was determined that could be recycled in asphalt concrete mix without causing damage to the engineering characteristics of the asphalt concrete mix material. Contaminants of heavy metal ions and other toxic chemicals in the leachate of prepared specimens were analyzed and found below permissible limit. Therefore, it was suggested that entire sludge could safely be recycled in asphalt concrete mix materials as additive. Recycled product could successfully be utilized in meeting increasing demands of constructional materials.
