The present invention relates to a room-temperature asphalt concrete composition using, as a main raw material, waste asphalt concrete-recycled aggregate, waste concrete-recycled aggregate, waste glass aggregate, and dried waste sludge powder, and the like, which are produced by processing industrial waste to reduce cracks generated in asphalt concrete. According to the present invention, the recycled room-temperature asphalt concrete composition using waste glass aggregate and waste sludge comprises: 48 to 63 wt% of waste asphalt concrete-recycled aggregate with a particle size of 8 to 30 mm; 6 to 14 wt% of waste concrete-recycled aggregate with a particle size 8 to 30 mm; 10 to 20 wt% of waste glass powder with a particle size of 8 mm or less; 1 to 15 wt% of blast furnace slag fine powder; 1 to 15 wt% of high-calcium fly ash; 1 to 5 wt% of dried waste sludge powder; 1 to 5 wt% of paper sludge incineration ash; 1.5 to 2.5 wt% of emulsified asphalt; 0.1 to 0.4 wt% of a regeneration additive; and 2.1 to 3.4 wt% of water. 본 발명은 산업폐기물을 가공하여 생산한 폐아스콘 순환골재, 폐콘크리트 순환골재, 폐유리 골재, 폐슬러지 건조 분말 등을 주 원료로 활용하는 상온 아스콘 조성물에 관한 것이다. 본 발명은 「입경 8~30㎜ 폐아스콘 순환골재 48~63wt%; 입경 8~30㎜ 폐콘크리트 순환골재 6~14wt%; 입경 8㎜ 이하 폐유리 분말 10~20wt%; 고로슬래그 미분말 1~15wt%; 고칼슘 플라이애시 1~15wt%; 폐슬러지 건조 분말 1~5t%; 제지슬러지 소각재 1~5wt%; 유화 아스팔트 1.5~2.5wt%; 재생첨가제 0.1~0.4wt% 및 물 2.1~3.4wt%를 포함하여 조성된 순환 상온 아스콘 조성물」을 제공한다.
