The present invention relates to an eco-friendly low-carbon rejuvenation additive, including: 50-70 parts by weight of ethylene vinyl acetate (EVA) as a synthetic resin having flexibility; 5-10 parts by weight of ethylene propylene rubber (EPDM) as synthetic rubber; 5-15 parts by weight of acryl rubber as synthetic resin; 10-20 parts by weight of styrene ethylene butylene styrene (SEBS) as a rubber modifier; and 3-5 parts by weight of modified silicone oil as an additive for spraying. The additive is prepared as a pellet-type rejuvenation additive through the extrusion under heating. The additive uses process oil free from aromatic ingredients, reduces the melting point of asphalt to prevent rapid oxidation and aging caused by high-temperature melting, inhibits generation of harmful gases upon the mixing with a regenerated recycled aggregate material to ensure the safety of workers, and minimizes environmental pollution. 본 발명은 친환경 저탄소 중온화 첨가제에 관한 것으로, 유연성을 가진 합성수지로, 50~70 중량부로 이루어진 에틸렌 비닐아세테이트(EVA); 5~10 중량부로, 합성고무로 이루어진 에틸렌프로필렌고무(EPDM); 합성고무로, 5~15 중량부로 이루어진 아크릴고무; 고무 개질제로, 10~20 중량부로 이루어진 스틸렌 에틸렌 부틸렌 스틸렌(SEBS); 및 분사용 첨가제로, 3~5 중량부로 이루어진 변성실리콘오일; 를 포함하여 이루어지되, 가열하면서 압출하여 펠릿타입의 중온화 첨가제로 제조되는 것을 기술적 특징으로 하여 아로마틱 성분이 제거된 프로세스 오일이 사용되고, 아스팔트의 용융점을 낮춰 고온용융에 따른 급격한 산화 및 노화현상을 방지하며, 재생순환골재와 혼합시 유해가스의 발생이 억제되어 작업자의 안전이 보장됨과 동시에 환경오염을 최소화시킬 수 있는 효과가 있다.
