필요시 첨가재료를 넣어서 이를 약 160℃ 이상의 고온으로 가열 혼합한 아스팔트

혼합물을 생산하여 시공하는 것이다.

(2) 중온 아스팔트 콘크리트 포장은 가열 아스팔트 콘크리트 포장 이상의 품질을 유지하면서,

가열 아스팔트 콘크리트 포장에 비하여 생산 및 시공 온도가 약 20℃ 이상 낮게 생산된

(5) 쇄석 매스틱 아스팔트(SMA, Stone Mastic Asphalt) 포장은 골재, 아스팔트,

셀룰로오스 화이버(Cellulose Fiber)로 구성되며, 굵은 골재의 비율을 높이고 아스팔트

함유량을 증가시켜 아스팔트의 접착력은 골재의 탈리를 방지하는 역할을 담당하고,
