2021-1-20  Curing of cold mix asphalt Conventional HMA attains its full strength within 24 h of construction whereas CMA (prepared using bitumen emulsion) requires additional time to achieve its full strength. The time required by CMA to achieve its full strength is called curing time of CMA. During the curing process, water present in cold mix evaporates.
