Curing of asphalt emulsified tack coat subjected to Malaysian weather conditions

Curing of asphalt emulsions ensures the proper strength development of the material with the evaporation of water. This paper focuses on determining the minimum curing time needed for Malaysian asphalt emulsions. Three factors, including curing conditions (indoor, outdoor, and curing at night), asph...
