At air temperatures, asphalt cement is a very, very thick liquid (highly viscous). When heated, it becomes thinner and easier to use. ... There are three ways to thin it enough to make it mixable—heat it ...
Demand messageOne major downfall of asphalt is the amount of heat it absorbs during daylight hours due to its low solar reflectance value (0.04-0.06). This characteristic means that asphalt can reach temperatures of up to 70°C in the sun, which can cause deformations in the road surface and intensifies the urban heat island effect present in large cities.
