Asphalt exists in two primary states: it remains solid at ambient temperatures and transitions into a liquid when heated.

In construction, laborers heat the asphalt to its liquid form and apply it onto the work surface. Upon cooling, it solidifies into a protective coating, enhancing waterproofing, commonly employed in roadway construction and roofing applications.
