Asphalt cement is a thick, black, sticky substance made from refined crude oil. It is primarily used in the construction and maintenance of roads, parking lots, and other surfaces. Its properties allow it to bind together aggregates, such as gravel and sand, creating a durable and weather-resistant material. This material is produced through a process called distillation, where crude oil is heated and separated into different components. Asphalt cement is essential for creating asphalt concrete, which provides a smooth driving surface and helps manage water drainage on roadways.
