Properties and Applications of Asphalt

Asphalt, also known as bitumen, is a black, sticky petroleum product used in various applications due to its viscoelastic properties. Historically, it served as a waterproofing and adhesive agent in ancient civilizations like the Indus Valley and Egypt. Today, asphalt is primarily used in road construction, forming asphalt concrete with aggregates. Mastic asphalt, with higher asphalt content, is used for waterproofing. Asphalt can also be emulsified for low-temperature applications, aiding in cost-effective pavement solutions.
