Road construction bitumen is a versatile, petroleum-based binder used in the production of asphalt concrete for paving roads, highways, and runways. Known for its excellent adhesion, waterproofing, and weather resistance, bitumen ensures long-lasting flexibility and load-bearing strength. Available in various grades such as 80/100, 60/70, and polymer-modified types, it enhances surface durability and reduces cracking under heavy traffic and extreme temperatures.
