Bituminous materials are a group of substances primarily composed of hydrocarbons, which are derived from the distillation of crude oil. These materials are commonly used in construction and engineering, particularly for paving roads and waterproofing structures. The most well-known types include asphalt and bitumen, which provide durability and resistance to weathering. In addition to their use in road construction, bituminous materials also play a role in roofing and sealing applications. They can be modified with additives to enhance their properties, making them suitable for various environmental conditions. Overall, these materials are essential for infrastructure development and maintenance.
