Asphalt

Product Description: Asphalt

Overview

Asphalt, also known as bitumen, is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is widely used in construction for paving roads, roofing, and waterproofing due to its durability, water resistance, and adhesive properties.

Uses

• Paving Roads: Essential for constructing and maintaining roads, highways, and parking lots.

• Roofing: Used in roofing shingles, roll roofing, and flat roof membranes for waterproofing and protection.

• Waterproofing: Provides effective waterproofing for basements, foundations, and other structures.

• Driveways and Pathways: Ideal for residential driveways, walkways, and cycle paths.

• Recreational Surfaces: Utilized in sports courts, playgrounds, and running tracks.

Specifications

• Material Composition: Composed primarily of bitumen, which is a byproduct of crude oil distillation.

• Types: Available in various grades such as hot mix asphalt (HMA), warm mix asphalt (WMA), and cold mix asphalt (CMA), each suited for different temperatures and applications.

• Temperature Range: HMA is typically applied at 275-300°F (135-150°C), WMA at 200-250°F (93-121°C), and CMA can be used at ambient temperatures.

• Durability: High resistance to weathering, heavy traffic, and mechanical stress.

• Flexibility: Retains flexibility under various temperature conditions, reducing the risk of cracking.

• Permeability: Low permeability to water and air, providing excellent waterproofing capabilities.

• Adhesive Properties: Strong adhesion to aggregates, ensuring a stable and durable pavement structure.

• Packaging: Usually supplied in bulk for large projects, and in bags or containers for smaller applications.
