What is Tarmac?
Tarmac is a type of road surface material made from a mixture of tar and crushed stones. It is commonly used in the construction of roads, driveways, and parking lots due to its durability and ability to withstand heavy traffic.
Composition of Tarmac
Tarmac is typically made from a combination of bitumen, which is a sticky black substance derived from crude oil, and aggregate materials such as crushed rocks, sand, and gravel. This mixture is heated and then laid down on a prepared surface to create a smooth and solid road surface.
Benefits of Tarmac
- Durability: Tarmac is known for its durability and ability to withstand heavy traffic.
- Weather Resistant: Tarmac is weather-resistant and can withstand extreme temperatures and conditions.
- Cost-Effective: Tarmac is a cost-effective road surface material compared to alternatives such as concrete.
Examples of Tarmac Usage
Tarmac is commonly used in the construction of highways, airports, and parking lots. It is also used in residential areas for driveways and pathways.
Case Study: Tarmac in Road Construction
In a recent road construction project, tarmac was chosen as the road surface material due to its durability and cost-effectiveness. The project was completed on time and within budget, and the road has since seen increased traffic flow and reduced maintenance costs.
Statistics on Tarmac Usage
According to a recent survey, tarmac is the most commonly used road surface material in the United States, accounting for 85% of all road surfaces. Tarmac is also widely used in Europe and Asia for road construction projects.
