What is tarmac road?

• Tarmac road is a type of road surface, also known as asphalt or blacktop.
• It is made of a mixture of bitumen (a sticky, black, tar-like substance) and aggregates (small stones or sand).
• Tarmac road is widely used for roads, highways, parking lots, and driveways due to its durability, easy maintenance, and low cost.
• Tarmac road provides a smooth, hard-wearing surface that withstands heavy traffic, weather, and wear and tear.
• It is also relatively easy to repair or resurface tarmac road when it becomes damaged or worn.
• However, tarmac road can be slippery when wet or icy, and it tends to absorb heat and emit pollutants, which can contribute to urban heat islands and air pollution.
• To maintain and improve the quality and sustainability of tarmac road, various technologies and practices are being developed, such as recycled materials, permeable pavements, and smart sensors for monitoring and control.
