Tar is a thick, dark, sticky substance that is often used in road construction and repair. It is a result of heating coal or petroleum and is used to bind materials together, such as in asphalt for paving roads. Tar is also used in roofing and waterproofing. It has a strong, unpleasant odor and can be harmful if not handled carefully. Because of its adhesive nature, tar helps create smooth, durable surfaces for vehicles to drive on, making roads safer and more stable.
