Paving is a process of laying down a hard surface, such as asphalt or concrete, to create a road or path. CEMENT is a key component in paving, as it binds the other materials together and provides strength and stability. TAR is also used in paving, as it helps to waterproof the surface and protect it from the elements. Together, CEMENT and TAR are essential components of paving, providing the necessary strength and protection for a durable and long-lasting surface.
