What Is Road Pavement?
Road pavement is a hard surface covered with concrete or asphalt. The surface of the pavement is made of durable material. The purpose of a pavement is to carry vehicle or foot traffic.
Road pavement should have adequate skid resistance and proper ride quality. It should also have favorable light-reflecting characteristics and low noise pollution etc.
Pavements are used in various places such as roads, runways, parking areas, etc. Land transport is used for most transportation in the world. This is why pavements should be properly designed for construction. And it should be strong and durable for his life.
The number of vehicles, speed of vehicles, climatic conditions, and other factors should be taken into consideration while designing the pavement.
The Function of Road Pavement
The main function of a pavement is to survive without being distorted by loads applied by heavy vehicles such as heavy trucks or aircraft. Water is harmful to the pavement. Water damages its surface by chemical reaction with the pavement. Adequate drainage is provided when constructing the pavement.
The primary function of the pavement is to transmit the vehicle load to the sub-base and the underlying soil. Modern, flexible pavements are composed of sand and gravel or crushed stone. This material is well compacted with binder materials such as bitumen, tar or tar, or bitumen oil. In addition, the pavement has plasticity-like properties to absorb shocks.
