Definition of Road or Pavement
Pavement or Road is an open, generally public way for the passage of vehicles, people, and animals.
Pavement is Finished with a hard smooth surface. It helped make them durable and able to withstand traffic and the environment. They have a life span of between 20 – 30 years.
Road pavements deteriorate over time due to
- The impact of traffic, particularly heavy vehicles.
- Environmental factors such as weather, pollution.
Many people rely on paved roads to move themselves and their products rapidly and reliably.
- One of the primary functions is load distribution. It can be characterized by the tire loads, tire configurations, repetition of loads, distribution of traffic across the pavement, and vehicle speed.
- Pavement material and geometric design can affect quick and efficient drainage. This eliminating moisture problems such as mud and ponding (puddles). Drainage system consists of:
- Surface drainage : Removing all water present on the pavement surface, sloping, chambers, and kerbs.
- Subsurface drainage : Removing water that seep into or is contained in the underlying sub-grade.
