A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation.

is strong enough for the expected number of vehicles in a certain number of years. The input of a calculation is the number expected of vehicles (e.g. 10,000,000) divided in groups (e.g. trucks, vans, cars) and the number of years that the road has to function before the road structure has to be fully renewed (e.g. 20 years).
The given example of 20 years does not mean that there is no maintenance during this period. There is a certain amount of maintenance, but it can be scheduled and is low.
For asphalt, the
Shell pavement design method is often used.
