Encyclopedia
Structural road design aims to ensure the road
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).
