 | Most asphalt pavements are built on an imported gravel base which is generally at least as thick as the asphalt layer, although some 'full depth' pavements are built directly on the native subgrade. |
| Brick, cobblestone and wood plank pavements were once common in urban areas throughout the world, but due to their high manual labor requirements they are typically only maintained for historical reasons. |
| As pavements primarily fail due to fatigue (in a manner similar to metals), the damage done to a pavement increases exponentially with the axle load of the vehicles traveling on it. |

| In theoretical pavement design methods, the material properties determined in the laboratory are used in a model and the long- term behavior of the pavement is forecast based on this model. |
| Standard design curves are given for the thickness of roadbase required to carry the traffic expected to use the road during its design life, life being defined in terms of the timing of pre-emptive pavement strengthening. |
| Pavement structural design, reconstruction and maintenance methods involve the use of theoretical models and varying degrees of experimental verification which should make it possible to adjust the parameters defined in the models and check, on real cases, the assumptions upon which the methods were based. |
