The nature of the asphalt pavement is highly regarded for its excellent waterproofing, flexibility, and adhesive properties to bind and hold aggregates in the pavement under punishing traffic and weather demands. Which is why asphalt has been used extensively for paving and road construction.

The strength of asphalt pavement is directly related to the pavement design from the ground up. The asphalt pavement people see is only the "roof," so to speak, of the entire pavement. This "roof" covers a bed of graded stone aggregates of varying depths according to ground conditions as well as traffic requirements. This base of aggregate is what really carries the load of the traffic.
