Three of the essential elements of constructing a long-lasting asphalt driveway or parking lot are subgrade preparation, drainage and pavement thickness design. For rigid pavements, the initial pavement structure shall be designed and analyzed for a performance period of 30 yr. A performance period other than 30 yr. may be utilized with justifications. Its lack of repetitive joints removes the possibility of the blowups that The long-term performance of a flexible pavement depends upon each of the layers, from the subgrade surface up, being of higher quality than the layer on the supporting medium.
