This research is focused on asphalt pavement condition deterioration progression modeling and computational simulations of uncracked and cracked asphalt pavement-subgrade models. If timely maintenance and rehabilitation are not performed, the pavement damages inflicted by heavy traffic repetitions and environmental impacts may lead to life threatening condition for road users. Billions of dollars are required annually for the maintenance and rehabilitation of road networks. Longitudinal roughness, pavement cracking, potholes, and rutting are the major reasons for rehabilitation of asphalt roads. About 93 percent of 2.6 million miles of paved roads and highways in the United States (U.S.) are surfaced with asphalt. A country's road network is recognized as one of the largest public infrastructure assets. A nation's economy and prosperity depend on an efficient and safe transportation network for public mobility and freight transportation.
