A rural principal arterial is expected to carry an ESAL of 0.188×106 during the first year of operation with an expected annual growth of 6% over the 20-year design life. If the subgrade has resilient modulus of 15,000 psi, design a suitable pavement consisting of a granular subbase with a layer coefficient of 0.13, a granular base layer with a layer coefficient of 0.14, and an asphalt concrete surface with an elastic modulus of 400,000 psi. Assume all m; values = 1 and the percent of traffic on the design lane is 47%. Use reliability level of 99%, standard deviation of 0.4, and APSI of 2.0. If the minimum required thickness of asphalt surface and aggregate base course is used, what is the design thickness of subbase?

Pavement Management

Pavement management is the process of planning the maintenance and repair of a roadway network or other paved infrastructure to improve road conditions throughout the network. It is also used on runways and airports. Every highway superintendent undertakes walkway management. Traffic management includes the cost of living cycles in a systematic way of repairing minor and major roads and reconstruction projects. The needs of the entire network and budget estimates are considered before the projects are undertaken, as the cost of data collection can change significantly. Pavement management incorporates many of the features and functions required to maintain the quality of the paved material as well as to ensure that the entire road network can sustain itself at the required levels. Although pedestrian management involves the life cycle of commuting from planning to maintenance of any transport infrastructure, road asset management, and road maintenance planning is primarily aimed at road infrastructure.
