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.
