Pavement management system or PMS is a term that relates to a system that utilizes the condition coding of roadways coupled with the identification of strategies to determine maintenance or re-construction activities. The definition for pavement management system is "a system which involves the identification of optimum strategies at various management levels and maintains pavements at an adequate level of serviceability. These include, but are not limited to, systematic procedures for scheduling maintenance and rehabilitation activities based on optimization of benefits and minimization of costs."[1]
A pavement management system contains a series of decision units used to determine how and when to repair the roads surface based on various tests. These tests can be simply visual or employ special software and databases to provide rankings for roads or road sections. "The State of California was among the first to adopt a (PMS) in 1979. Like others of its era, the first PMS was based in a mainframe computer and contained provisions for an extensive database.[2]
Pavement management systems are now used in all 50 states as well as other countries worldwide in order to efficiently manage the maintenance of paved roadway surfaces.
