ABSTRACT
Pavement management system (PMS) is defined as “a set of tools or methods that (can) assist decision makers in finding cost-effective strategies for providing, evaluating and maintaining pavements in a serviceable condition” (FHWA, 1989). The goal of a PMS is to optimize the value of the maintenance funds and to provide the highest possible pavement quality with the allocated resources (Wells, 1984). In order to effectively and efficiently manage urban roadway network, the United States (US) Congress approved the Intermodal Surface Transportation Act (ISTEA) in 1991, which called for the involvement of Metropolitan Planning Organizations (MPOs) in the development and implementation of PMS (Sohail, et al., 1996). Since then, many PMS programs such as MicroPaver and StreetSaver® have been implemented in many cities and counties in the US. For instance, StreetSaver® has more than 100 users in the San Francisco BayArea and more than 250 users nationwide and internationally (Schattler et al., 2011), and users are predominantly cities and counties.
