Development and Implementation of Arizona Department of Transportation (ADOT) Pavement Management System (PMS)

Arizona Department of Transportation (ADOT) has been one of the pioneering states in the development and implementation of Pavement Management System (PMS). Since the early 1980's, ADOT has been using pavement management tools to manage, maintain and preserve Arizona's highway network. ADOT's PMS tools were originally based on a probabilistic approach for modeling the pavement performance, which were adequate for the original ADOT requirements. Recently, ADOT has decided to expand the use of the PMS tools to also support the pavement maintenance operations. This required a change in the existing ADOT's PMS tools, which prompted a need to move to a different pavement management software. Subsequently, ADOT selected Stantec's Highway Pavement Management Application (HPMA) software to replace its pavement management system, and retained Stantec's services for structuring, data loading, model development, and implementing the HPMA. HPMA is a single software application that provides full database management and analysis capabilities required by the two types of users (PMS and Maintenance). The HPMA provides capability for users to work at both the detailed highway level and the aggregated section level. Also it provides a wide variety of analysis capabilities, including corrective maintenance, preventive maintenance, and rehabilitation analysis. This report documents the approach used to achieve the goals of this project including the customization of the HPMA to address ADOT requirements, the development of the analysis models, which are based on ADOT historic performance data, and the implementation of these analysis models in conducting a statewide analysis.
