    The Use of GPS-Based Distress Mapping to Improve Pavement Management
    Dzwilewski, Peter-Paul; Long, Genevieve; Wade, Monty (2015-06-04)
    Utilizing recent inspection data of portland cement concrete (PCC) pavements at airports and military installations in the United States and Canada, the enhancement of long-term pavement management through Global Positioning Satellite (GPS)-based distress mapping is examined. Specifically, examples of distress pattern identification, improvements to the determination of localized maintenance repair quantities, the process of selecting appropriate rehabilitation methods, and applying identified deficiencies to future construction and repair projects are discussed. Distress pattern identification illustrates how various types of distresses within and across slabs are related to one another, which allows for the isolation of required repairs and leads to more effective maintenance planning. Comparisons between actual repair quantities from the distress mapping process and standard repair quantities from pavement management software are also analyzed. Distress mapping allows maintenance needs to be located and repaired by maintenance crews, and provides more accurate funding requirements for improved planning. It also offers the ability the track the progression of distresses and the effectiveness of repairs over time. Distress mapping also provides greater insight to selecting the proper rehabilitation method. Pavement repair options can be weighed against rehabilitation or reconstruction options to determine what option will yield the best combination of future pavement condition, cost, and operational requirements. In some instances, the existing distresses can assist in modifying current design, construction, or repair methods being employed. With these benefits, distress mapping can improve the pavement condition and reduce the overall funding requirements.
