Impact of Upgrading the Distresses Measurement System on Assessed Pavement Network Condition

Pavement management systems rely on accurate distress data (such as rutting and cracking data) for supporting managerial decision. Therefore, it is important to understand how the measurement errors propagate into the processes of the management system and to quantify the associated consequences, such as the misallocation of funds. This study proposes a methodology for evaluating the impact of changes in the pavement distresses measurement system that influence the assessment of the pavement network condition. The proposed methodology was applied to a case study that estimated the impact of migrating from a 5-sensor discrete automated rut measurement system to a continuous system on the assessed condition of the pavement network in Texas. The condition of the pavement network was determined using the models and indices defined in the Texas Department of Transportation Pavement Management Information System. The impact of the measurement errors and associated uncertainties on the pavement management system outputs was quantified simulating the processes involving measured data using Monte Carlo Simulation. The findings from the case study showed that transition from a 5-sensor discrete automated rut measurement system to a continuous one, would result in a significant drop in the network condition score. The quantified change in the assessed pavement network condition provides key information that can be utilized to design strategies that mitigate the apparent increase in deterioration of the highway network. The proposed methodology is general enough to be applied to the analysis of other types of measurement systems, pavement distresses, or infrastructure management systems.
