Current Practices for the Prioritization of Rehabilitation and Preventive Maintenance of Pavement Projects in Texas
With finite resources and an extensive road network to maintain, state agencies must make optimal and cost-effective decisions to prioritize roadways to receive rehabilitation (RH) and preventive maintenance (PM) treatments. Prioritization methods implemented by state agencies range from a simple ranking of projects based on judgment to comprehensive optimization by mathematical programming models. The Texas Department of Transportation (TxDOT) districts make RH and PM decisions based on data extracted from the Pavement Management Information System (PMIS). Each district uses a combination of approaches that rely significantly on judgment for identifying RH and PM projects. There is a pressing need to develop a simple, comprehensive prioritization method that reflects statewide experience, while it is easy to implement using PMIS data. A statewide survey was developed to obtain the various methods the districts use to make these decisions. The responses obtained suggested that the PMIS data combined with visual inspection are the main tools use to prioritize projects. A computer tool was developed utilizing the information obtained from the survey data. It relies on a prioritization index based on the weights assigned to various distresses, as well as other factors such as traffic levels and structural condition. This computer tool was successfully verified by comparing its output to actual decisions made by TxDOT district personnel.
