TxDOT Guidelines to Assign PMIS Treatment Levels

This report has been developed to provide Texas Department of Transportation (TxDOT) with guidelines to assign Pavement Management Information System (PMIS) treatment levels for asphalt and rigid pavements which include Preventive Maintenance (PM), Light Rehabilitation (LRhb), Medium Rehabilitation (MRhb), and Heavy Rehabilitation (HRhb). The treatment level definitions were presented as well as their respective construction projects and frequency of use by TxDOT. The work treatments were defined with focus on the description, conditions for use, advantages, limitations, and expected performance. A decision-support matrix is also included for asphalt and concrete pavements with the aim of identifying the best treatment, based on the severity of existing distresses, traffic levels, functionality of the road, and extent of surface imperfections. In the case of asphalt pavements, an approach was presented to include available structural indices in the network-level decision making process.
