Evaluation of Bonus/Penalty Pay Adjustment Systems for HMA and Ride Specifications of Concrete and Asphalt Pavements
Record Type: DOT
Texas Department of Transportation (TxDOT) currently uses a pay adjustment factor (PAF) system for production and placement of hot mix asphalt (HMA) and ride quality of hot mix asphalt concrete (HMAC), and concrete pavements that have been in existence for almost a decade. Current PAFs are not based on expected pavement performance, but rather on historical data reflecting contractors’ capabilities. A meaningful PAF system should be based on expected pavement performance such that the bonuses/penalties can be economically justified. Current PAFs may be skewed, resulting in PAFs that are mostly greater than 1.0. The goal of this research is to address the following objectives: 1) evaluate the validity of PAFs for ride quality, 2) evaluate the validity of PAFs for HMA production, 3) evaluate the validity of PAFs for placement, and 4) modify existing PAFs based on performance considerations. PAFs proposed under the revised framework will incorporate the economic implications associated with superior (or inferior) pavement performance, as they translate to extended (or reduced) pavement service life. A rational system should reflect that the bonuses awarded to the contractors neither exceed the benefits to the highway agency nor the penalties levied from the contractors that fall short of the potential losses incurred by the agency, due to a reduced service life.
