Developing a Quality Measure for Evaluating the Contractor Performance in Asphalt Pavement Construction

Most construction agencies have a quality management system to control and manage the quality of their final product. Once the project is over, the tests results are usually kept in archives with no use. Project bidding is a time when the quality information could be very helpful to identify qualified contractors. The proposed model is an effort to use quality tests in evaluating the contractor performance. The composite percent defective is proposed as the quality measure which combines percent defectives of a number of selected quality characteristics. The trend analysis is used to provide a better look at the contractor performance. The significance of the proposed measure is in its ability to reflect the true quality of the contractor work being calculated based on actual tests results.
