Abstract:

The Texas Department of Transportation (TxDOT) has been implementing statistically based quality control/quality assurance (QC/QA) specifications for hot mix asphalt concrete pavements since the early 1990s. These specifications have been continuously revised and improved by TxDOT based on feedback and on the results observed during their use. This move towards development and use of QC/QA specifications may lead the way to performance-based specifications (PRS). The pavement performance predicted through prediction models, as well as the relationship between materials and construction (M&C) variables with pavement performance, form the basis for such specifications.

In this report, current performance-based specifications and performance prediction models are discussed. A sensitivity analysis of the prediction model used in this study was conducted and the important influencing factors were ranked. A methodology is presented and a framework is developed on the use of such specifications based on statistical concepts. An approach is developed and presented for determination of payments using PRS and pavement performance. A numerical example is provided on how such an approach could be used to determine payments using the level of reliability on performance of a specific pavement.
