Abstract:
State Transportation Agencies (STAs) use quality control/quality assurance (QC/QA) specifications to guide the testing and inspection of

road pavement construction. Although failed materials of pavement rarely occur in practice, it is critical to have a sound decision

framework to assist in making data-driven, informed decisions regarding failed materials because such decisions have profound impacts

on the long-term performance of the pavement and the operation and maintenance costs of the responsible highway agencies.

A performance-related specification (PRS) is a quality acceptance (QA) specification that specifies the acceptable levels of key acceptance

quality characteristics (AQCs) that are directly related to fundamental engineering properties, which in turn, determine the long-term

performance of the constructed end products. Two PRS tools, PaveSpec for Portland Cement Concrete Pavement (PCCP) and Quality

Related Specification Software (QRSS) for QC/QA Hot Mixed Asphalt (HMA) pavement, were investigated in this study to develop

decision frameworks for PCCP and HMA pavement to assist the decision-making regarding failed materials at INDOT. A large number of

simulations of various scenarios in the context of INDOT pavement construction were conducted to fully develop and implement the

decision framework.

For PCCP, the newly developed decision framework based on PaveSpec was validated using data from an INDOT construction project.

The framework is readily implementable to assist INDOT in making informed decision regarding failed materials for PCCP. For QC/QA

pavement, it was found that QRSS is not an appropriate PRS tool to estimate the long-term performance because of its limitations, the

misalignment between QRSS process and INDOT practice, and erroneous simulation results.
