• 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.
