Determine the Effectiveness of TxDOT's HMA QC/QA Bonus Penalty Specification as It Relates to Long-Term Performance

As part of its quality control and quality assurance (QC/QA) process, TxDOT maintains pavement-related data in several databases: mixture design and QC/QA data in SiteManager (SMGR); construction, bid, and project related information in the Design and Construction Information System (DCIS); pavement performance history in the Pavement Management Information System (PMIS); and maintenance activities in Compass or Maintenance Management Information System (MMIS). Even though a significant amount of data and information are available in these databases, the effect of material design factors and QC/QA efforts on the long-term project performance is not well understood. The primary objective of this project is to investigate the relationship between the TxDOT's material design specifications, QC/QA effort, and long-term pavement performance. Researchers will first extract relevant data from TxDOT databases and integrate them into an efficient internal working database for conducting analyses under this research. Various data analysis techniques will be employed to explore relationships between the construction records and pavement performance. Findings from the data analysis will be validated through site visits and discussions with local experts from the TxDOT. Finally, recommendations and modifications will be developed for TxDOT to improve its existing construction practices.
