• Abstract:
  This project conducted work to complement implementation of Pave-IR into the Texas Department of ; Transportation’s hot-mix-asphalt quality control/quality assurance specification. Pave-IR provides real-time ; thermal profiling of paving operations to detect thermal segregation. To facilitate this implementation, a ; webinar was first conducted to introduce industry and agency personnel to the background of thermal ; profiling and how thermal segregation relates to mixture properties and performance. More than 80 ; attendees comprising both contractor and agency personnel attended the webinar. The webinar materials are ; available separate of this report as Product 5-4577-05-P1. Next, Pave-IR thermal profiling was demonstrated ; on eight construction projects. This report presents the results from these demonstrations, which were made ; of varying mixture types around the state. The thermal profiles collected ranged from projects with little ; thermal segregation to projects with frequent severe thermal segregation. In all cases, the demonstrations ; revealed contractor and agency staff eager to learn more about the technology and how the results can be ; used to place higher quality asphalt mixtures.
