• Abstract:
  In recent years, the Texas Department of Transportation has made significant progress with the ; development and implementation of new technologies to measure the uniformity of new hot mix asphalt ; layer construction. Early studies focused on the development of the Pave-IR system for checking ; temperature uniformity during mat placement. In Project 0-6992, researchers took this check one step ; further by developing an accurate global positioning system tracking system for compaction rolling so that ; the compaction effort applied can be monitored for 100 percent of the new surface. ; Additional sensors were also included in the system, including two temperature sensors and an ; accelerometer, to monitor whether the roller is vibrating. The new system can be mounted on any roller in ; a matter of minutes, and it provides the roller operator with real-time color displays of: The number of passes of the entire mat; The compaction effectiveness (this study found that better compaction was found directly ; under the center portion of the roller than at the roller edges); The temperature at the first pass of the roller. ; This report presents details of the hardware and software developed in this study. The system was field ; tested on a number of new overlay projects in Texas. Those results will be reported in later reports from ; this study.
