• Abstract:
  Real-time tests to evaluate asphalt pavement consistency and mat density across the entire width and length of a paving lot are available now and has growing interest for implementation. Two devices that have emerged for use in evaluating the uniformity and density of asphalt mixtures are the paver-mounted thermal profiler (PMTP) and the dielectric profiling system (DPS). Both technologies generate a significant amount of real-time data using hardware and software with spatial referencing sources. A third innovative technology referred to as intelligent compaction (IC) is used to map roller coverage of the mat during construction. The use of these devices has the ability to positively impact pavement performance and are most effective when used in quality control (QC). The purpose of this report is to provide information and suggestions for using intelligent construction equipment in Quality Assurance (QA) programs conforming to 23 CFR part 637, subpart B.
