Field evaluation demonstrates continuous thermal and dielectric profiling accurately predicts asphalt density variability across paving projects, indicating improved quality control.

Key Points

To evaluate the integrated application of paver-mounted thermal profiling and dielectric profiling systems as continuous process control tools to monitor asphalt pavement density and uniformity.
Analyzed field data from six national demonstration projects conducted by the Mobile Asphalt Technology Center across diverse climates, mix designs, and paving conditions.
Used paver-mounted thermal profilers (PMTP) to map placement temperatures and post-compaction dielectric profiling systems (DPS) calibrated with gyratory-compacted specimens and roadway cores.
DPS calibration with gyratory-compacted specimens yielded strong correlations with density (R² = 0.97–0.99), while core validation demonstrated root mean square errors of 0.6%–1.5%, bias within ±1%, and project correlations of R² = 0.65–0.92.
Thermal profiling alone detected localized anomalies but could not fully account for density variations, whereas integrating PMTP, DPS, and selective coring accurately identified continuous low-density risk zones.
