AASHTO PP 98-20 (2021) specifies the equipment and software requirements for a dielectric profiling system (DPS). Calibration and verification procedures are also detailed. A DPS uses ground penetrating radar (GPR) technology to continuously measure asphalt compaction quality up to highway speeds. The DPS system reports the asphalt surface dielectric constant which is strongly correlated to asphalt air void content (FHWA/TX-92/1233-1). As the dielectric constant increases, air void content decreases.
