Asphalt Pavement Scanner and Pavement Density Gauge

The ESS Asphalt Pavement Scanner is a groundbreaking new system that provides unprecedented detail in Q/A and Q/C inspections of new asphalt construction. Surveys can be made continuously at walking speed that keep pace with paving operations. The system has been designed to dovetail into existing workflows from the design phase, to the construction phase, and finishing with the inspection phase. These capabilities are provided by three system configurations: the cart mode, the gauge mode, and the puck calibration mode.  Maps of dielectric, compaction, temperature, and roughness provide a measure of uniformity that cannot be obtained from spot measurements from traditional density gauges. These maps in turn enable better Q/A and Q/C, and ultimately reduced risk and cost.

The Asphalt Density Gauge provides a handheld configuration to measures the pavement’s dielectric constant at specific locations.  Furthermore, the gauge can be used to determine a laboratory grade asphalt mix calibration to convert from dielectric constant to compaction or density.  This is accomplished by measuring the dielectric constant of gyratory compactor pucks.

Contractors can use increased coverage of the APS system to reduce risk and assure their customers that they are providing a quality product. During construction the locations of under compacted zones can be identified while the mat is still warm enough for further compaction. Compaction maps allow contractors to better assess their risk from random inspections from DOTs and owners. Finally, the detailed mapping and reporting abilities provides DOTs and owners assurance that they are receiving a uniform and quality product.
