PaveScan™- Density Meter

The First Continuous Asphalt Density Measurement System

The InstroTek PaveScan Powered by GSSI Technology is the first non-nuclear rolling density system that provides real-time compaction and density data for the entire paving project. Proper compaction is the most important factor in producing long-lasting pavements. The PaveScan uses multiple sensors to continuously scan the entire pavement and provide a density profile of the entire paving project. The operator pushes the cart along the lane and gathers density data behind the asphalt rollers. The onboard computer displays density, compaction, a line graph, and a contour map of the measurements. This information is used by contractors and pavement engineers to assess the quality of the pavement.   

The Future of Zero Coring is Within Reach

Contractors and State Agencies refer to the PaveScan as The Continuous Coring System! With PaveScan, the possibility of zero coring is within reach. Many pavement failures including potholes start at and around the coring location. This technology has the potential to drastically reduce if not eliminate the need for field cores, saving thousands on coring operations, reduction in traffic delays, and improving work zone safety.  

More is Better

Traditional nuclear and non-nuclear gauges only offer single-point measurements.  The PaveScan can take hundreds of measurements per minute, producing an accurate picture of the entire pavement project. The three-sensor system can cover up to 6 feet across the lane. The wheel encoder, together with the optional GPS, can accurately track the movement of the PaveScan on the roadway. This information can be used with Google Earth for a comprehensive density profile of the entire paving project. The data can be analyzed to determine areas of interest for further investigation.

The Perfect Asphalt Joint

Many pavement failures occur and start at the joints. Therefore, achieving good joint density is key to producing a long-lasting pavement. The PaveScan allows the operator to take density measurements along the entire joint. A single sensor with a green laser guide ensures the sensor is positioned directly over the joint. For the first time, contractors can measure joint compaction consistency throughout the entire project.
