Pavement Density Profiler (PDP) | Operating Principles and Practical Results

The Pavement Density Profiler (PDP) instrument addresses the need to acquire density measurements of a large area quickly, in a non-invasive manner with timely results.
The PDP provides continuous profile capability that allows the variability of the asphalt pavement to be assessed over a complete area. Areas of high and low density can then be targeted for further investigation or corrective action.
The PDP works by transmitting a radio wave signal towards the ground surface and detects the reflected wave, measuring the electrical characteristic of the asphalt. The electrical information is then transformed to density for real-time, in-field results.
