What does PSPA mean in UNCLASSIFIED

The PSPA provides quick and accurate assessments of pavement condition that can help detect potential safety hazards in road surfaces, minimize maintenance costs, and optimize efficiency in construction projects.

The PSPA utilizes a small, lightweight probe that is placed onto the pavement surface, releasing controlled acoustic waves into the asphalt. This produces seismic data analyzed by sophisticated software to provide detailed information about subsurface characteristics, such as particle size distribution and compaction quality.

The PSPA collects seismic data from the acoustic vibration of the pavement surface, which is then analyzed using advanced software to generate detailed reports on subsurface characteristics like shear wave velocity and modulus depth profiles. These reports can be used to identify areas where repairs are needed or improvements can be made for optimized performance on roadways.

The PSPA is capable of testing any type of asphalt or concrete surface including roads, parking lots, and airport runways. It's also capable of testing multiple layers simultaneously to identify potential weak spots in pavements due to aging, cracking, or deformation.

Yes! The PSPS system is user-friendly as it has been designed with an intuitive user interface. It comes with on-site training so operators can quickly get up to speed on how to utilize all its features quickly and accurately obtain results they need fast - even in harsh environments such as dusty or noisy locations.
