Road surface assessment with GSSI

GSSI's new PaveScan unit can provide accurate real-time measurements and uncover problems that occur during the paving process, including poor uniformity and significant variations in density. By avoiding these problems, PaveScan RDM helps avoid premature failures from road ravelling, cracking, and deterioration along joints. PaveScan automatically measures the dielectric value to identify anomalies in real-time. In addition, the dielectric values can be used to as a means to correlate voids and density in

GSSI's PaveScan unit
GSSI's new PaveScan unit can provide accurate real-time measurements and uncover problems that occur during the paving process, including poor uniformity and significant variations in density.

By avoiding these problems, PaveScan RDM helps avoid premature failures from road ravelling, cracking, and deterioration along joints. PaveScan automatically measures the dielectric value to identify anomalies in real-time. In addition, the dielectric values can be used to as a means to correlate voids and density in new pavement. The technology enables users to obtain critical density data for QA/QC of new pavements. Unlike other options like nuclear density gauges or radioactive alternatives, PaveScan does not result in any site hazards or require closing off work areas however.

The unit can be integrated with GPS systems and features a versatile, modular design for easy and efficient operation and data collection. It is available as a small, portable single sensor cart-based system or a three-sensor configuration using an extended cart or vehicle configuration.

    Laser scanners and improved data collection and analysis software are making light of asset management surveying. David Arminas reports The age of the laser scanner is upon us, taking over from traditional manual methods of surveying, data collection and processing. These new technical developments are making it much easier to process and use the data captured and are providing highways engineers with powerful tools to record, map and visualise their assets. This is good news for highways authorities

    Rebuilding a runway requires special attention to detail to maximise efficiency and safety Airport runways face special challenges with regard to the loads they carry on a daily basis, particularly when aircraft are landing. A modern jet aircraft will typically land at speeds of around 240-260km/h, with a laden 747 weighing as much as 265tonnes at the end of a long flight. The stresses these large aircraft place on runway surfaces are enormous and not just with the massive impact forces exerted during
