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.

    Early detection of pavement defects and the causes of deterioration is essential for effective maintenance planning, writes Dr Alena Uus* There is a need for optimisation and development of UK highway survey methods that would provide comprehensive information on the surface and subsurface pavement condition and operate at traffic speed, which eliminates the requirement for lane closures. Performance of non-destructive testing (NDT) methods commonly employed in pavement condition surveys can be potent

    Concrete paving is now benefiting from the use of sophisticated machine control tools to deliver accuracy and high-quality surfaces Heavy use of concrete roads and runways over time will reveal any flaws in workmanship, the invasion of water, or the wear from use. Discolouration, scaling, crazing, cracking, or curling will sometimes occur due to a poor ready-mix batch, inadequate curing procedure, subgrade settlement, or improper bonding of the finish layer. Concrete surfaces are generally very durab

    The concrete road paving market continues to develop - Mike Woof reports Concrete road paving technology continues to evolve, with new equipment and techniques coming to market. Although concrete road construction has been used for many years, problems with early generation technologies affected this market segment. The first concrete roads were constructed in sections, which led to problems at joints but these were addressed many years ago with the advent of slipform paving. Concrete roads constructed in t
