DELTA's portable LTL-X Retrometer for measuring the retroreflection of road markings
199 Delta, which has introduced its brand new handheld RetroSign GR3 retroreflectometer for measuring the retroreflection of traffic signs, also offers a number of instruments for road markings.
The Danish company points out that as the median age of the average driver grows the importance of night-time visibility of pavement markings for traffic safety becomes even greater.

"Night-time visibility is determined by the retroflectivity of the pavement markings and therefore retroreflectivity is an important performance feature built into the roadways and is essential for efficient traffic flow and highway safety," says DELTA.

Its portable LTL-X Retrometer, for example, measures the retroreflection of road markings at a simulated distance of 30m according to CEN (European Committee for Standardisation) and ASTM (3930 American Society for Testing and Materials) standards.

The LTL-X has advanced new technology and an ergonomic design, and is the fourth generation retrometer based on the proven knowledge from the worldwide use of LTL2000 and its predecessors.

The retractable handle has an integrated display, and measurements and settings of road and user ID, line type, measurement averages, instrument status and languages are done at the touch of a button. Optional GPS values are shown, and the LTL-X is fitted with printer and wheels for easier operation.

    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

This is of key importance to contractors running mixed fleets, as data transfer from equipment will now be much easier. This progress has come with a new construction equipment telematics standard from the Association of Equipment Manufacturers (AEM) and Association of Equipment Management Professionals (AEMP). This has added key features to allow data gathering, and a test da

    Jason Barnes reviews the last few decades and the future of tolling technology. Tolling and charging technology has evolved significantly over the last three decades and that evolution is perhaps best illustrated by reductions in or complete removal of impedances to physical progress. Once, it was customary for a driver to pull up to a barrier, make some form of cash payment to a human operative in a booth, and then wait for the barrier to be raised before proceeding. Humans were eventually complemented and
