Delta said that the GRX is replacing its previous hand-held traffic sign retroreflectometers, the GR1 and GR3 that were launched a decade ago.

Similar to its predecessor models, the RetroSign GRX is very easy to calibrate and operate. It adds new features allowing users to carry out a more complete measurement programme, for example, on road traffic signs.

The instrument is offered in three base models: GRX-1, GRX-3 & GRX-7 where the digit in the name tells the number of observation angles being active.

The instrument can be delivered with up to seven entrance angles. This makes the instrument suitable for both field and laboratory use.

RetroSign GRX offers features include automatic colour recognition, picture of sign, background and legend colour retroreflection and contrast, scanning of barcodes and QR codes for asset management, instrument tilt and rotation, as well as US sign library.

The sign library will allow the GRX to instantly tell if a measurement has passed or failed.

All instruments come with all features included but only those purchased will be available to the user. If additional features are required in the future, they can easily be made available according to Delta.

RetroSign GRX comes with a calibration reference calibrated in Delta’s DANAK accredited calibration laboratory and is delivered with a free-of-charge accredited calibration certificate.

    Using geosynthetics for soil reinforcement is highly effective but requires a high quality and trusted geogrid. When it comes to deciding which geogrid is best for a specific project, a number of product parameters must be taken into account. In the design of steep slopes, the most important parameter is the available long term design strength (Pdes). Recently, Colbond has significantly increased this factor for its high performance Enkagrid product, recognised with a newly updated BBA (British Board of Ag

US firm Streb Construction has taken a novel approach to its paving fleet by upgrading a CMI paver built in 1999 to use modern machine control technology. The company bought the CMI SF3302 machine new and this piece of equipment had logged a high number of hours since its purchase. However the company realised that this proven piece of equipment could be made to operate more efficiently and productively, as well as more
