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.

    Automated road repairs, using 3D printing, could save money and vastly reduce disruption, and researchers are already showing it’s possible - Kristina Smith reports It’s the middle of the night, and in the street below a team is busy carrying out repairs to the road surface. But there isn’t a human in sight. A road repair drone has landed at the site of a crack and a 3D asphalt printer is now busy filling in that crack. A group of traffic cone drones have positioned themselves around the repair location

    Winter driving advice is being provided by the Finnish Vaisala transport research group. According to Vaisala, the driver plays a particularly important role in safety with regard to winter conditions. Driving safely in the winter is not only about road maintenance services and the condition of the road. Driver behaviour, speed, and driving style as well as the condition of the vehicle and its tyres play an important role in ensuring a safe journey. For example, awareness of significantly longer stopping di

    Improved surface quality and improved machine design are key trends in the asphalt paving sector, Mike Woof reports There is a big difference in asphalt paving techniques in North America and Europe. In North America, the need to construct long stretches of highway quickly resulted in wide pavers offering high throughput capacity, with compaction equipment then being used to achieve the required density of the various courses. In Europe's highway construction projects, distances tend to be shorter and contr
