DELTA launches its LTL-M

Danish company 199 Delta has launched its new LTL-M mobile retroreflectometer.

The company, a leading supplier of retroreflectometers for road markings and road signs, says that until now hand-held retroreflectometers have been the only instruments accurate enough and accepted for contractual valid measurements of road markings.

However, it points to laboratory and field tests performed by the Swedish Road Research Institute (VTI), which compared the LTL-M, an existing mobile retrometer and using a hand-held instrument as a reference, and showed that the LTL-M measures with an accuracy similar to hand-held retrometers.

"Hand-held instruments have limitations. They provide sample measurements which are not representative for retroreflection measurements of the full length and width of road markings. Hand-held instruments may need costly road closure," says DELTA.

"The LTL-M mobile retroreflectometer is based on a new technology with patent pending. LTL-M offers accuracy in line with hand-held instruments under all driving conditions including bumpy roads and curves, and provides continuous measurement at normal driving speeds in full length and width of road markings combined with checking RRPMs (cat's eyes)." DELTA says the system can be integrated with existing mobile road measurement systems as well as used as a stand-alone unit easily mounted on a car.

    From density tests on a Mongolian gold mine project to an all-singing, all-dancing asphalt tester, Kristina Smith reports on some of the latest new products in materials testing. Perhaps understandably, nuclear density gauges can present contractors with some order to move them at all. “One of the problems with nuclear soil gauges is the restrictions on movement,” said John Lamond, Manufacturing. “If you are a contractor projects cross-border, it’s a real challenge to move a nuclear density gauge around.”

    Machine control technologies are revolutionising construction – Dan Gilkes writes Electronic control of engines, transmissions and hydraulic systems, primarily to reduce exhaust emissions and boost productivity, is also providing manufacturers with an opportunity to incorporate increasingly complex machine control into their equipment. This in turn has the potential to make the machinery more productive, further cutting fuel consumption as part of a virtuous operational circle.
