Measuring night and day visibility of road markings

The LTL-XL from DELTA: built in modules

Box International studies have proven that relatively more accidents and fatalities happen during night-time driving compared to day-time driving.

At the end of 2008, Danish company 199 Delta launched its latest model, the LTL-XL, a fourth generation portable retrometer for measuring night and day-time visibility of all types of road markings.

"Measures are traceable to PTB (3998 Physikalisch-Technische Bundesanstalt), Germany and NIST (National Institute of Standards), USA. LTL-XL measures according to the international standards EN1436 and ASTM E-1710," says DELTA.

Its LTL-XL offers several new features compared to previous instruments from DELTA and these include the measuring of the ambient temperature and humidity; geotagging using GPS mapping software; USB connectivity and seamless connection to any system using a Web browser.The new equipment is offered with a new coloured display, single-handed operation and single touch controls, which makes the operator's work much easier.

Using LED technology, which makes the instrument almost maintenance free, LTL-XL allows users to work efficiently with measuring times of 1-3 seconds and a large memory of more than 200,000 measurements.

"LTL-XL is built in modules to allow the operator to design the instrument according to actual needs. It comes in a base model to which can be added wheels and telescopic handle, GPS and printer," says DELTA.

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.”

    Road markings as a simple yet extremely effective method of guiding motorists safely on the world's road. Patrick Smith reports. Road markings are as important as road signs and give information about the roads being travelled on and actions that drivers should or should not be taking. For example, in many instances white lines often tell motorists something about the road: longitudinal lines can warn of situations that require action such as turn right, left or do not cross. Transverse lines often mean giv

Project specifications will give detailed criteria of what is required, and companies will either ask outside laboratories to make sure the material meets the specs, or will often carry out such tests themselves with trained staff in an on-site laboratory. This will be equipped with the
