WJ Launch ZDR 6020 Retroreflectometer Surveying Service

WJ now provide a surveying service utilising a state of the art Dynamic Retroreflectometer designed to measure retroreflectivity levels of all types of road markings. This supporting capability is part of a growing portfolio of innovations delivered by the UK’s leading specialist road marking company.

The ZDR 6020 retroreflectometer has been tested and certificated for the dynamic measurement of the coefficient of retroreflected luminance (night visibility RL) of road markings, independent of driving speed and it provides the same measuring results as a static, portable retroreflectometer.

By means of a bespoke WJ Retro Vehicle, road markings are surveyed at normal traffic speeds, providing an ideal method for covering extensive road networks including motorway and trunk road, whilst ensuring best practice in safety for the operator and other road users.

The measurement of the coefficient of retroreflected luminance RL can be carried out day or night due to the ambient light supervision built within the system.

The ZDR 6020 consists of a measuring head mounted on either side of the vehicle, a connection box and laptop with a separate display touch panel displaying the position of the marking.

The surveyor aligns the vehicle in such a way that the measuring area is always on the marking, continuously measuring retroreflectivity 6metres in front of the head and the data is logged directly into the software file database. The touch panel displays the current measuring value and a representative image of the retroreflection data of the marking. A fully detailed report is provided on completion.

Justin Fischbach, Technical Manager WJ Products Bradford commented “Our easy to understand reports which provide precision data and graphic displays are designed to support highway engineers monitor performance of road markings in line with the relevant requirements and recommendations of TD26/07.”

In addition to retroreflection values of road markings the system has the ability to capture active cats eyes, temperature, humidity, driving speed, GPS- coordinates, pictures and voice notes which are all logged on the file.

The WJ business is dedicated to permanent and temporary road markings and exceptional service delivery for clients is a core value.
