Pavement Marking Retroreflectometer. Pavement markings are one of the single most important infrastructure elements to a roadway's safety; they provide guidance, direction and warning to the motorists and pedestrians that use the roadway system. Retroreflectivity provides motorists with nighttime visibility of these pavement markings.

Levels for Pavement Markings Pavement marking visibility in rainy, nighttime conditions is essential to vehicle passenger safety. Researchers gathered data from existing studies and new wet-night marking visibility tests to identify levels of wet retroreflectivity that will be included in MnDOT standards for wet-reflective pavement markings.
roadway pavement markings. These degradation curves would be used to forecast the performance of pavement markings and to help determine a cost-effective schedule for reapplying them. To accomplish these objectives, this study utilized a vehicle-mounted Laserlux® retroreflectometer to take measurements on approximately 80 test sections throughout
1.1 This test method covers measurement of the retroreflective properties of horizontal pavement marking materials containing retroreflecting beads, such as traffic stripes and surface symbols, using a portable retroreflectometer that can be placed on the road delineation to measure the retroreflection at a prescribed geometry.
The apparatus shall consist of a handheld 30-meter geometry retroreflectometer, such as the Mirolux 30 retroreflectometer or ART Stripemaster retroreflectometer. 620.13.3 Procedure 620.13.3.1 For new pavement markings, measurement of retroreflectivity should be delayed in accordance with EPG 620.12.2.3 .
Ultra 30, Ultra 15, Ultra 30 SE and Ultra 15 SE. The Mirolux Ultra 15 and Mirolux Ultra 30 are pavement retro-reflectometers featuring 1.5° observation angle, 86.5° entrance angle and 1.05° observation angle, 88.76° entrance angle, respectively. Both sport a built-in printer, highly accurate internal GPS and a Wi-Fi data communications ...
Retroreflectivity is a measure of how efficiently the pavement marking returns light from the headlamps back to the driver. In mathematical terms it is a ratio of the reflected luminance to the headlamp illuminance at a certain viewing geometry. Figure A-1 shows a simple illustration of pavement marking retroreflectivity. Figure A-1.
1.1 This test method covers measurement of the retroreflective properties of horizontal pavement marking materials containing retroreflecting beads, such as traffic stripes and surface symbols, using a portable retroreflectometer that can be placed on the road delineation to measure the retroreflection at a prescribed geometry.
Retroreflectometers and light measurement instruments from RoadVista are available for testing retroreflective signs, pavement markings, pavement markers, delineators, sign sheeting, high visibility clothing, headlamps, and transportation lighting. Laserlux® G7 Mobile Retroreflectometer. StripeMaster® Touch Series Handheld Retroreflectometer.
Pavement markings were previously measured at 15-meter geometry, and no simple conversion exists between 15- and 30-meter measurements. Retroreflectometer geometry is described in further detail in ASTM E 1710. Contact TxDOT's Materials Laboratory for a description of approved retroreflectivity measurement devices.
SM2T: StripeMaster™ 2 Touch Pavement Marking Retroreflectometer Full assessment and management of pavement markings The StripeMaster Touch Series™ of handheld pavement marking retroreflectometers provides agencies and contractors with advanced, reliable, efficient, and effective means of assessing this visibility.
Stripemaster II is a 30 m geometry retroreflectometer suited for measuring pavement markings on dry and wet surfaces. Housed in aluminum case, unit incorporates internal printer and capacity to store up to 10,000 data points. At push of button, wheel-mounted unit delivers individual data point, global position, and timestamp simultaneously.
and pavement markings which apply to all roads open to public travel." The opening statements of the MUTCD define the purpose of traffic control devices and the principles for their use. Traffic control devices, including pavement markings, are meant to promote highway safety and efficiency by providing for the orderly movement of all road users.
Pavement Marking Reflectivity Measured pavement marking reflectivity results vary widely depending on the test. These methods can help you see the differences of reflectivity between pavement markings under different conditions. E1710-18 Dry Method This test method measures the dry retroreflective (RL) properties of horizontal pavement marking ...
NEW – LTL3000 retroreflectometer for pavement markings LTL3000 is the first retroreflectometer from DELTA in a new generation of instruments. LTL3000 is intended for users, who need an instrument for less demanding measurement programs, who do not need many features to support the measurements and who want an instrument which is easy to ...
1.1 This test method covers the measurement of the wet retroreflective (R L) properties of horizontal pavement marking materials, such as traffic stripes and road surface symbols, using a portable retroreflectometer that can be placed on or before the road marking to measure the retroreflection at the prescribed geometry.
