Retro Reflectometer for Road Marking Line
Retro Reflectometer for Road Marking Line
I. Overview
Retro-Reflection Meter For Road Marking is a professional measuring instrument used to measure the reflectivity of road markings. The measured parameters are the retroreflective coefficient R'or the specific brightness of the marking line in mcd. lx-1. m-2. The instrument is simple to operate and reliable in measurement. It can be used not only in laboratory environment, but also in field measurement. It is an optimum instrument for measuring the reverse reflection performance of pavement markings, such as production, quality supervision, engineering construction and supervision units.
II. Main Functional Characteristics and Technical Parameters
1. Product Basis and Standards
The instrument is designed and developed with reference to relevant international technical documents and current national standards and norms in China. It meets the requirements of No. 72 published by the International Lighting Commission (CIE), ASTM D4061-94, DIN67520, 67521 of Germany, GB/T 26377-2010 Reverse Reflectometer of China, GB/T 16311-2009 Quality Requirements and Monitoring Methods of Road Traffic Markings, JJG 059-2004 Verification Regulations of Reverse Reflectometer.
2. Measurement principle
The geometric condition of the retroreflective marking instrument is to simulate the scene observed by the driver in the cab when the headlamp illuminates the marking made of the retroreflective material on the road at night.
The angle between the optical axis of the headlamp and the normal line of the road surface (reference axis) becomes the incident angle (beta), which is set at 88.76 degrees. The angle between the optical axis of the headlamp and the reverse light is called the observation angle (alpha), which is set at 1.05 degrees. The light source and optical system are projected to the marking line according to the incident angle beta. The size of the measured marking line is 200 X 95 mm. The reflected light from the marking line is emitted to the filter equipped with V(lambda) according to the observation angle alpha of 1.05 degree. The measured value is displayed on the measuring value display after processing, that is, the measured value of the inverse reflection coefficient R'.
3. Main parameters
The observation angle of the instrument is alpha=1.05 degrees, the incident angle is beta=88.76 degrees and the complementary angle is 1.24 degrees.
Light Source Color Temperature is 2856K+50K (CIEA Light Source)
The detector is a silicon diode + V (lambda) rectifier, which meets the requirements of CIE standard spectrophotometric observer spectral optical efficiency V (lambda).
The measurement range of L retroreflective coefficient R'is 0-3000 MCD lx-1 m-2
