In-situ measurement of photometric characteristics of street pavement
Energy Efficiency and Indoor Climate
| Measurement | Reflection characteristic of street pavement: Level of mirroring S, mirroring factor κP and luminance coefficients q0, qd thereby classification of the R class and C class |
| Standards | DIN EN 13201, CIE 144:2001 |
| Measurement object | Measurement of street pavement layers on site |
Technical data
| Light source | Actively controllable luminance screen to provide the necessary diffuse and direct light components |
| Sensor system | Luminance meter grade A |
| Measuring angle | Measuring the street pavement at 1° and 2.29° |
Special features
| On-site measurement | On-site measurement of built in street pavement avoiding core abstractions and artificial aging of samples |
| Time-efficient measurement | Compact, lightweight device Automatic control of the measurement |
