Applications
- Network-wide condition survey on all categories of roads
- Inspection/acceptance of new construction and conservation measures
- Documenting evidence of surface attributes prior to special use
- Clarifying circumstances at accident hotspots
- Object-specific assessment of longitudinal and transverse evenness as well as substance characteristics
Measurement system
- Multiple functions: Longitudinal and transverse evenness, substance characteristics, video recordings
- Measurements at high speeds of up to 100 km/h
- Speed-independent operations, hence no traffic-related impacts
- Objective results through metrological instruments rather than manual registration
- Precision thanks to high resolution laser measurements and digital video technology
- Self-securing according to DIN 30 710 and HSM 2000
Purpose of condition survey and evaluation with ARGUS®
- Provision of network-wide condition data as an objective basis for decisions concerning short-, medium- and long-term conservation
- Optimized use of increasingly limited resources
- Basis for transparent decisions within and outside building administration departments
- Monitoring the effectiveness of measures and impact of delays in measures
- Forecasting future network conditions
- Practical insights into the success/failure of types of measures and building material concepts used for conservation
Surveyed parameters
- Longitudinal evenness (IRI, AUN, NBOI)
- Transverse evenness (rut depth, water depth)
- Surface distress (cracks, patches, potholes, ...)
- Right-of-Way and road surface images
- Macro texture
Localization and orientation system
- Satellite navigation system DGPS (differential global positioning system) with a typical accuracy of +3 m in real time and +1 m in post-processing
- Use of a high-precision, fibre-optic gyro for determining locations on routes on an occurrence of GPS shadows
- Assignment to the nationwide network node system using raw geo-grids via WGS 84 coordinates
- Measurement of distance by means of pulse generators with a path resolution of 1 mm
- Keyboard input by the operator during measurements
Evaluation of measurement results
- According to the regulations of the Road and Transportation Research Association (Forschungsgesellschaft für Straßen- und Verkehrswesen (FGSV))
- Taking into account specific regional characteristics and the client's individual interests wherever necessary
Representation of measurement results
- Summary of results in a road database using the STRADIVARI® analysis and visualization software
- In tabular and/or cartographic form
- Video image digitization and creation of a video image database with route images on data media
- Creation of raw data files (raw geo-data)
