What we do:
Comprehensive road diagnostics for the Road Data Bank of the Czech Board of Roads and
Freeways as an input for the so-called “Expert Road Network Management System”
Measurements of the quality of surface properties of newly built roads and freeways for
investors and contractors
Specialised measurements for court experts, focusing on the effects of road irregularities on
road safety
Land survey for the so-called digital road models with design accuracy
Generate digital road maps and stabilise “nodal benchmarks” in the WGS 84 and JTSK
systems !!! A unique achievement in the history of road management !!! See news –
interesting also for entities active in the field of land surveying and cartography, particularly
for creating digital photogrametric orthophotomaps.
Advisory services and expert studies in the field of road diagnostics, surface properties of
roads and expert systems for road grid management, application of the GPS land survey
method, generating GIS.
Land survey for the needs of GIS
Evaluations of technical conditions of the road grid or its parts using our own HDM-4 licence
and measured variable parameters which the system regards as dominant – the rut depth,
the coefficient of longitudinal irregularity IRI, surface macro-texture and road
surface distresses (cracks, rawelling, potholes). From these parameters we determine the
need for further measurements of the remaining parameters such as anti-skid properties and
load-bearing capacity, to be performed by subcontractors. Using this program, we also
assess the effects of unsuitable road alignment parameters. These parameters are
measured in the same fashion as the mentioned variable parameters in a single run of the
ARAN diagnostic vehicle, driving at a speed of between 50 and 90 km/h.
A comprehensive road database and its maintenance, including auxiliary services for the
needs of road management administrative bodies, particularly for the newly established
“higher regional units”
A comprehensive input for a qualified evaluation of newly built roads includes:
Diagnostics of road surface quality
Diagnostics of airport apron surface quality
Measurements of the rut depth
Measurements of cross-sectional irregularities and compliance with the designed cross-
section of newly resurfaced bitumen, bitumen-concrete and concrete roads
Measurements of the road longitudinal profile at 20 cm intervals
Measurements of the road surface macro-texture
Detailed measurements of the depth, shape and configuration of the abrasive layer granules
Making high-quality video-recordings of road surfaces, the condition of technical fittings and
visibility ranges Classification of cracks, rawelling, blisters, potholes, bumps and other road damages
Accurate location of all measured parameters and damages
Simultaneous measurements of all parameters
Daily coverage 100 km, results available immediately
Graphic representation of the results, digital video recording and storage of data on memory
media
Freeways as an input for the so-called “Expert Road Network Management System”
