Data collection and Pavement Diagnostics

Data collection of the Central Technical Register of Roads (CTRR) is conditioned by the use of a unified reference network, which is the basic data of the vector model of the road network.

The actual process of collecting most of the data is centralized, i.e. carried out by employees of the Road Data Bank (RDB) department. The collection methodology at the central level is relatively complex and requires a permanent group of professionally trained employees. In pavement diagnostics, centralization is conditioned by the complexity of the operation and the profitability of diagnostic equipment. In terms of personnel and technological capacity, the RDB workplace is built so, that data is collected by these capacities and that it is accessible from the central level to the local level of the road administrators.

Data collection is mostly carried out by devices technologically designed for this purpose using software tools supplied by device manufacturers or specially developed for this purpose within the Information system of the Road Network Model (IS RNM).

The Road Databank Department has modern equipment:

•  For measuring basic data of the reference network and other road inventory 

• Measuring equipment for collecting basic data of the reference network and road inventor

• Mobile mapping system (MMS) - equipment for collecting primary data of roads and roads inventory.

• For pavement diagnostics

•    KUAB FWD 150, 50 - pavement deflection measuring devices

•    PROFILOGRAPH - pavement unevenness measuring device

•    SKIDDOMETER BV 11 – pavement surface longitudinal friction measuring device

•    LINESCAN – pavement surface recording device (evaluation of craks)
