Sažetak
The thickness of the pavement structure layers represents an important data for implementation into the database of roads already constructed, during designing of the pavement strengthening, particularly if the appraisal of the bearing capacity of the pavement structure is done by means of the Falling Weight Deflectometer, during reconstruction of pavements or during control of the newly-constructed roads. If reconstruction is carried out by procedures of recycling of the existing pavement, the details about the thickness of asphalt layers are important not only during determining the depth of the intervention, but also during designing of the asphalt mixture. During quality control of newly-constructed road sections, GPR can be used as the means for fast and efficient determining of the thickness of layers. Measuring is done at speeds which approximately correspond to speeds of the traffic flow, so that disturbance of traffic is minimum, whereby the safety of participants in traffic and measuring personnel is increased. The paper presents several examples of determining the thickness of layers of road pavement structures, by the non-destructive GPR method. The obtained results were compared with conventional methods of determining thicknesses which are used in Croatia, which are coring or data obtained by surveying methods during constructing of the pavement structure layers. Measurements were done on completely new and existing roads of different age with the asphalt final layer.
