Description	It is necessary to be careful of geometric accuracy of the roadways when constructing them. Correct thickness of the individual construction layers together with roughness of the pavement belongs among important influences ensuring lifetime of the roadways and vehicles and for comfortable and safe car ride. It is necessary beside other things to have a reliable check measurement method at disposal so as to ensure the required accuracy of the individual construction layers will be achieved. The check measurement method must be able to measure a checked construction component with the required accuracy and with sufficiently high density describing not only global deviations, but also local deviations. The highest requirements on accuracy are placed on the final construction layer of the roadway. Layer thickness and pavement roughness are being evaluated here. The 3D terrestrial scanning method is currently offered for geometric checking of its realization. The article deals with testing of procedure of the pavement roughness measurement with the 3D terrestrial scanning system and with its verification by a total station measurement. Emphasis is put on verification of accuracy of absolute heights of points in the 3D model of the pavement and on size of random errors in the elevation component. Results of the testing clarified using the 3D terrestrial scanning systems and their accuracy for check of the roadway surface.
