Sonar Roughness Profiling System (SRPS) that can be used in the construction site was developed and verification tests were conducted to evaluate the applicability of SRPS. Firstly, in the indoor test, objective was to study the ability of sonar sensors. It was tested to check the effect of different shapes and turbidity using five specimens. It was found that the sensors had an accuracy of 1 mm. Plus, it was not greatly affected by the change of the shapes and turbidity. Secondly, in order to confirm field application of SRPS, tests were carried out on site. Although some problems were found, test was completed properly according to test procedure. Based on the test results, it was confirmed that SRPS could be used to measure socket roughness on site where shaft were drilled in rock.
