Abstract

PrI and IRI, which are the methods of measuring the smoothness of asphalt pavement, were investigated and analyzed. As a result, it was evaluated that it was appropriate to change from the current PrI to IRI to maintain the continuity of maintenance after the initial quality control and subsequent road pavement was constructed, and to increase the convenience of the driver. Accordingly, in order to apply IRI in Korea, IRI measurement and analysis methods and quality standards suitable for Korean characteristics, measurement equipment certification and calibration standards, and measurement manpower training systems must be prepared.
