Application of Mobile Road Profiler for International Roughness Index Monitoring in Hanoi

An essential element of a pavement management system is a means to monitor pavement surface roughness, distress, and other properties. Most pavement management activities include the use of devices that measure longitudinal profile for assessment of surface roughness. The International Roughness Index (IRI) has become one of the major road roughness indexes that is most commonly used. In Japan, a time-stable and user-friendly compact mobile road profiler (MRP) known as STAMPER II has been developed. This system enables frequent, inexpensive, and regular road surface roughness monitoring. In this paper, some results of the first IRI measurement using STAMPER II in the joint research project between Taisei Rotec Corporation and University of Transport and Communications are introduced. The studies also show the applicability and effectiveness of using mobile road profiler STAMPER II for surface roughness monitoring and pavement management in Vietnam.
