摘要：The roughness index is a function of the smoothness of the pavement, comfort and safety to the roaduser. Traditionally the assessment of road roughness has been based on the riding quality measured by an instrumentedcar or other suspension-type response instruments. Such devices are, however, neither time-stable in themselves norconsistent between similar vehicles. It is therefore necessary for their output to be calibrated against a standardroughness scale, such as the profile-based International Roughness Index (IRI).The various equipments available formeasuring roughness are Meter Straight Edge, Dipstick Profiler, Profilographs, Rod and Level Survey and ResponseType Road Roughness Measuring Systems. MERLIN, MWUI, VMBI and FWBI are categorised under RTRRMS. Inthe present study an attempt is made to measure unevenness of pavement using MWUI, Bump integrator - ROMDASequipments for the selected study stretches with varying pavement condition.IRI values from various equipments aredeveloped. The calibrations of these equipments are done using the standard equipment TRL MERLIN. An attempt isalso made to determine the correlation between Present Serviceability Rating and International Roughness Index usingdifferent models.
