Abstract
A measurement of roughness as indicator of road network condition – case study Serbia
Highlights
Pavement surface roughness is generally defined as an expression of irregularities in the pavement surface that adversely affect the ride quality of a vehicle
Earlier researches [1,2,3] have established that the measurement of pavement longitudinal roughness expressed through International Roughness Index (IRI) is one of the most important indicators for overall evaluation of road network condition
The pavement roughness data on the 13 191,34 km of the main and regional road network were collected during the period of three consecutive years (2008÷2010) with multifunctional vehicle ARAN
Summary
Pavement surface roughness is generally defined as an expression of irregularities in the pavement surface that adversely affect the ride quality of a vehicle (and the user). Pavement surface roughness represents road profile deformation which highly affects road users. It develops through permanent material deformation in some or all pavement layers, progressively from the moment of road construction. A measurement of roughness as indicator of road network condition – case study Serbia technical - economic evaluation of road projects and analysis of investments in the works on the road network, widely accepted by the International Financial Institutions (IFIs) [6]. The paper examines the existing pavement quality measurement methods, as well as deterioration and prediction models for pavement roughness and their use for the effective evaluation of the overall road network condition in the Republic of Serbia, with the total length of 13 191,34 km
