Relationship between International Roughness Index and Straightedge Index

Journal of Transportation Engineering, 2012
AbstractThis study presents the regression relationships between two commonly used indicators of longitudinal road unevenness, the international roughness index (IRI) and the straightedge index. A total of 290 real longitudinal road-profile records were processed. The asphalt-concrete and cement-concrete road surfaces were analyzed separately.

Switching to International Roughness Index

Transportation Research Record: Journal of the Transportation Research Board, 1998
The International Roughness Index (IRI) has become a well-recognized standard for measurement of pavement roughness. The main objectives of the study were to evaluate the consequences of switching to IRI roughness measurements, and to develop a procedure for switching from measuring roughness with a response-type device, used for more than 10 years, to

Optimization of International Roughness Index Model Parameters for Sustainable Runway [PDF]

Sustainability, 2021
Pavement roughness is a critical airport pavement characteristic that has been linked to impacts such as safety and service life. A properly defined roughness evaluation method would reduce airport operational risk, prolong the life of aircraft landing gear, and optimize the decision-making process for pavement preservation, which together positively ...

Estimation of Present Serviceability Index from International Roughness Index

Transportation Research Record: Journal of the Transportation Research Board, 1999
An analysis is described that was undertaken with the objective of developing realistic models for estimating present serviceability index (PSI) as a function of international roughness index (IRI) for asphalt and concrete pavements. These models were developed by first analyzing the correlation between slope variance and PSI values obtained in the ...

IRI (International Roughness Index): An Indicator Of Vehicle Response

Materials Today: Proceedings, 2018
Abstract Public roads are the principle source of excitation to ground vehicles. Objective roughness/severity classification of the public roads is essential to predict vehicle response/fatigue damage at an early stage of vehicle development program.
