Sensitivity of International Roughness Index to Distresses of Cement Concrete Road Surfaces

open access: yesCommunications, 2016
The paper examined the sensitivity of International Roughness Index (IRI) to the local discontinuities (various distresses, joints, joint and surface defects, other road features, etc.) of the cement concrete (CC) pavements.

Dual Model for International Roughness Index Classification and Prediction

open access: yesInfrastructures
Existing models for predicting the international roughness index (IRI) of a road surface often lack adaptability, struggling to accurately reflect variations in climate, traffic, and pavement distresses—factors critical for effective and sustainable ...

Smooth Enough?: Estimated Roughness on Roads with Low International Roughness Index Values

open access: yesTransportation Research Record: Journal of the Transportation Research Board, 2003
The reported investigation is one part of a project concerning methods for measurement of the longitudinal roughness of roads and the necessary accuracy. In this study the main focus was on the subjective experience of roughness on roads with low international roughness index (IRI) values, that is, fairly good roads. With the available data it was also

Precise International Roughness Index Calculation

open access: yesInternational Journal of Pavement Research and Technology, 2021
Roadway infrastructure management focuses on quality of the road surfaces which influences the pavement longevity and riding quality. The road surface quality can be expressed in many ways from which the International Roughness Index has been recognized widely around the developed countries.

Can We Predict the Roughness Index (IRI) of a Road Based on its Pavement Condition Index (PCI)? [PDF]

open access: yesE3S Web of Conferences, 2023
Road damages might affect pavement condition which leads to reducing the remaining service life of the pavement. Two methods widely known to measure the pavement condition are among others: the Pavement Condition Index (PCI) and the International ...
