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

E3S 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 ...

The Identification of Road Condition Using Smartphone Roadroid Application Based on Correlation Method (Case Study: Bypass Lombok International Airport)

Rekayasa Sipil, 2022
A road is a land transportation infrastructure that plays an important role in regional development. Road feasibility assesses through road roughness. The purpose of this study is to assess the condition of road roughness based on the ASTM E 950-94.

Bridge roughness index as an indicator of bridge dynamic amplification [PDF]

, 2006
The concept of a road roughness index for bridge dynamics is developed. The International Roughness Index (IRI) is shown to be very poorly correlated with bridge dynamic amplification as it takes no account of the location of individual road surface ...

Development of a Relationship between Pavement Condition Index and International Roughness Index in Rural Road Network

Advances in Civil Engineering, 2021
The main objective of this paper was to investigate the relationship between PCI and IRI values of the rural road network. To this end, 6000 pavement sections of the rural road network in Iran were selected.

Evaluation of Longitudinal Irregularity in Airport Pavements and Unpaved Runway

Engineering Proceedings, 2023
This paper presents a study about the effect of unevenness on conventional airport pavements and unpaved runways. During landing and take-off operations, aircraft tires are at high levels of tension and possible surface roughness can contribute to ...

International Standards Organization-Compatible Index for Pavement Roughness [PDF]

Transportation Research Record: Journal of the Transportation Research Board, 1998
The development of a new pavement roughness index, which is compatible to the current International Standards Organization (ISO) standard on “exposure to whole-body vibration” is described. The index was intended to be the independent variable in the future development of relationships between user cost (i.e., vehicle depreciation, repairs, discomfort ...
