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

open access: yesRekayasa 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]

open access: yes, 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 ...

Analysis of surface roughness in relation to soil loss and runoff at high rainfall intensities. [PDF]

open access: yes, 2002
The decay of roughness is an important factor governing surface processes such as infiltration and soil erosion. Thus the decay of surface roughness under different surface conditions was investigated and related to quantitative amounts of soil loss ...

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

open access: yesAdvances 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.

International Roughness Index (IRI) prediction models for freeways

open access: yesTransportation Research Procedia, 2023
In Pavement Management Systems (PMS), pavement performance models, or pavement deterioration (or evolution) models are regarded as a key element because they are able to forecast the future condition of the pavement based on available data. Hence, once pavement performance is predicted for next years, the optimal moment and treatment can be planned to ...

Dynamic evolution of interface roughness during friction and wear processes [PDF]

open access: yes, 2014
Dynamic evolution of surface roughness and influence of initial roughness (Sa=0.282 to 6.73 µm) during friction and wear processes has been analyzed experimentally.

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

open access: yesTransportation 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 ...

Hot-in-place recycling engineering application of low penetration aged asphalt [PDF]

open access: yesE3S Web of Conferences, 2023
Hot-in-place recycling of asphalt pavement is one of the important regeneration technologies of pavement engineering, which apply to the pavements with fewer diseases, excellent driving quality, slight rutting, and good pavement structural strength ...
