Development of Methods and Specifications for the Use of Inertial Profilers and the International Roughness Index for Newly Constructed Pavement
The Indiana Department of Transportation (INDOT) is currently utilizing a profilograph and the profile index for measuring smoothness assurance for newly constructed pavements. However, there are benefits to implementing a new International Roughness Index (IRI)–based smoothness specification utilizing road profiles measured using inertial profilers. Technological advancements have improved the...
متن کاملInternational Public Sector Accounting Standards, Good Governance and Crime Index: An International Evidence
The purpose of this study is to investigate the effect of International Public Sector Accounting Standards (IPSAS) on good governance and, therefore, crime index. To investigate this issue, data related to the status of the public sector accounting system, good governance indicators as well as crime index of 30 countries in the period 2015 to 2019 are collected and analyzed. This paper shows th...
متن کاملConsidering a New Sample Unit Definition for Pavement Condition Index
One of the main components of pavement management system (PMS) is pavement evaluation. Several indices have been defined for the evaluation of existing pavement. The Pavement Condition Index (PCI) is a common index used for pavement evaluation. In order to calculate PCI, a significant volume of condition data -based on distress surveying- is required. The objective of this research is to reduce...
متن کاملFunctional Unit Choice for Comparative Pavement LCA Involving Use-Stage with Pavement Roughness Uncertainty Quantification (UQ)
An analysis of the use-stage for pavement life-cycle assessment (LCA) is presented within a framework of an LCA tool developed for Illinois Tollway. Methodological choices that can significantly affect LCA results were evaluated in this study. The share of the use-stage in a comprehensive pavement LCA framework was evaluated with all life-cycle stages including materials, construction, use, mai...
متن کاملIdentification and Prioritization of Accident-Prone Segments using International Roughness Index
During last decades, owing to the increase in a number of vehicles, the rate of accident occurrence grows significantly. Efforts must be made to provide efficient tools to prioritize segments requiring safety improvement and identify influential factors on accidents. This objective of the research was to determine the safety oriented threshold of International Roughness Index (IRI) to recognize...
