Study of Pavement Performance Indicators: RII Approach


Objectives: In the present study, evaluation of Relative Importance Index (RII) of sixteen pavement performance indicators has been carried out. Methods/Statistical Analysis: For the study total sixteen indicators are considered which includes structural and functional indicators. Relative Importance Index is calculated by obtaining opinion of academician and professional experts from the field of transportation engineering. Questionnaire Survey methodology has been adopted for collection of experts opinion. Five linguistic terms are used for the same, which are, ‘Very important’, ‘Important’, ‘Average’, ‘Less important’ and ‘Not important’. Findings: It has been observed from the values of RII, that, in case of flexible pavement deflection and potholes get maximum index followed by longitudinal cracking and Rutting. In case of rigid pavement Longitudinal cracking get maximum value followed by Transverse cracking. Application/Improvements: The values obtained from the study can be used for pavement condition evaluation incorporation with experimental evaluation of pavement surface condition for rating of pavements.
