The Effectiveness of IRI Compared to SDI System for Assessing the Quality and Performance of Materials Used in Flexible Pavement in Java, Indonesia

Abstract

Technological developments regarding the tools and methods used to determine the level of damage to roads, does not necessarily assure benefits to its users. Need further analysis and testing to determine its effectiveness. In terms of damage to the road using flexible pavement, IRI (International Roughness Index) method needs to be studied and compared with the SDI (Surface Distress Index) method which has been used in Indonesia. Damage to the roads using flexible pavement indicates the quality of materials used in flexible pavement. The method used in this study is a survey directly in the field using both methods. Then the results were compared and analyzed using statistical analysis. The purpose of this study was to determine the effectiveness of IRI compared to SDI. The result reveals that there are no significant differences between IRI and SDI. In other words, IRI can be used singly replace SDI.
