Correlation Analysis between Pavement Condition Indices in Korean Roads

다국어 초록 (Multilingual Abstract)

The Korean road network has been aging rapidly. It is necessary to assess the pavement conditions of various road networks inorder to come up with proper rehabilitation strategies against the aging road networks. Pavement management system is an essentialtool for road management, and each road management organization has developed its own pavement condition index for assessingthe road conditions. Nonetheless, because the pavement condition of various types of roads could not be represented by a singlepavement condition index, it was difficult to comprehend the condition of the entire roads of Korea and its changing trend at a glance.
Moreover, there has been a limitation on the persuasion of the justification for the use of road management and rehabilitation budgetat national level to the people and the budget office of Korea. This study derived the relationship among the pavement conditionindices of Korean expressways, Korean national highways, and Seoul city roads so that those pavement indices can be represented byone unified pavement condition index. A sensitivity analysis of how variables of pavement distress (roughness, rut depth, and crackratio) influenced each of the pavement condition index was carried out. Then, correlation equations between the pavement conditionindices were developed in order to represent them by a single pavement condition index (NHPCI) through a statistical analysis of thepavement condition monitoring system data over 8 years, and its application plan is proposed.
