국도 아스팔트 포장의 NHPCI(National Highway Pavement Condition Index)를 활용한 보수공법그룹 결정에 관한 연구 = A Study for Determining the Rehabilitation Method Group using NHPCI on Asphalt Concrete Pavement of National Highway

다국어 초록 (Multilingual Abstract)

PURPOSES : The PMS(Pavement Management System) has been utilized in order to efficiently allocate the limited budget for the maintenance of national highway system. In the PMS of national highway, surface pavement condition is evaluated by using the VI (Visual Index). However, the VI is determined only by considering the cracking rate (%) and rut depth (mm), which is not reflecting the IRI (International Roughness Index) that is known as an important factor of pavement performance. In this study, the NHPCI (National Highway Pavement Condition Index) which includes the cracking rate (%), rut depth (mm), and IRI (m/km) is suggested for determining the rehabilitation methods group.
METHODS: First, the rehabilitation methods performed between 2008 and 2010 on the national highway is classified and then, NHPCI is determined for each rehabilitation method. Next, the NHPCI for each rehabilitation method is grouped through the interval estimation of the population mean and T-test analysis.
RESULTS: According to NHPCI range, the rehabilitation methods are divided into four categories: Not Required, Preventive Maintenance,Overlay Treatment (with or without cutting), and Full-scale Treatment (i.e., reconstruction).
CONCLUSIONS : Based on this study, it is recommended that the appropriate NHPCI range should be determined through the combination of the rehabilitation categories and Decision Procedure of Pavement Distress Condition Visual Index.
