Relationship between the Pavement Condition Index (PCI), Present Serviceability Index (PSI), and Surface Distress Index on Soekarno Hatta Road, Bandung

Abstract

Evaluation of the conditions of Jalan Soekarno Hatta using the PCI method shows that the most found is the condition of "Good" both on rigid and flexible pavement, with the percentage of each of them being 61.9% and 21.6%. Whereas by using the PSI method, the most commonly found are "Fair" conditions both in rigid and flexible pavement, with the percentage of each being 81% and 48,9%. Using the SDI method on the flexible pavement the most found is the condition of "Medium" with a percentage of 65,9%. The parametric analysis between PCI and PSI on rigid pavement produces R2 = 0.0548 with a regression equation namely PCI = 96,66 – 3,9352 x PSI, while the PCI and PSI correlation on flexible pavement produces R2 = 0.8163 with regression equation namely PCI = 27,673 + 16,848 x PSI., and the PCI and SDI correlations on flexible pavement yields R2 = 0,8653 with a regression equation namely PCI = 94,663 – 0,4462 x SDI The non-parametric analysis between PCI and PSI on rigid pavement produces a correlation coefficient of 0.043, while the PCI and PSI values on flexible pavements produce a correlation coefficient of 0.397, and the PCI and SDI values on flexible pavements produce a correlation coefficient of 0.492. Based on the two analysis methods both parametric and non parametric analysis the relationship between PCI and SDI was considered better than the PCI and PSI relationship because it produced a R2 value and had greater correlation coefficient.
