Evaluation of Pavement Condition Based on Pci and Rci Value on Km 11 - Km 12,5 Magelang Road, Magelang District

Abstract

The research heads for knowing the quality of pavement on km 11 – km 12,5 Magelang Road, Magelang District at present based on Pavement Condition Index (PCI) and Road Condition Index (RCI) value, and then done by the handling programme according to PU : 13/PRT/M/2011. Measuring procedure at field for PCI value is using gauge to find out the width of detriment and grouping detriment level, then it’s being analyzed by FAA standard (1987). The IRI value is obtained by testing roughometer. The RCI value is obtained based on correlation result by IRI value that being analyzed by 3 equation methods such as Sukirman (1999), Paterson (1986), and Al Omari (1994). Based on the estimation of International Roughness Index (IRI) and then it’s done by the analysis to determine the condition, expediency, ant the needed kind of roadwork according to PU : 13/PRT/M/2011. Result shows that PCI value on Magelang Road is fail-bad at 3,5%, medium at 26,5%, and good-very good at 70% and dominated by kind of detriment like patching with the average of density 10,38% and 6,05% on the contrary. The IRI value on direction of Yogyakarta-Magelang is dominated by good condition with percentage of 63,33% rating 4, meanwhile on direction of Magelang-Yogyakarta is dominated by good condition with percentage of 96,67% rating 4. The RCI value with Al Omari equation model (1994) on the direction of Yogyakarta-Magelang is dominated by medium condition with percentage of 40%, while on direction of MagelangYogyakarta is dominated by medium condition with percentage of 93,33%. Programme of road condition for two directions by analysis of PU : 13/PRT/M/2011 is need to do maintenance regularly/periodic.
