EVALUASI KONDISI PERKERASAN LENTUR PADA RUAS JALAN IMOGIRI TIMUR KM 7 − KM 9 DENGAN METODE PCR (EVALUATION OF FLEXIBLE PAVEMENT CONDITION ON THE EAST IMOGIRI ROAD SECTION KM 7− KM 9 USING PCR METHOD)

Abstract

East Imogiri road section km 7 to km 9 is a collector road located in Bantul district. Pavement at this location many have suffered damage such as cracking and patching / Potholes. Pavement must have a good service performance and in terms of the functional condition of the road can not support the traffic load through it. This study aims to identify the type of road damage and the level of damage to roads. The study was conducted by collecting primary data in the form of value Surface Condition Rating (SCR) by measuring the extent of their damage by using a ruler and the value of the flatness of the road or the International Roughneess Index (IRI) are obtained by using roughometer. Secondary data obtained from previous research. Furthermore, the data that has been collected and analyzed by the method of Pavement Condition Rating (PCR) and the determination of the type of road maintenance based on the method of Highways in 1990. Based on the evaluation of pavement condition Imogiri Eastern km 7 to km 9, the value of PCR Based on the evaluation of pavement condition Imogiri Eastern km 7 to km 9, the value of PCR and determination of the type of road maintenance based on the method of Bina Marga. PCR value-smallest in the direction of Yogyakarta-Imogiri is 46.77 in the category of ugly, and for direction Imogiri-Yogyakarta is 36.44 in the ugly category. Based on the analysis of Bina Marga, direction Yogyakarta-Imogiri there are 13 segments require regular maintenance program and 7 segments require periodic maintenance program. While the direction of Imogiri-Yogyakarta there are 12 segments require regular maintenance program and 8 segments require periodic maintenance program
