Geometric Evaluation and Analysis of Road Pavement on the Buper - Kemp Road Section, Wolker Waena

Abstract

The topography in Jayapura regency is generally an area consisting of mountains and valleys that have various elevations, and the transportation facilities are also diverse. Geometric evaluation on the Camp road section. Wolker – Buper Waena conducted a topographic survey of existing roads. To obtain geometric data, then geometric evaluation is carried out based on RSNI T-14-2004 (Guidelines for Geometric Planning of Urban Roads) and Inter-City Geometric Planning Procedures, Department of PU, Directorate General of Highways, 1997. Road pavement analysis based on the Road Pavement Design Manual of the Ministry of PU No. 04/SE/DB/2017 and the Regulation of the Minister of PU No. 04/SE/M/2010.The conclusion of the study on geometric evaluation of horizontal alinyemen roads on the bends PI – 10 and PI – 11 did not meet the standard provisions. Similarly, vertical alinyemen exceeds the maximum limit of road slump, which is 10%. The slump is at sta 0+450 – 0+650 and sta 0+800 – 1+400. Thus, it needs re-planning. Analysis of road pavement at the  Cbr point of the field > 6%, the basic soil strength class SG6. Basic soil improvement foundation structure stabilization segment or preferred heap material (compaction of ≤ layer 200 mm loose thickness), no need for improvement. Then for the field Cbr < 2.5%, the basic soil strength class SG1 with a support layer of 700 mm. For a field Cbr of 2.5%, the base soil strength class is SG2.5 with a minimum soil improvement thickness of 175 mm. For field Cbr, 3 % uses basic soil strength class SG3 with a minimum thickness of soil improvement of 150 mm. For a field Cbr of 4%, a base soil strength grade of SG4 with a minimum soil improvement thickness of 100 mm. The pavement layer design obtained AC WC = 40 mm, AC BC = 60 mm and LPA Class A adjusts the minimum thickness of soil improvement of each segment.
