Abstract
Lemahnendeut is a road located in Bandung City. The condition of the road surface on this road has experienced significant damage. Additionally, Lemahnendeut road features a curve combined with a descent, specifically in front of Sari Ater Kamboti Hotel. Therefore, this study will analyze the geometric conditions according to the Geometric Design Guidelines for Roads Number 20/Se/Db/2021 and will evaluate the road surface, followed by an analysis of the impact of geometric conditions on the road surface. Based on calculations according to PDGJ 21, the curve on Lemahnendeut road should be of the Spiral Circle Spiral (SCS) type. However, based on the existing condition analysis, all curves on this road are of the SCS type. There is 1 curve with the FC type and 2 curves with the SCS type, and there are components of the curves that do not meet the minimum criteria required. The assessment of the road surface based on the Pavement Condition Index (PCI) method concludes that the road is in good and very good condition, while the International Roughness Index (IRI) method concludes that the road is in lightly damaged and severely damaged condition. Statistical analysis in the form of correlation and regression tests of geometric variables (slope, R, superelevation) against the surface conditions (PCI and IRI) shows no relationship or effect of geometry on PCI, but there is a very weak correlation and effect of geometry on IRI.
