Geometric Evaluation of Roads on the Gunung Batu Road Section of Tapin Regency (STA 0 +000 – 1+451)

Abstract

Gunung Batu road section is a section of road located in Binuang District, Tapin Regency which is included in the classification of local roads with hilly terrain conditions. The speed of the road geometric plan is 40 km / h. The purpose of this study is to evaluate the existing horizontal arrangement plan whether it meets the 1997 Bina Marga standards and provide an alternative design for horizontal and vertical alinyemen assisted by Autocad Civil 3D 2018 software.

The method used is to follow the reference standards from AASHTO 2011, but for the study criteria using the 1997 Bina Marga standard. The data collection methods carried out in the preparation of this Final Project Report are Literature Studies, Primary Data and Sequence Data.

Based on the results of the analysis, it showed that the Horizontal Alinyemen at the location under review had 26 bends with the Full Circle type, there were 18 bends that did not meet the geometric planning requirements where the bends did not meet the R min value (minimum radius) requirements for the use of the Full Circle bend type according to the planned speed. The alternative design given produces a trase of 1+445.59 km, a Horizontal Alinyemen of 22 bends (FC), a Vertical Alinyemen of 21 Convex arches and 21 Concave Arches. Analysis of the calculation results of the Cut and Fill design was obtained: Cut = 8458.13 m³ and Fill = 3286.62 m³.
