Perencanaan Pekerjaan Ruas Jalan dan Jembatan Kalibagor (Link 35.060.13k) Di Dinas Pekerjaan Umum Bina Marga Provinsi Jawa Timur

Planning of Kalibagor Road and Bridge Works (Link 35.060.13k) at the Public Works and Highways Department of East Java Province

Abstract

Bridges are vital land transportation infrastructure because they function as inter-regional connections and determine the smooth flow of traffic. The Kalibagor Road and Bridge sections located on the Bondowoso Regency Boundary Road Section – Situbondo City Boundary have been damaged, so systematic re-planning is needed and in accordance with technical standards. This study aims to compile road and bridge pavement structure planning by referring to the Road Pavement Design Manual No. 02/M/BM/2017 and Flexible Pavement Thickness Planning Guidelines Pt T-01-2002-B. The planning method includes analysis of the road body structure, road shoulders, slope reinforcement abutments, road supplementary buildings, bridge superstructures and substructures, and drainage systems. The results of the study indicate that the type of pavement used is flexible pavement with specifications: 4 cm thick AC surface layer, 6 cm ATB top base layer, and 30 cm class A aggregate subbase layer. The road shoulder structure uses a 25 cm thick K-250 concrete top base and a 15 cm class A aggregate subbase. The new bridge is planned to use H-125 prestressed girders with a length of 16.60 m, a total width of 10.00 m, a traffic width of 7.00 m, and equipped with a 1.20 m sidewalk. The substructure uses reinforced concrete abutments with Ø 0.80 m bored pile foundations with a length of 17.00 m, and a retaining wall (DPT) of Ø 40 cm with a length of 10.00 m. The results of this planning produce a Detailed Engineering Design (DED) which is expected to be a reference in the construction of Kalibagor road and bridge infrastructure to improve community mobility and economy.
