ANALYSIS OF PAVEMENT THICKNESS OF ROAD REHABILITATION PROJECT SP. LIANG ANGGANG –CITY BOUNDARY OF PELAIHARI SECTION 1 (STA. 3+700 - STA. 7+300) CITY OF BANJARBARU

Abstract

Roads are an important role for life, as road infrastructure there are still many problems such as less safe, comfortable and some are located in flood-prone areas. the case is like in the SP segment. Liang Anggang - Ds. Liang Anggang (Bts. Tanah Laut Regency) is a location affected by flooding, so it is necessary to raise the road body to the specified flood water level, so to overcome this problem it is necessary to raise the road body so that road infrastructure can support both the safety and comfort of road users. The purpose of this study was to re-plan the flexible pavement thickness using the Road Pavement Design Manual Method Number 02/M/BM/2017 and the Pt-T-01-2002B method, as well as to compare the calculation results and pavement thickness with the Planning Design.

The results of the planning using the Flexible Pavement Design Manual method Number 02/M/BM/2017, namely with a surface layer of AC–WC 40 mm, AC–BC 60 mm, AC–BASE 105 mm, Upper Foundation Layer with Class A Aggregate 300 mm and Support layer with optional fill of 550 mm, and Road Shoulders with Class S Aggregate Foundation layer of 205 mm. The Pt T 01-2002-B method requires a surface layer of 40 mm AC–WC, 70 mm AC–BC, Upper Foundation Layer with Class A Aggregate 210 mm, and Lower Foundation Layer with Class B Aggregate 230 mm. From the planning results of the two methods to be compared with the Plan Drawings, there are differences in the surface layer requirements where the Flexible Pavement Design Manual Method Number 02/M/BM/2017 with the Plan Drawings both use AC–WC, AC–BC, and AC-BASE. while the Pt T 01-2002-B method does not use AC-BASE. There is no difference in Upper Foundation Layer or both use Class A Aggregate Foundation, while significant differences occur in the sub-base layer as subgrade improvement, there is a difference, namely in the Flexible Pavement Design Manual method Number 02/M/BM/2017 and Plan Drawings using support layer using selected fill while the Pt T 01-2002-B method uses Class B Aggregate Lower Foundation Layer. The magnitude of the difference in pavement thickness occurs due to differences in pavement design and material selection, the Flexible Pavement Design Manual method Number 02/M/BM/2017 for the type of material has been determined in the table while the Pt T 01-2002-B method can plan the type of pavement material you want to planned.
