Abstract

The project seeks to promote the National Economic Development (PEN), specifically targeting the enhancement and advancement of economic activities on Sumatra Island. One of the current projects is the construction of the Sicincin - Padang Toll Road Section (STA 0+000 - 36+600) of the Pekanbaru - Padang Toll Road. This segment of the highway is a component of the Trans Sumatra highway network on Sumatra Island. The bearing capacity and settlement design of the spun pile foundation at the pile slab STA 7+443 - STA 7+569 Sicincin - Padang Toll Road were recalculated based on soil investigation data derived from SPT (Standard Penetration Test) results, subsequently compared with the findings from the PDA Test (Pile Driving Analyzer) conducted in the field. Soft soil issues were identified at STA 7 + 443, leading to the formation of fissures and landslides. The issues arose from the interaction between a pile foundation plate and the capacity of a revolving pile foundation. The objective of the study is to determine the bearing capacity and settlement of the rotating pile foundation at STA 7 + 443 - STA 7 + 569 using Standard Penetration Test (SPT) results and to compare these findings with the field data obtained from the Pile Driving Analyzer (PDA) test. The analysis conducted involved the adjustment of the N-SPT value utilizing tables and graphs in compliance with SNI 1725-2016, SNI 8460-2017, and SNI 4153-2008. The settlement assessment reveals the most significant discrepancy in the Meyerhoff Method compared to the PDA Test, amounting to 5.32%. The pile's settlement is within the allowable limit of 60 mm; hence it is deemed safe.

Abstract

The existence of the Bawen-Salatiga toll road has caused an increase in the volume of vehicles on the Tingkir Road section, Salatiga City. In the first year of the opening of the toll gate, the maximum volume of vehicles per day was 23,937, while in the second year there were 26,203 vehicles passing through per day. This number continues to experience a significant increase over time. In order to reduce the potential for traffic congestion, PT Trans Marga Central Java plans to widen the road section. This study aims to determine the thickness of the pavement and the cost that will be used in the Jalan Tingkir widening project, Salatiga City. The pavement thickness calculation employs the 2017 road pavement design manual method (MDP) and utilizes Kenpave software for structural analysis. The second edition of the Central Java Province Construction Work Unit Price (HSP) for clan buildings is used as a reference for determining the cost of pavement work. Based on the results of the analysis, the thickness of the pavement layer was obtained: 40 cm for the AC-WC layer, 60 cm for the AC-BC layer, 80 cm for the AC base layer, and 30 cm for the class A foundation layer with a planned traffic load of 3.85 x 10⁶. ESAL. As for the strength value tested with Kenpave software, the repetition value of fatigue crack load (Nf) was 3.70 x 1012, the repetition value of groove crack load (Nd) was 4.41 x 106, and the repetition value of permanent deformation load was 3.19 x 1011. Based on the analysis of the cost budget plan, the cost for the pavement work was Rp9,019,773,857.81. The flexible pavement with a thickness of 48 cm can withstand the weight of fatigue cracking, groove cracking, and permanent deformation.

Abstract

The construction of the Serang–Panimbang Toll Road Section III Phase 2 Package 3 was part of a National Strategic Project requiring a strong foundation to overcome soil settlement. Spun piles were used as the primary foundation to resist both vertical and horizontal loads. This study aimed to determine axial bearing capacity based on pile driving (calendering) and SPT data analysis, calculate lateral bearing capacity, and evaluate pile settlement and displacement. Pile driving analysis showed varying capacities, with the lowest value from the Navy-McKay formula (371.782 kN) and the highest from the WIKA formula (926.061 kN). The Meyerhof α formula from SPT analysis produced the highest axial capacity (1052.162 kN). Lateral bearing capacity based on Broms (1965) exceeded allowable limits in both sand (9608.429 kN) and clay (6272.101 kN). Pile settlement occurred as a response to structural loads acting on the foundation and was influenced by the physical and mechanical properties of the supporting soil beneath. Based on elastic analysis using Vesic’s method (1967), the maximum settlement was (25.224 mm), occurring at the interaction zone between the spun pile and dominant soil layers at foundation depth. This value remained within the safe limit according to SNI 8460:2017. Overall, the spun pile foundation proved effective in maintaining stability under vertical and horizontal force while ensuring structural integrity and sustainability against potential settlement and displacement.
