The IKN area, especially in the dock and stockyard construction area, is in an area with soft surface soil and requires several options for handling the stockyard area with several materials that are being widely used and easy methods and provide economic value in development. The use of geoform can increase the CBR value of native soil and the use of geofoam as embankment material provides a higher safety factor value with a smaller deformation value besides that the foam mortar material contributes to a small decrease and stress on the surface of the native soil. This study provides a behavioral review of the vertical settlement and stresses that occur in the soil and gives special behavior to the Geofoam material in the presence of hydrostatic forces. The largest settlement that occurred was 0.0961 m on the surface of the foam mortar, while on the existing soil surface a settlement of 0.0288 m occurred, while the largest settlement that occurred was 0.04254 m on the surface of the geofoam, while on the existing soil surface a settlement of 0.0277 m occurred.

“…The soft subgrade caused a problem in the construction of the road. The problems that often occur in embankments on soft soils are embankment stability problems and a big consolidation settlement problem in a relatively long time [2]. Indonesia has an area with soft soil of about 20 million hectares (the percentage of Indonesia's land area is about 10%) [3].…”

The major issues of building a road over soft soils are low bearing capacity and large settlements. The challenges of road construction on soft soils are enormous, so innovative and environmentally friendly methods are required. Geofoam is a type of lightweight infill material and was already used in Norway in road construction applications in 1972. Using Geofoam reduces compacted fill by 40%, less excavation required and less pulverization of native soil making this a time-saving and economically and environmentally viable solution. The purpose of Geofoam backfill is for lightweight backfilling, reducing soil pressure. Geofoam blocks can be used as a substitute for soft soil fill or as fill on top of soft soil as subgrade for pavement. This paper discusses the latest developments on the various applications of Geofoam blocks as backfill in soft soils presented based on information provided by the author.

“…Although the basic cost of EPS Geofoam is high, taking into account other factors such as transportation costs, there is no The cost of compaction required, machinery, and material availability, make EPS Geofoam feasible and economical for long term considerations. Research results (Hidayat & Suhendra, 2011) based on calculation results using the Plaxis 2D program show that the use of geofoam as filling material for embankments provides several advantages compared to embankments using laterite soil, namely: Higher safety factor Geofoam, SF = 1,77 Laterite soil , SF = 1,10. The results of research (Atamini & Moestofa, 2018) show that the gradual comparison of the settlement that occurs between red laterite red soil piles and foam mortar light embankments, the use of foam mortar light embankments on soft soil will result in smaller settlements (<74.40% ) compared to the laterite red soil option, because the foam mortar embankment can reduce the amount of settlement that occurs due to the light weight of the material.…”

The Pasuruan-Probolinggo Section 4 Toll Road project which has a length of 12.04 km is dominated by silty clay -clay. In addition to soft soil, there are other problems in the construction of the Pasuruan -Probolinggo Section 4 toll road, namely the limited availability of embankment soil material around the project site and the location of the quarry which is quite far away. In addition, when relying on embankment material from the quarry, the weather factor will play a very important role when the weather is rainy then the activity in the quarry stops, the targeted embankment volume is not met and the progress of work on that day is not achieved. Therefore, there is a need for alternative reinforcement of embankments other than soil embankments from quarries that are safe and light enough. Based on the existing problems, this research will conduct a comparative study of toll road embankment design with 3 different types of materials, namely: Conventional soil embankment compared with lightweight embankment in the form of EPS-Geofoam material and foam mortar material. This research will use Plaxis 2D program. The results of this research will determine alternative embankment materials that can be applied to soft subgrade so that overall stability and hydrostatic uplift requirements can be met. This research is expected to be a reference in planning the construction and improvement of the subgrade of the Pasuruan-Probolinggo Section 4 toll road and other toll roads using EPS geofoam embankment and foam mortar
