[Super Soil Construction Case Study] A1 Case of Embankment Lightweighting through Weak Ground Measures
Super Sol L2
This is an example of the improvement work for the Iwami IC No. 2 on the Route 9 Saji Mountain Bypass in Iwami District, Tottori Prefecture.
We would like to introduce a case study of the construction of the artificial lightweight material "Super Sol," made from crushed and sintered waste glass, in the context of "lightweight embankment measures for soft ground countermeasures." This project involved embankment work associated with the construction of a new road. As a countermeasure for soft ground, it was necessary to lighten the embankment for the protection of box culverts and to address differential settlement, leading to the use of the environmentally friendly material Super Sol. Width: Approximately 15-27m, Length: Approximately 47m, Embankment height: Approximately 6m, including behind the bridge abutment. 【Construction Case Study】 - Project Details: National Route 9, Shichiyama Bypass Iwami IC Second Improvement Work - Usage Category: Civil Engineering / Behind Bridge Abutment / Roadbed - Client: Ministry of Land, Infrastructure, Transport and Tourism, Chugoku Regional Development Bureau - Construction Location: Iwami County, Tottori Prefecture - Required Performance: Lightweight, Strength, Soil Pressure Reduction For more details, please contact us or download the catalog.

Company information
"Super Sol," made by crushing and sintering waste glass, is a lightweight material with countless holes, forming a porous structure. It is an artificial lightweight stone with an irregular shape and a particle size of 2 to 75 mm. There are products with varying specific gravities and water absorption rates to suit different applications. Composed of soil components, it is an eco-friendly product with an eco-mark. **Features of Super Sol:** - **Lightweight:** It is 1/6 to 1/5 the weight of soil, with a proven track record as a lightweight fill material. By combining it with crushed stone, the unit weight can be controlled between 4 kN/m³ and 11 kN/m³. - **Drainage:** It can be used as a drainage material in civil engineering and greening projects. - **Aeration and Water Retention:** It can be used as an inorganic soil amendment for greening. - **Workability:** Its lightweight nature makes it easy to handle, facilitating construction in uneven terrains and confined spaces. Like crushed stone, it can be installed through leveling and compaction without the need for curing periods or special techniques. - **Stability:** Being mineral-based and inorganic, it is physically and chemically stable, with no corrosion. - **Safety:** As it is made from naturally derived glass, Super Sol is composed of soil components, making it a highly safe material for the surrounding environment.
