Permeable soil-based slag paving material "Eternal Sand"

Permeable soil-based slag paving material "Eternal Sand"

Earth-based slag pavement that solves the weaknesses of earth-based pavement.

By using blast furnace crushed slag as the main aggregate, we have eliminated the peeling and flaking that were seen in the initial stages of conventional earth pavements. The durability is also excellent due to the slag's "latent hydraulicity" (a characteristic where strength increases over time due to hydration reactions). It has a natural color and texture similar to soil, without the artificial impression often seen in asphalt or resin-based materials. It also excels in functions such as permeability, water retention, and slip resistance. 【Features】 ■ Main composition of blast furnace crushed slag mixed with sandy soil ■ Resistant to water overflow on the surface, accommodating heavy rainfall of 30mm/h ■ Mitigates the heat island effect through evaporation from the surface ■ Provides moisture to trees and flowers through evaporation, promoting growth ■ Universal design that is easy for anyone to walk on ■ Extended lifespan compared to conventional paving materials ■ Reduces the extraction of natural materials by using artificial aggregates (recycled materials) *For more details, please refer to the PDF document or feel free to contact us.

Reasons why colored sand is strong against "freeze-thaw" cycles.

Reasons why colored sand is strong against "freeze-thaw" cycles.

Introducing technical information about permeable blast furnace slag pavement "Color Sand"!

This document explains the reasons why "permeable and water-retaining pavement materials (color sand)" are strong against "freeze-thaw" cycles. Color sand is a pedestrian pavement material that possesses permeable and water-retaining functions while being sufficiently resistant to the repeated effects of freeze-thaw cycles during winter, making it "strong against frost damage." Among our pavement composition, the "filter layer" made from high furnace slag pavement, when used alone, has a significant effect in suppressing "frost heave phenomena." Furthermore, in freeze-thaw tests conducted at the Central Testing Laboratory of the Building Materials Testing Center, no cracking or destruction occurred even after completing 200 cycles. 【Excellent Features of the Aggregate (High Furnace Slag)】 ■ Porous Structure - Numerous fine voids release pressure caused by volume expansion during freezing. ■ Potential Hydraulic Properties - The main components of water-cooled slag (silica, alumina, lime, magnesia) solidify over time due to repeated water penetration. ◎ Sufficiently resistant to the repeated effects of freeze-thaw cycles. *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

The technical basis of "permeable blast furnace slag pavement" that balances permeability and water retention.

The technical basis of "permeable blast furnace slag pavement" that balances permeability and water retention.

Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!

We will explain the technical basis of the "Permeable and Water-retaining Blast Furnace Slag Pavement (Color Sand)" that achieves both permeability and water retention. All of our paving materials use "water-quenched blast furnace slag" as the main aggregate. The aggregate itself has a fine porous structure, allowing it to provide both permeability and water retention. While typical permeable paving materials allow water to pass through at "points," our paving materials enable permeability across "surfaces" due to the nature of the aggregate itself, resulting in less clogging and maintaining permeability performance over a long period. Additionally, by cleaning with high-pressure washers, the permeability can be restored to about 80%. Further explanations regarding "permeability performance" and "water retention performance" can be found through external links. 【Introduction to Technical Information】 ■ Reasons for achieving both permeability and water retention ■ Permeability performance ■ Water retention performance ■ Our product lineup *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

[WIB Construction Method Case Study] Road Traffic Vibration Countermeasures for Residential Areas Along National Highways

[WIB Construction Method Case Study] Road Traffic Vibration Countermeasures for Residential Areas Along National Highways

Vibration measurements were conducted before and after the measures were implemented! A reduction of 4 to 5 dB in the vertical direction was confirmed!

In Saitama City, Saitama Prefecture, traffic vibrations from the national highway were affecting the living environment along the route, leading to complaints from residents. As a countermeasure, tire shred with high damping material was filled in the grid. Renovation work was carried out on the side road that runs between the national highway and residential areas, and the 'WIB method' was implemented directly beneath the road. Vibration measurements were conducted before and after the countermeasures, confirming a reduction of 4-5 dB in the vertical direction near the boundary between public and private properties. 【Case Overview】 ■ Construction Location: Saitama Prefecture ■ Client: Saitama City ■ Vibration Source: Road traffic vibrations ■ Preservation Target: Several residential buildings along the national highway ■ Countermeasure Work: Wall-type WIB method (grid type) ■ Construction Position: Vibration propagation path *For more details, please refer to the PDF document or feel free to contact us.

[WIB Construction Method Case Study] Vibration Control Measures for the Construction of New Expressways (2)

[WIB Construction Method Case Study] Vibration Control Measures for the Construction of New Expressways (2)

Compared to areas without measures, the ground vibration in areas with measures is about 6dB to 7dB lower! Vibration reduced to less than 1/2!

In Mie Prefecture, there were concerns that the construction vibrations from the new highway would propagate to nearby public facilities. As a countermeasure, the 'WIB method' was implemented directly beneath the construction vehicle road. After the measures were taken, running tests and impact tests using a backhoe were conducted, comparing the vibrations at the unprotected and protected locations. As a result, it was confirmed that the ground vibrations at the protected locations were approximately 6dB to 7dB lower than those at the unprotected locations, reducing the vibrations to less than half. 【Case Summary】 ■ Location: Mie Prefecture ■ Client: Tenox Co., Ltd. ■ Vibration Source: Construction work vibrations ■ Preservation Target: Nearby public facilities ■ Countermeasure: Plate-type WIB method (honeycomb cell type) ■ Installation Position: Directly beneath the vibration source *For more details, please refer to the PDF document or feel free to contact us.

[WIB Construction Method Case Study] Traffic Vibration Mitigation for Existing Roads

[WIB Construction Method Case Study] Traffic Vibration Mitigation for Existing Roads

Conducted driving tests with a 10-ton truck before and after the measures! We were able to achieve vibration reduction effects!

In Shizuoka Prefecture, vibration countermeasures were required in areas where complaints about vibrations had been occurring during road renovation work. As a result, the 'WIB method' was implemented directly beneath the road. Before and after the countermeasures, driving tests were conducted using a 10-ton truck. Vibration responses were measured and compared at the boundary between public and private properties along the road, on the ground within the site, and on the second floor of buildings. It was found that vibrations around the dominant frequency of 6Hz were reduced, achieving an average reduction of 10dB in the horizontal direction and 20dB in the vertical direction. [Case Summary] ■ Location: Shizuoka Prefecture ■ Client: Imamura Group Co., Ltd. ■ Vibration Source: Road traffic vibrations ■ Preservation Target: Several houses along the road ■ Countermeasure Method: Plate-type WIB method (honeycomb cell type) ■ Construction Position: Directly beneath the vibration source *For more details, please refer to the PDF document or feel free to contact us.

[WIB Construction Method Case Study] Pre-construction Vibration Simulation for Pile Driving Work

[WIB Construction Method Case Study] Pre-construction Vibration Simulation for Pile Driving Work

The impact of vibrations on residential areas and commercial facilities was found to be almost nonexistent, except for a very small range!

During the construction of a temporary platform for the sluice gate work, a vibro hammer was used to install the pile bridge pier. The impact of vibrations on surrounding residential and commercial facilities was evaluated through simulation analysis using the two-dimensional finite element method (2DFEM). Based on these results, the client conducted explanations of the vibration impact to nearby residents and surrounding commercial facility owners before the construction began. Some vibration effects were observed in residential areas close to the vibration source at the start of the pile driving, but the overall impact on residential and commercial facilities was minimal, with only a very limited area affected. 【Case Overview】 ■ Client: A certain construction consultant ■ Analysis Period: January 2020 ■ Cost: 1.77 million yen (excluding consumption tax, analysis fee for five measurement lines) ■ Vibration Source: Pile driving vibrations from a vibro hammer ■ Analysis Content: Evaluation of vibration impact on residential areas around the sluice gate *For more details, please refer to the PDF document or feel free to contact us.

[WIB Construction Method Case Study] Road Traffic Vibration Countermeasures for Model Houses (2)

[WIB Construction Method Case Study] Road Traffic Vibration Countermeasures for Model Houses (2)

Traffic vibrations transmitted from the ground have been reduced! An environment has been created that falls below regulatory standards after the measures were implemented!

At the model house along the main road in Chiba Prefecture, there were concerns about the impact of traffic vibrations on the living environment due to the proximity of a busy main road after the model house was newly constructed. The 'WIB method' was implemented directly beneath the model house, achieving a vibration reduction level of 12dB (about 1/4 of the original vibration). This model house is planned along a busy main road due to its appealing characteristics, but thanks to this construction, the traffic vibrations transmitted from the ground have been reduced, creating an expected quiet indoor environment suitable for the model house. 【Case Overview】 ■ Construction Location: Chiba Prefecture ■ Client: Tokyo Sekisui Heim Co., Ltd. ■ Vibration Source: Road traffic vibrations ■ Preservation Target: Model house along the main road ■ Countermeasure Method: Plate-type WIB (honeycomb cell type) ■ Construction Position: Directly beneath the receiving side *For more details, please refer to the PDF materials or feel free to contact us.
