"ER Ascon" is a polymer-modified asphalt mixture developed as a paving restoration material for manhole cover replacement and repair work. Compared to general asphalt mixtures, it is highly durable, with minimal flow or deformation due to the load of passing vehicles and increases in surface temperature, effectively eliminating the height difference between the iron cover and the pavement, thus preventing vibrations and noise from passing vehicles. Additionally, the softening point of the binder is above 80°C, and it has excellent aggregate scattering resistance, making it suitable for snowy and cold regions. 【Features】 ■ On-site mixing ■ Minimal settlement with little height difference ■ Capable of thin-layer pavement repairs ■ Excellent aggregate scattering resistance ■ Well-suited for snowy and cold regions *For more details, please refer to the PDF materials or feel free to contact us.

• Paving Materials

"S.F Mortar" is a super-fast-setting, high-flow, non-shrink mortar developed for height adjustment and filling gaps in construction work such as replacing manhole covers. It is premixed with various admixtures based on ultra-fast-setting cement to prevent cracks caused by the accumulation of heat generated during curing and to enhance durability. Additionally, it has a quick curing time, achieving the required strength in a short period. 【Features】 ■ Super-fast-setting type ■ Suppresses and reduces cracks due to heat accumulation ■ Quick curing time, achieving the required strength in a short period ■ Highly flowable and excellent filling material ■ Bleeding has non-shrink properties *For more details, please refer to the PDF document or feel free to contact us.

• Mortar and plaster materials

"Gata Closer" is a liquid-type pavement repair material that can also be used for filling potholes. When manholes on the road become loose due to passing vehicles, or when the pavement is cracking and about to pop up like a turtle's shell, injecting this material can stop the looseness and prevent scattering. Additionally, it has good fluidity, allowing it to flow into narrow spaces and prevent the expansion of cracks. 【Features】 ■ Cures in a short time ■ Enables early traffic reopening ■ Good fluidity ■ Flows into narrow spaces to prevent crack expansion ■ Can also be used for filling potholes *For more details, please refer to the PDF document or feel free to contact us.

• Reinforcement and repair materials

The "Safety Flat P.B Method" is a pavement auxiliary method that involves burying manhole covers beneath the pavement before the paving work. Since it allows for uniform compaction, it offers excellent durability and enables high-quality, flat pavement without any steps. As a result, maintenance and repairs are reduced, allowing for a decrease in running costs. 【Features】 ■ Achieves shortened construction time and cost reduction ■ Ensures the safety of road users ■ Enables durable pavement ■ Provides a comfortable road surface without noise or vibration *For more details, please refer to the PDF document or feel free to contact us.

• Pavement construction

The "Safety Flat Construction Method" is a circular manhole cover construction technique that allows for paving without noise or vibration from passing vehicles, due to the flatness of iron covers and similar materials. This method significantly improves work efficiency, shortens construction time, and achieves substantial cost reductions in machinery damage, transportation costs, and labor expenses. Additionally, it allows for uniform compaction, resulting in high-quality, flat pavement. 【Features】 ■ Environmental conservation along the road ■ Consideration for construction safety ■ Significant improvement in work efficiency ■ Substantial cost reduction ■ Quality assurance *For more details, please refer to the PDF document or feel free to contact us.

• Pavement construction

The "High-Grade Construction Method" is a new technique developed to prevent rainwater infiltration into the subgrade and to improve the durability of pavements and circular construction methods, utilizing the characteristics (stability) of ER asphalt concrete. By creating steps and establishing transverse joints, it prevents rainwater from entering the subgrade. By applying a rough surface treatment, adhesion increases, which suppresses the occurrence of ruts, flow, deformation, and peeling of the pavement material caused by passing vehicles, thus maintaining flatness and enabling vibration mitigation. 【Features】 ■ A new construction method developed utilizing the characteristics (stability) of ER asphalt concrete ■ Prevents rainwater from entering the subgrade by creating steps and establishing transverse joints ■ Prevents rainwater infiltration into the subgrade and helps prevent pavement frost heave ■ Distributes the load on the joints affected by passing vehicles, improving durability ■ Suppresses the occurrence of ruts, flow, deformation, and peeling of the pavement material caused by passing vehicles *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction Method

We would like to introduce the "P.B. covers for paving work" handled by C.S.K. With a safety factor three times that of the direct load, there is no strength reduction due to rust, and the concentric circle pattern makes it easy to identify the center of the manhole. We offer sizes including "φ820mm for sewer manholes," "φ1,000mm for electrical and communication use," and "φ1,100mm for water and sewer parent-child covers." 【Features】 ■ Available for rental ■ No strength reduction due to rust with a safety factor three times that of the direct load ■ The concentric circle pattern makes it easy to identify the center of the manhole ■ Material: Ductile cast iron (FCD-700) *For more details, please refer to the PDF document or feel free to contact us.
