Preventing rainwater from entering the roadbed! A circular manhole cover replacement method that can prevent pavement heave.
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.
