We possess the technologies needed for efficient construction of expressways that are safe, comfortable, and highly resistant to natural disasters.
We construct bridges between steep mountain slopes, urban overpasses, and a variety of other site conditions in a cost-effective way.
To overcome factors such as faults and fracture zones, proper construction management is conducted using NATM,Shield methods and TBMs.
We perform earthwork management such as slope stabilization and road embankment quality control even in areas with soft ground or areas susceptible to landslides.
Introducing porous asphalt surfece on our expressways increases skid resistance and improves safety during high speed driving in rain.
