Performance

Construction Builds Communities

Since our foundation, Toa Road Corporation has been focusing on constructing road networks and transportation infrastructure including expressways and national roads in Japan.

Road Construction

Our operations includes road and expressway construction as well as paving on bridges and tunnels.
We also meet the recent demand of improving aged infrastructure.

Special Feature
  • Three Dimension Machine Controller (3D-MC) for Paver and Motor Grader
  • Slip Form Construction for Concrete Paver
  • Waterproofing for Bridge Slabs
  • Drainage Pavement
  • Porous Surface Mastic Asphalt Course (POSMAC)
    Simultaneous Laying Mixed Asphalt Material and Spreading Bitumen Emulsion
  • Multilevel Asphalt Pavement (MAP)
    Simultaneous Laying two Mixed Asphalt Materials such as Wearing and Binder Course
  • Cement and Asphalt Emulsion Stabilizer (CAE)
    Existing Pavement use effectively to Stabilized Base Course by Mixing Additional Cement, Bitumen Emulsion, Existing
    Pavement and Existing Base Course.
  • Construction Methods under Extreme Cold Condition (-27 Degrees)

Civil Works

Our Civil Works are mainly Airport Projects and Civil Construction Parts of the road projects.
We Design and Construct Pavement that support aviation safety during Take-off and Landing in Airport Project. We have two choices in Concrete Pavement Casting Method :
(1) Set-Form and (2) Slip-Form that depend on the cost, construction condition and requirements.
On the other hand, we have the Experience of civil works such as Earthworks, Structures, Drainage works, Protection works, Ancillary works and Miscellaneous in the road projects.


  • Airport Pavement

  • Tunnel Pavement
Superexpress "SHINKANSEN"

Cement Asphalt Mortar (CAM) can reduce the rail track vibration for SHINKANSEN when running. This rail systems adopts to projects that are being done around the world.

Railway Container Yards

Super Heavy Traffic Condition Project Wheel Load : 50ton
In purpose of smooth cargo handling operation with large forklift in container yard, durable pavement structure for heavy load is required.
We suggest construction plan for customer. We design pavement, drainage and structures including the comparison of cost performance.

Renewable Energy Project ( Photovoltaic Power Generation )

Global Environmental Project with growing interest to renewable energy, construction of mega solar facility is rapidly progressing. Our products and services are employed in developing mountain, forest and coastal areas.
We suggest construction plan designed Embankment, Cutting Soil, Drainage works and Solar Panels Foundation with considering the stability calculation in case of steel stakes or concrete foundation.

Making Roads Safer and Comfortable

We provide various pavement to prevent traffic accidents using 3dimension machine control to evenly flatten the road surface. Provide safe pavement drainage during rainy conditions and additional noise reduction during dry conditions. Solar radiation reflective and water retaining pavements are used to keep the roads on low temperatures during the times of "Island heat phenomenon or heat wave". We always make sure that our roads are Multi-function, High-Quality, Durable and Eco-friendly.
