Jointed plain concrete pavement

Roller compacted concrete pavement using eco-cement
The concrete is transported using a few dump trucks and leveling is performed using an asphalt finisher/paver. Compacting was performed using a vibrating roller and tire roller.
This construction seeks to realize pavement which reduces environmental load in terms of materials, and which uses high-durability concrete pavement in consideration of the lifecycle for both environmental and cost benefits.

Pervious concrete pavement (road usage/high-performance)
For test construction, concrete is manufactured at a ready-mixed concrete plant and transported using a few truck agitators. Leveling is performed using an asphalt finisher/paver and the surface is finished using a hand guide roller.

Early-opening-to-traffic cement concrete pavement (very high early strength, rapid-hardening, high early-strength)
>Onoda Chemico co., ltd
This concrete uses the very high early strength cement "Super Jet Cement" and is manufactured using the dedicated batching and mixing track mixer called the “Batcher-Jet-Mixer-Track” which is located on the construction site.
