Due to the above reasons and many others several shear keys are provided over the cross sections. Retaining walls and traffic barrier details for reinforced concrete retaining walls are.

1 the bridge office has. Greased steel dowels are often cast horizontally into the wall to tie adjacent sections together. Typical control joint detail figure 16. Chapter 10 mass concrete p.

Ment should not pass through wall expansion or isolation joints. Vertical expansion joints are incorporated into the wall to account for expansion due to temperature changes. True expansion joints in cast in place walls are not common. Since we know the cohesion of the concrete and the surface area of the joint resisting force can be calculated.

Backfilling against reinforced concrete retaining walls shall not be permitted until the concrete has reached its 28 day strength. Construction joints use construction joints when the c o n c r ete placement. For cantilevered and gravity walls vertical expansion joint spacing shall be a maximum of 60 feet on. These joints may be filled with flexible joint fillers.

Chapter 9 liquid retaining structures p. Typical expansion joint detail backfill and drainage requirements. Expansion joints should be located at intervals up to 90 feet.
