Doweling Concrete Joints

Doweling Concrete Joints

Doweling Concrete Joints

(OP)
I desire to dowel the concrete joints for a 10" thick concrete pavement for a transfer station. The trucks will be running in multiple directions throughout the lot, and the pavement will need to be poured in sections in various directions. Unlike a road where there is a longitudinal tie joint and transverse joints, I would like to dowel the concrete along all joint directions the same as there is multiple traffic patterns throughtout the lot. The lot will need to be done in at least 4-5 pours to maintain the use of the lot.

1. Can the contractor form along the proposed joints and set dowel inserts along the edge of the form to enable future insert of the dowel? How is this best done? Also due to the thickness, should I provide a keyway between the pours?

2. I often see concrete joints in new construction terminate perpendicular to the curbing to enable saw cutting the curb with the pavement. Is this necessary for the new pavement where it will terminate along existing concrete since there will be an expansion joint?

3. There is an existing fuel island in the middle of the lot set on a concrete pad. Some of this concrete is cracked. What is preferred manner to terminate along this existing concrete? Should I drill and set new dowels, pour a thickened slab and have an isolation joint? What is recommended at this location.

4. There is a lot to match and I did the best I could with the joint plan. Any suggestions? Slabs range from 12.5' to 15' max.
