PCC Placement

PCC can be placed directly in the desired location by truck or truck attachments (see Figures 1 and 2), or can be fed into a placement machine for more accurate and even placement.  PCC that is moved excessively once it has been unloaded from the transport truck will tend to segregate (become less homogeneous).

Figure 1. Placement over dowel bars in an intersection.

Figure 2. Placement in front of a rolling screed.

During the screeding (or strikeoff) process, excess portions of the roughly placed PCC are cut off in order to bring the slab to the required elevation. This is usually done by dragging a straightedge across the slab at the required elevation.
