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). During the … Read more
PCC Paving Procedures
The general rigid pavement construction procedure involves placement, consolidation, finishing, curing and jointing in rapid succession. “Placement” involves any equipment or procedures used to place the delivered PCC on the desired surface at the desired thickness; “consolidation” involves any means used to eliminate undesirable voids; “finishing” involves any equipment or procedures used to impart desirable … Read more
PCC Finishing
Finishing involves all processes and equipment used to create the final surface finish and texture of fresh PCC. Generally, finishing can be divided into floating and texturing: Floating. A flat surface is run across the PCC in order to eliminate high and low spots, embed larger aggregate particles beneath the surface, remove slight imperfections and … Read more
Jointed Plain Concrete Pavement
Jointed plain concrete pavement (JPCP, Figure 1) uses contraction joints to control cracking and does not use any reinforcing steel. Transverse joint spacing is selected such that temperature and moisture stresses do not produce intermediate cracking between joints. This typically results in a spacing no longer than about 6.1 m (20 ft.). Dowel bars are … Read more
