PCC Transport Pavement Interactive
In rigid pavement construction it is used in PCC for transport truck washing dust control and PCC curing. Additionally rain at the job site or along the PCC haul route can be a source of water. Finally water can also be used to control PCC workability. PCC performance is closely tied to its water-cement ratio and the amount of mixing water.

PCC Truck Mixer Pavement Interactive
PCC Truck Mixer Truck mixers are the most common mode of PCC transport. They consist of a truck-mounted drum that rotates on an inclined axis. A typical mixing truck (Figures 1 and 2) uses a 6.9 9.2 m 3 (9 12 yd 3) mixing drum the size being limited due to gross vehicle weight of the loaded truck.

Truck Mixed PCC Pavement Interactive
Truck mixed PCC (Figure 2) is appropriate for all types of pavement construction but is particularly well-suited for instances that can take advantage of a concrete mixing trucks monitored continuously agitated storage volume (the mixing drum) and its ability to precisely deliver PCC

Shrink Mixed PCC Pavement Interactive
Typically 1 m 3 (1.3 yd 3) of fully mixed PCC requires about 1.58 m 3 (2.07 yd 3) of individual ingredients (ACPA 1995 [1]). Thus with shrink mixing more PCC can be loaded into each truck mixer. Many central mixing plants use a stationary plant-mounted mixer to shrink mix PCC before charging their truck mixers.
