Almost all rigid pavement is made with Portland Cement Concrete (PCC). Rigid pavements are differentiated into three major categories by their means of crack control: Jointed plain concrete pavement (JPCP)
For a typical single-layer PCC pavement, the effective dynamic k-value is obtained by first determining the deflection profile of the PCC surface using an elastic layer pro- gram, modeling all layers specified for the design (Figure 3.37).
Table 3.15 is a summary of relevant best practices and related specification require- ments for unbonded concrete overlays. Three major practices are featured: (1) existing pavement and preoverlay repairs, (2) overlay thickness and joint details, and (3) inter- layer requirements.
The PCC substructure is the primary load-carrying layer and is designed to provide a durable, long- lasting pavement with low fatigue damage and a strong base, whereas the HMA layer is primarily a functional layer with excellent surface characteristics that can be renewed rapidly. history HMA/PCC composite pavements are by no means a recent ...
The Long-Term Pavement Performance (LTPP) database provides data suitable for developing predictive models for Portland cement concrete (PCC) materials, stabilized materials, and unbound materials, as well as other design-related inputs for the MEPDG.
“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 surface characteristics; “curing” is the maintenance ...
Construction Joints. Expansion, isolation and construction joints are created by formwork before the PCC is placed. Since these joints are designed to completely separate adjacent masses of PCC, they are usually made by inserting a small non-PCC piece of material such as a strip of wood.
