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) This is the most common type of rigid pavement.
mechanized PCC pavement construction by eliminating the need for conventional side forms. Slipform paving resulted in higher productivity, better overall quality, and better-riding pavements. As the 21st century approaches, the slipform paver with modern computer controls still stands as the greatest paradigm shift in paving, and serves as the
Composite pavements consist of asphaltic concrete surface course over PCC or treated bases as shown in Figure 1-5. Composite pavements with PCC over asphalt are also being used. The treated bases may be either asphalt-treated base (ATB) or cement-treated base (CTB).
The Future of PCC Pavement Rehabilitation. Download our updated report: IS-117 Guidelines for Use of Asphalt Overlays to Rehabilitate PCC Pavements. Highlight features & benefits. Understand the rehabilitation process and the rehabilitation of PCC pavements with asphalt overlays. Mix design for asphalt overlays. Research backed by case studies:
In either approach, the service life must be estimated with sufficient accuracy and also the standard deviation and distribution must be esti- mated for the probabilistic approach. Recommendations for PCC/PCC composite pavement: 1. Service life (PCC layer structural life).
PCC/PCC composite pavements allow the pavement designer to design pavements using the best qualities of two different PCC mixes to produce a more functional and economical structure that generally is cost- effective in terms of service throughout its life.
This report documents recommendations for the design and construction of portland cement concrete (PCC) pavements. The recommendations were derived from the analysis of Long-Term Pavement Performance (LTPP) data.
