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.
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 ...
PCC – Portland Cement Concrete. PCC is rigid and more durable than flexible asphalt pavement, and as such, is a pavement alternative for areas affected by heavy wheel loads from buses, garbage trucks and service vehicles. Potholes – bowl-shaped holes caused by water damage that may extend into the base.
Even though the industry has defined improved terminology and definitions for concrete overlays, these original terms are still widely used and are described below: â ¢ Unbonded concrete overlays consist of a portland concrete cement (PCC) layer constructed on top of an existing PCC pavement, separated by a bond breaker. â ¢ Bonded concrete ...
PCC/PCC composite pavements are becoming more common as the techniques are refined further. European research related to PCC/PCC composite pavements includes construction techniques and the use of recycled materials in the lower layer.
The history of portland cement concrete over portland cement concrete (PCC/PCC) composite pavements in the United States dates back to the first concrete pavement constructed in the United States, located in Bellefontaine, OH, in 1891, shown in Figure 1. Figure 1. The first PCC/PCC composite pavement in the United States in Bellefontaine, OH.
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.
