Concrete Paving

There are 3 types of concrete pavements:

1. jointed plain (JPCP)

The majority if U.S. state agencied used this method of paving. Spacing betwwen joints is 15 feet and 7-12 inches thick. No steel reinforcement is used. Smooth steel bars may be used in transverse joints with deformed steel bars in longitudinal joints. The concrete usually cracks at the joints and not in other parts of the slab.

2. jointed reinforced (JRCP)

Rarely used today, this type of paving was used during the interstate development in the Eastern and Midwestern U.S.  It is no longer recommended since JPCP offers better performance and easier repair. In JRCP the spacing between joints is 30 feet or more. The cement contains a steel mesh reinforcement to hold together intermediate cracks in the slab.

3. continuously reinforced (CRCP)

Contains enough steel so that cracks will be held together. Cracks are expected and considered in the design process.

It costs more for continuous reinforcement of the pavement because of the cost of increased steel in the building, however the concrete lasts much longer. May be be chosen for heavy urban corridors.

Porous concrete

Porous concrete a type of porous paving surface, like porous asphalt, can bear frequent traffic, and is universally accessible. Its quality depends on the installer's knowledge and experience.
