In pavement construction, three different concrete pavement design types are commonly used:

  1. Combined Plain Concrete Pavement (JPCP,
  2. Combined reinforced concrete pavement (JRCP), And
  3. Continuous reinforced concrete pavement (crcp,

Each of these design types can provide long-lasting pavements that meet or exceed specific project requirements. Each type is suitable for new construction, reconstruction and overlay (resurfacing) of existing roads.

1. JPCP [Jointed Plain Concrete Pavement]

Due to their cost-effectiveness and reliability, most concrete pavements manufactured today are JPCP designs. There is no reinforcement in them. Their transverse joints are usually less than 5 to 6.5 m (15 to 20 ft) apart. They may have dowel bars in transverse joints to transfer traffic loads across slabs and tie bars in longitudinal joints to promote total interlock between slabs.

2. JRCP [Jointed Reinforced Concrete Pavement]

The JRCP design consists of both joints and reinforcement (eg, welded wire fabric, deformed steel bar). The combined spacing is long (usually about 9 to 12 sq. m.). [30 to 40 ft]), and dowel bars and tie bars are used in all transverse and longitudinal joints, respectively.

Reinforcement, distributed throughout the slab, composes approximately 0.15 to 0.25 percent of the cross-sectional area and is designed to hold tightly together any transverse cracks that may develop in the slab. It is difficult to ensure that joints are cut where the reinforcement has come off. This sidewalk type is not as common as it once was on state highways, but it is used by municipalities to some extent.

3. CRCP [Continuously Rein­forced Concrete Pavement]

CRCP designs have no transverse joints, but do contain a significant amount of longitudinal reinforcement, typically 0.6 to 0.8 percent of the cross-sectional area. Transverse reinforcement is often used. The high content of reinforcement affects the development of transverse cracks within an allowable gap (approximately 0.9 to 2.5 m) [3 to 8 ft] separate) and serves to hold the cracks tightly together. Some agencies use CRCP designs for high-traffic, urban routes because of their suitability for high-traffic loads.
