Missouri's jointed plain concrete pavement (JPCP) design compares very favorably with other States' long life (40+ years) pavement designs. Continuously reinforced concrete pavement (CRCP) with specific design features has maintenance-free characteristics that, …
The Concrete Pavement Guide (CPG) provides a comprehensive overview of current new construction-reconstruction, preservation, and rehabilitation strategies used by the Department for concrete pavement. The information in this guide applies to all concrete pavement and composite pavement that was not previously cracked and seated.
Jointed Reinforced Concrete Pavement . JRCP contains steel mesh reinforcement (sometimes called distributed steel). In jointed reinforced concrete pavements, designers increase the joint spacing purposely, and include reinforcing steel to hold together intermediate cracks in each slab. The spacing between transverse joints is typically 30 feet ...

concrete pavement specifications. Reinforced concrete contains steel wire mesh intended to tightly hold together any cracks that occur. The steel mesh does not add any structural capacity and does not impact the thickness design. A reinforced pavement is the same thickness as a non-reinforced …
Continuously reinforced concrete pavement (CRCP) was introduced in the United States almost 100 years ago when the U.S. Bureau of Public Roads (now the Federal Highway Administration) constructed a CRCP test section on Columbia Pike in Arlington, ia.

Concrete parking lots have many similarities to other types of concrete pavement. On the other hand, parking lots differ from other pavements in that most of the area is in-tended for storage of vehicles and other goods rather than for movement of vehicles. The design of concrete parking lots should follow generally accepted procedures for con-

for reinforced concrete pavement on a stabilized used with figure 13-2 to design the reinforced foundation, it is first necessary to determine the concrete pavement in the same manner discussed thickness of plain concrete pavement required over above for nonstabilized foundations. 13-4 Change 2 *U.S. G.P.O.:1993-300-723:80080
4.7 Jointed Reinforced Concrete Pavement (JRCP) JRCP uses contraction joints and reinforcing steel to control cracking. Transverse joint spacing is longer than that for concrete pavement contraction design (CPCD) and, in Texas, it typically ranges from 30 ft. to 60 ft.
Please contact the Pavement Design Unit at 860-594-3287 if you have any questions.

Concrete pavement design features that reduce slab stresses and deflections and are also applicable to PCP systems are discussed in the following sections. Concrete Slab Thickness For major urban and rural highways, a minimum slab thick- ness of 10 in. (250 mm) should be considered for jointed sys- tems.
Apply AASHTO procedure to design a concrete pavement slab thickness for ESAL = 11 x 106. The design reliability is 95% with a standard deviation of 0.3. The initial and terminal serviceability levels are 4.5 and 2.5, respectively. Other design parameters are Ec = 5 x 106 psi, c = 650 psi, J = 3.2, Cd = 1.0 and k = 72 pci.

2. Rigid Pavement: Portland cement concrete (PCC) pavements; Called "rigid" since PCC's high modulus of elasticity does not allow them to flex appreciably; About 6.5% of paved U.S. roads use rigid pavement; It's Types: Jointed Plain Concrete Pavement (JPCP) Continuously Reinforced Concrete Pavement (CRCP) Pavement Design: 1.
The jointed reinforced concrete pavement is a modified or developed version of jointed unreinforced concrete pavement. It is used instead of plain concrete pavement when there is doubt regarding materials and workmanship and differential settlement are anticipated.
PAVEMENT DESIGN Subbase Effects The current Design does not model the contribution of bases accurately. At the AASHO Road Test, it was found that the concrete pavements with granular bases could carry about 30% more traffic. The current design procedures allows concrete pavements built with granular bases to carry about 5 - 8% more traffic.

Continuously reinforced concrete pavement (CRCP, see Figure 1) does not require any contraction joints. Transverse cracks are allowed to form but are held tightly together with continuous reinforcing steel.Research has shown that the maximum allowable design crack width is about 0.5 mm (0.02 inches) to protect against spalling and water penetration (CRSI, 1996 [1]).
third type, jointed reinforced concrete pavement (JRCP), incorporates wire mesh reinforcement equaling about 0.2 percent of the cross-sectional area of the concrete; however, it is no longer widely used for highway pavements in the U.S. The basic features of these three concrete pavement types are shown in Figure 1.
