Jointed Concrete Pavement (JCP) Steel & Joints in JCP: – Transverse joints spaced at regular intervals – Transverse joints used to control temperature induced contraction and expansion – Smooth dowel bars used at transverse joints for load transfer – …

Jointed plain concrete pavement (JPCP, Figure 1) uses contraction joints to control cracking and does not use any reinforcing steel. Transverse joint spacing is selected such that temperature and moisture stresses do not produce intermediate cracking between joints. This typically results in a spacing no longer than about 6.1 m (20 ft.).

JCP is an easy to design solution that can deliver over 50 years of successful service life. Dowel bars are used in pavements to withstand heavy loads and high traffic volumes with minimal joint faulting. JCP is a proven cost-effective pavement for long lasting highways and roads.

Jointed reinforced concrete pavements (JRCP) contain steel mesh reinforcement (sometimes called distributed steel). In JRCP, designers intentionally increase the joint spacing and include reinforcing steel to hold together mid-panel cracks. The spacing between transverse joints is typically 30 feet or more.

ADT and one-way total 18-kip ESALs are provided by the Transportation Planning and Programming (TPP) Division. Field performance evaluations of concrete pavement have revealed that the soundness of the base is essential to the long-term performance of concrete pavement.

concrete-surface pavements (JCP), including jointed concrete over-lays on PCC pavements. Each of the distresses has been grouped into one of the following categories: A. Cracking B. Joint Deficiencies C. Surface Defects D. Miscellaneous Distresses 1 DISTRESSES FOR PAVEMENTS WITH JOINTED PORTLAND CEMENT CONCRETE SURFACES

2016年2月18日 · JRCP designs contain both joints and reinforcement (e.g., welded wire fabric, deformed steel bars). Joint spacings are longer (typically about 9 to 12 m [30 to 40 ft]), and dowel bars and tie bars are used at all transverse and longitudinal joints, respectively.

Pavement Performance Program. Color photographs and drawings illustrate the distresses found in three basic pavement types: asphalt concrete-surfaced, jointed (plain and reinforced) portland cement concrete, and co. tinuously reinforced concrete. Drawings of …

Various pavement types can be used in the construction of roundabouts, including hot-mix asphalt pavement (HMAP), jointed concrete pavement (JCP), continuously reinforced concrete pavement (CRCP), and precast concrete pavement (PCP). This Tech Brief describes the application, design, and construction aspects of JCP roundabouts. Figure 2.
