Three Myths About Contraction Joints in Residential Slabs

For plain and reinforced concrete, the slab-on-ground may be isolated or monolithic with the footing. When isolated, the first joint next to the footing can have a spacing up to that given in Table 1. For example, if slab thickness is 4 inches, the first joint can be 11.5 feet away when using concrete with ¾-inch maximum size aggregate.

Pavement condition index - Wikipedia

The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section.The PCI is widely used in transportation civil engineering and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service. It is a statistical measure and requires manual survey

Tie Bars - Pavement Interactive

Tie bars are typically used at longitudinal joints (see Figure 1) or between an edge joint and a curb or shoulder. Typically, tie bars are about 12.5 mm (0.5 inches) in diameter and between 0.6 and 1.0 m (24 and 40 inches long). Figure 1. Tie Bars Along a Longitudinal Joint.

Continuously Reinforced Concrete Pavement (CRCP) - ACPA Wiki

Continuously reinforced concrete pavements (CRCP) is a type of concrete pavement that does not require any transverse contraction joints. Transverse cracks are expected in the slab, usually at intervals of 1.5 - 6 ft (0.5 - 1.8 m). CRCP is designed with enough embedded reinforcing steel (approximately 0.6-0.7% by cross-sectional area) so that

FDM 14-10-5 Concrete Pavement Design August 17, 5.1 Standard Pavement Type Department policy establishes jointed plain concrete pavement with dowels as the standard type of concrete pavement to be used on highways in Wisconsin. Details for this type of concrete pavement are shown in SDD 13C11 and . SDD 13C13.

EverFE: Software for the 3D Finite Element Analysis of

EverFE (current version 2.24) is a user-friendly 3D finite-element analysis tool for simulating the response of jointed plain concrete pavement (JPCP) systems to axle loads and environmental effects. EverFE is useful for both concrete pavement researchers and designers who must perform either complex nonlinear or simple linear stress analyses

significantly, they can drastically increase the joint spacing to 10 to 30m. Dowel bars are required for load transfer. Reinforcements help to keep the slab together even after cracks Continuously reinforced concrete pavements (CRCP) is a type of concrete pavement that does not require any transverse contraction joints.


JPCP - Jointed Plain Concrete Pavement 2. JRCP [Jointed Reinforced Concrete Pavement] 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
