CONTINUOUSLY REINFORCED CONCRETE PAVEMENT STATE STANDARDS--DESIGN AND CONSTRUCTION PRACTICES OF VARIOUS STATES

The data presented here were obtained from those states that have designed and constructed continuously reinforced concrete pavement (CRCP). Twenty-seven states are listed which specify thicknesses in the range of 6 inches CRCP for overlays to 11 inches full depth CRCP. Longitudinal steel percentages range from a low of 0.49 in a southern state to 0.70 in northern climates. A number of states have increased the steel percentage and now require the use of a more "non-erodable" stabilized subbase to control deflection and provide longevity of support under CRCP. Current requirements for internal vibration have been evaluated by several states. On thicker pavements, vibration frequencies above 8,000 vpm were required to adequately consolidate a slipform concrete mix, and produce a smooth surface within inspection tolerances. This report presents data under the following categories: CRCP Thickness--Longitudinal Steel; Method of Securing Longitudinal Splices; CRCP Thickness--Transverse Steel and Tiebars; Longitudinal Joints, Transverse Construction Joints, and Subbase Type, Width and Depth; Terminal Joints, Use of Slipform Paver and Method of Installing Steel; and Concrete Properties and Specifications: coarse aggregate, strength, mixing, truck hauling and placing requirements.
