40-1.04 PAYMENT

The Department does not pay for additional coring that you request to check dowel or tie bar alignment.

If the Engineer authorizes a test strip that remains in place as part of the pavement, the payment quantity for any type of concrete pavement includes the volume of the test strip.

The Department does not pay for additional tie bars required due to the curvature of the pavement slab.

Payment for grinding existing pavement is not included in the payment for concrete pavement.

40-2 CONTINUOUSLY REINFORCED CONCRETE PAVEMENT

40-2.01 GENERAL

40-2.01A Summary

Constructing continuously reinforced concrete pavement includes terminal joints, expansion joints, wide flange beam terminals and pavement anchors.

40-2.01B Definitions

40-2.01C Submittals

If you request to use plastic chairs to support the transverse bars, submit a sample of the plastic chair, including:

1. Manufacturer's instructions for the applicable use and load capacity

2. Chair spacing

3. Your calculation for the load on a chair for the area of bar reinforcement it supports
During production, submit the test data for the coefficient of thermal expansion as an informational submittal.

40-2.01D Quality Assurance

During the evaluation of the test strip, the Engineer visually checks the reinforcement and dowel and tie bar placement.

During production, test the coefficient of thermal expansion of the concrete at a frequency of 1 test for each 5,000 cu yd of paving but not less than 1 test for a project with less than 5,000 cu yd of concrete.

40-2.02 MATERIALS

40-2.02A General

40-2.02B Transverse Bar Assembly

Transverse bar assemblies may be used to support longitudinal bars instead of transverse bars and other support devices.

40-2.02C Wide Flange Beam

Wide flange beams and studs must be either rolled structural steel shapes complying with ASTM A36/A36M or structural steel complying with ASTM A572/A572M.

Polyethylene foam board for wide flange beams must be commercial quality.

40-2.02D Joints

Joint seals for wide flange beam terminals and for transverse expansion joints must comply with section 51-2.02.

Expanded polystyrene for transverse expansion joints and wide flange beam terminal must comply with section 51-2.01B(1).

40-2.03 CONSTRUCTION

40-2.03A General

Reserved

40-2.03B Bar Reinforcement

Place bar reinforcement under section 52-1.03D except you may request to use plastic chairs. Plastic chairs will be considered only for support directly under the transverse bars. You must demonstrate the vertical and lateral stability of the bar reinforcement and plastic chairs during the construction of the test strip.

For a transverse bar in a curve with a radius under 2,500 feet, place the reinforcement in a single continuous straight line across the lanes and aligned with the radius point as shown.

40-2.03C Construction Joints

Transverse construction joints must be perpendicular to the lane line. Construct the joints to allow for lap splices of the longitudinal bar.

Clean joint surfaces before placing concrete against the surfaces. Remove laitance, curing compound, and other foreign materials.

40-2.03D Wide-Flange Beams

Completely fuse studs to a wide-flange beam with an electric arc welder. Replace studs dislodged in shipping or that can be dislodged with a hammer.

40-2.03E Correcting Noncompliant Pavement Work

40-2.03E(1) General

The specifications for repairing cracks in section 40-1.03N do not apply to CRCP. Do not apply high-molecular-weight methacrylate to cracks in CRCP.

CRCP that develops raveling areas of 6 by 6 inches or greater requires partial depth repair. CRCP that develops one or more full-depth transverse cracks with faulting greater than 0.25 inch or one or more full-depth longitudinal cracks with faulting greater than 0.50 inch requires full-depth repair.

40-2.03E(2) Partial Depth Repair

Partial depth repair must comply with section 41-4 except:

1. Determine a rectangular boundary which extends 6 inches beyond the damaged area. The depth of the saw cut must be between 2 inches from the surface to 1/2 inch above the longitudinal bars.

2. Provide additional reinforcement if each length of the repair boundaries is equal to or greater than 3 feet.

40-2.03E(3) Full-Depth Repair

40-2.03E(3)(a) General

Remove the full-depth of CRCP except for the portion of reinforcement to remain in place. Provide continuity of the reinforcement. Splicing must comply with section 52-6. Do not damage the base, concrete, and reinforcement to remain in place. Place concrete in the area where you removed CRCP.

40-2.03E(3)(b) Transverse Cracks

Make initial full-depth transverse saw cuts normal to the lane line a distance of 3 feet on each side of the transverse crack.

40-2.03E(3)(c) Longitudinal Cracks

Remove the cracked area normal to the lane line for the full width of the lane a distance of 1 foot beyond each end of the crack. You may propose alternate limits with your repair plan.
