Section 501.—RIGID PAVEMENT

Revised 10 July 2014

INCLUDE THE FOLLOWING FOR COLORED SEALANT, AS APPROPRIATE

$$501.02A

501.02. Add the following:

$$501.02B

Furnish joint sealant material conforming to Subsection 712.01(e) that is a (insert color) color matching the color of the existing pavement.

$$501.02C

Furnish joint sealant material conforming to Subsection 712.01(f) that is a (insert color) color matching the color of the existing pavement.

INCLUDE THE FOLLOWING FOR STEEL PLATES, $$501.14B IS USED

$$501.02D

Furnish steel plates and keep available on the project for emergency use.

INCLUDE THE FOLLOWING FOR ACCELERATED FULL-DEPTH REPLACEMENT

$$501.03A

Add the following after Subsection 501.03:

501.03A Accelerated Full-depth Patching. Design the concrete mix according to Subsection 552.03 and conform to Table 501-1A. Make test specimens according to AASHTO T 23, except keep specimens in molds until tests are conducted after a 7-hour cure.

INCLUDE THE FOLLOWING FOR COLORED PAVEMENT (IF $$501.03A IS INCLUDED, CHANGE COLORED PAVEMENT SUBSECTION # 501.03A TO 501.03B)

$$501.03B

Add the following:

501.03A Pavement Containing Color. Prepare 6-foot by 6-foot by 4-inch (2 by 2-meter by 10 centimeter) test panels at an area near the project designated by the CO. Do not begin concrete pavement work until the CO inspects and approves the appearance of the test panels and the concrete mix design 28 calendar days after the test panels are constructed. The use of high range water reducer or accelerator in the test panel is prohibited.

INCLUDE THE FOLLOWING FOR FULL-DEPTH REPLACEMENT OR SMALL QUANTITY OF RIGID PAVEMENT (SEE $$501.12A)

$$501.11A

501.11. Add the following to the first paragraph:

Seal joints within 5 calendar days after patching to prevent spalling.

$$501.12A

501.12. Add the following:

For full depth replacement or small individual areas of rigid pavement (less than (insert quantity, to be determined during design & review) square yards (square meters)), meet the requirements of (c) below.

INCLUDE THE FOLLOWING IF APPLICABLE

$$501.13A

501.13. Add the following:

Schedule the patching operation so that all areas where the pavement has been removed are repaired during the same work period and the roadway opened to traffic according to Section 156. Complete all concrete operations sufficiently before opening the lane to traffic to allow the concrete to have attained sufficient strength to support traffic according to Subsection501.14. In case of emergency, temporarily fill and plate the repair areas according to Subsection 501.14.

INCLUDE THE FOLLOWING FOR ACCELERATED FULL-DEPTH REPLACEMENT

$$501.14A

501.14. Add the following:

For accelerated full-depth patches, do not allow traffic on new pavement until the minimum compressive strength has reached 1,200 pounds per square inch (8 MegaPascals) according to AASHTOT22.

INCLUDE THE FOLLOWING, IF APPLICABLE

$$501.14B

501.14 Add the following:

If an emergency or unforeseen circumstance prevents the completion of a pavement patch before opening the roadway, backfill and compact the excavation with aggregate base and cover with a steel plate so that the lane can be immediately opened to traffic. At the beginning of the next day's work, completely remove the aggregate, in a manner which will not disturb the subgrade or any dowels, load transfer tie bars, or load transfer assemblies which may have been previously placed.

Place steel plates over concrete patches only if the concrete has not developed sufficient strength as determined by the CO.

INCLUDE THE FOLLOWING FOR ACCELERATED FULL-DEPTH REPLACEMENT

$$501.15A

501.15. Add the following:

If accelerated full-depth patching is performed, conduct field control tests for concrete compressive strength, and gradation and moisture control of coarse and fine aggregate. Should the mix be of a questionable nature or the previous patches show poor performance, the CO may require that test cylinders be made, cured according to Subsection 552.15, and tested for a 7-hour minimum compressive strength of 1,200 pounds per square inch (8 MegaPascals). The minimum test frequency for slump and air content will be 1per 20 cubic yards (15 cubic meters). Conduct compressive strength tests as required by the CO. Conduct tests for gradation and moisture content daily before production. Concrete compressive strength will be evaluated under Subsection 106.05 and the maximum pay factor for concrete compressive strength will be 1.0.

INCLUDE THE FOLLOWING IF CONCRETE QUANTITY < 250 YD3 (190 m3)

$$501.15B

501.15. Delete the fourth paragraph, the last sentence in both (a) and (b), and all of (c). Substitute the following for the fourth paragraph:

Concrete compressive strength, pavement thickness, and pavement smoothness, will be evaluated under Subsection 106.04. Determine pavement smoothness according to Subsection 501.12. See Table 501-3 for minimum sampling and testing requirements for compressive strength and pavement thickness.
