8−114 repaired deck surfaces until the concrete has reached a minimum of 95 percent of its twenty-eight
28.day compressive design strength.
818.04 METHOD OF MEASUREMENT. "Portland Cement Concrete Deck Repairs (Partial Depth
Removal)" and "Portland Cement Concrete Deck Repairs (Full Depth Removal)" will be measured by the number square feet of such repairs actually made in accordance with the Plans and/or as directed by the Engineer.
818.05 BASIS OF PAYMENT. The accepted quantities of "Portland Cement Deck Repairs (Partial
Depth Removal)" and "Portland Cement Concrete Deck Repairs (Full Depth Removal)" will be paid for at the respective contract unit prices per square foot as listed in the Proposal. The prices so- stated constitute full and complete compensation for all labor, tools, materials and equipment, and all incidentals required to finish the work, complete and accepted by the Engineer. Supplemental reinforcing bars shall be paid for separately by force account in accordance with the provisions of Subsection 109.04 of these Specifications.
a.Reinforcing Bar Clearances . Existing reinforcing steel clearances indicated on the contract drawings are nominal and may vary due to the as-built conditions. An adjustment in the bid price for partial depth removal based on the percentage increase in depth of removal will be made should concrete need to be removed beyond the depth indicated by the contract drawings.
819.01 DESCRIPTION. This work consists of the setting of reinforcing bar dowels in existing
concrete or granite at the locations indicated on the Plans or as directed by the Engineer, all in accordance with these Specifications. 819.02 MATERIALS.
819.02.1 Reinforcing Dowels. Reinforcing dowels shall conform to the requirements of Subsection M.05.01; Bar Reinforcement , of these Specifications.
819.02.2 High Strength Non-Shrink Grout. High strength non-shrink grout shall be suitable for
outdoor use, and it shall have a minimum compression strength of 8,000 psi after 28 days as determined by testing under ASTM C109. It shall not exhibit any measurable decrease in volume after curing. All grout materials shall be listed on the Department's Approved Materials List. 819.03 CONSTRUCTION METHODS. Holes for the dowels shall be drilled at the designated locations. The diameter of the holes and the embedment lengths shall be as indicated in the following table: 8−115 Size of Bar Min. Hole Dia. (in.) Min. Embedment Length (in.) #4 1¼ 8 #5 1 1/8 1 0 #6 1½ 12
819.04 METHOD OF MEASUREMENT. "Drill and Grout Dowels" will be measured by the number
of dowels actually installed in accordance with the Plans and/or as directed by the Engineer. 819.05 BASIS OF PAYMENT. The accepted quantity of "Drill and Grout Dowels" will be paid for at the contract unit price per each as listed in the Proposal. The price so-stated constitutes full and complete compensation for all labor, materials, equipment, tools, and all incidentals required to finish the work, complete and accepted by the Engineer. The cost for furnishing the dowels shall be included in the appropriate reinforcing steel item as listed in the Proposal. SECTION 820 CONCRETE SURFACE TREATMENT PROTECTIVE SEALER
