513.5 -OPENING TO TRAFFIC : No traffic will be permitted on the cross -stitched pavement until the anchoring material can be expected, as shown by test data supplied by the anchoring material Manufacturer from an Independent Approved Laboratory, to have a compressive strength of at least 2,000 psi, unless otherwise approved by the Engineer.
513.6 -METHOD OF MEASUREMENT : Concrete pavement cross stitching is measured by each deformed bar installed and accepted.
289 513.7 -BASIS OF PAYMENT : The contract unit price paid for each deformed bar includes full compensation for furnishing and placing all the materials and the cost of all labor, tools, equipment, supplies, and incidentals necessary to complete the work in an acceptable manner. No payment will be made for items required by the Engineer to repair damage to the adjacent pavement incurred during drilling.

290 SECTION 514 ROLLER COMPACTED CONCRETE
514.1 -DESCRIPTION : Roller Compacted Concrete (RCC) consists of aggregate, Portland cement and possibly other supplementary cementitious mater ials (fly ash, slag), and water. RCC is proportioned, mixed, placed, compacted, and cured in accordance with these specifications. Ensure that the RCC conforms to the lines, grades, thickness, and typical cross section shown in the plans or otherwise est ablished by the WVDOH. When used as base course, it shall be constructed as shown in the plans.
514.2 -MATERIALS : Materials shall conform to the requirements of the following Subsection of Division 700:
MATERIAL SUBSECTION Coarse Aggregate 703.1 -4 Curing Materials 707.6 -707.10 Fine Aggregate Note 1 702.1 Portland Cement 701.1, 701.3 Pozzolanic Additives 707.4 Water 715.7 Water Reducing and Retarding Admixtures 707.2 Note 1 The use of limestone as fine aggregate will not be permitted
Shipping and storage of Cement and Pozzolanic Additives: Cement and pozzolanic additives shall be shipped and stored as outlined in Section 501.2.
514.2.1 -Material Requirements: Aggregates: Use no aggregate where the plasticity index of the aggregate exceeds 5. Aggregates may be a blend of fine and coarse aggregates. Use well -graded aggregate without gradation gaps and conforming to the following gradation:
Sieve Size % Passin g by Weight 1 inch 100 3/4 inch 95-100 1/2 inch 70-90 3/8 inch 60-85 #4 40-60 #16 20-40 #100 3-15 #200 0-8
Prior to the start of each day’s production, the Contractor shall perform a gradation test on the material to be used that day in order to verify that the aggregate gradation meets the above requirements. If the results of this test show that the aggregat e gradation does not meet the above requirements, the Contractor shall immediately notify the Engineer and shall not begin
