19、TIES GUIDE SPECIFICATIONSReferences are in agreement with UMRL dated October 2008*SECTION 32 13 16.16ROLLER COMPACTED CONCRETE (RCC) PAVEMENT11/08*NOTE: This guide specification covers the requirements for roller compacted concrete (RCC) pavements for airfields, roads, streets, parking areas, repair
20、 yards, open-storage areas, and other utility grade pavements.Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable item(s) or insert appropriate information.Remove information and requirements not required in re
21、spective project, whether or not brackets are present.Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the I
22、nternet.Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR).*PART 1 GENERAL*NOTE: In preparing contract specifications for RCC pavement construction, the Contracting Officer will use Appendix D of UFC 3-250-04FA for further guidance.Insert name and location of projec
23、t. Specification should be tailored for the specific site conditions, available materials, design requirements and construction practices.*SECTION 32 13 16.16 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-1.1 MEASUREMENT AND PAYMENT PROCEDURE
24、S*NOTE: The Designer must carefully correlate and edit the bid items, measurement and payment paragraphs, and all the technical paragraphs so use of Portland cement, pozzolan, Portland-pozzolan cement, and ground granulated blast furnace slag will be well coordinated. Do not permit use of ground sla
25、g with pozzolan or Portland-pozzolan cement. Either use no separate pozzolan or use only a reduced amount if Portland-pozzolan cement is used.Unit price bid items are recommended when the quantity of RCC and or the quantity of cementitious materials is not known or likely to be variable. If the quan
26、tity could range beyond 15 percent of the bid item, split bid items should be used. If quantities are known at the time of bidding, lump sum bid items are recommended.*1.1.1 Concrete Quantity1.1.1.1 Measurement of Concrete QuantityThe quantity of concrete to be paid for will be the number of cubic m
27、eters yards, rounded to the nearest tenth of a cubic meter yard, placed in the completed and accepted pavements, including the accepted test section. Payment will not be made for wasted concrete, for concrete used for the convenience of the Contractor, or for concrete outside the neat lines shown on
28、 the drawing. Concrete will be measured in the completed and accepted pavements in accordance with the dimensions shown in the plan and cross section. No deductions will be made for rounded or beveled edges or the space occupied by pavement reinforcement, dowel bars, tie bars, or electrical conduits
29、, nor for any void, drainage, or other structure extending into or through the pavement slab measuring 1 cubic meter 3 cubic feet or less in volume. No other allowance for concrete will be made unless placed in specified locations in accordance with written instructions previously issued by the Cont
30、racting Officer.1.1.1.2 Payment for Concrete QuantityThe quantity of concrete measured as specified above, will be paid for at the contract unit price when placed in completed and accepted pavements or, where appropriate, at reduced prices adjusted in accordance with paragraph PAYMENT ADJUSTMENT. Th
31、e unit price will include the cost of labor and materials and the use of equipment and tools required to complete the work, except the cement, pozzolan, or ground granulated blast furnace slag that is specified for separate payment.1.1.2 Cement Quantity1.1.2.1 Measurement of Cement QuantityThe quant
32、ity of cement to be paid for will be the number of metric tons tons of cement used in the completed and accepted pavements. Payment will not be made for wasted cement or for cement used for the convenience of the Contractor. The quantity to be paid for will be determined by multiplying SECTION 32 13
33、 16.16 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-the weight in kg pounds of cement required by the mixture proportions per cubic m yard by the number of cubic m yards of the various mixtures placed and measured for payment, then dividing
34、by 10002000 and rounding off to the nearest tenth of a metric ton ton.1.1.2.2 Payment for Cement QuantityThe quantity of cement, determined as specified above, will be paid for at the contract unit price, which includes all costs of handling, hauling, and storage at the site. Adjustment in unit pric
35、e because of requirements of paragraph PAYMENT ADJUSTMENT will not be made in the payment for Portland cement.1.1.3 Pozzolan Quantity*NOTE: This specification requires that pozzolan be used for all applications unless special circumstances exist. If pozzolan must be eliminated because it is not loca
36、lly and readily available or the available quality is unacceptable, remove this paragraph and all further reference to the material.*1.1.3.1 Measurement of Pozzolan QuantityThe quantity of pozzolan paid for will be the number of metric tons tons used as a cementitious material in the completed and a
37、ccepted pavements. Payment will not be made for wasted pozzolan or for pozzolan used for the convenience of the Contractor. The quantity to be paid for will be determined by multiplying the weight in kg/cubic meter pounds/cubic yard of pozzolan used as a cementitious material, and required by the mi
38、xture proportions by the number of cubic m yards of the various mixtures placed and measured for payment, then dividing by 1000 2000 and rounding off to the nearest tenth of a metric ton ton. Payment will not be made for pozzolan used strictly as a Contractors option to compensate for lack of fines
39、in the aggregate.1.1.3.2 Payment for Pozzolan QuantityThe quantity of pozzolan, determined as specified above, will be paid for at the contract unit price, which includes costs of delivery, handling, and storage at the site. Adjustment in unit price because of requirements of paragraph PAYMENT ADJUS
40、TMENT will not be made in the payment for pozzolan.1.1.4 Ground Granulated Blast Furnace Slag (GGBFS)*NOTE: If ground granulated blast furnace slag is not locally and readily available, remove this paragraph and all further reference to the material.*1.1.4.1 Measurement of GGBFS QuantityThe quantity
41、 of GGBFS to be paid for will be the number of metric tons tons of GGBFS used in the completed and accepted pavements. Payment will not be made for wasted ground iron blast furnace slag or for GGBFS used for the convenience of the Contractor. The quantity to be paid for will be SECTION 32 13 16.16 P
