257 When Item 501011 -* is specified in the project plans the quantity of concrete used in concrete overlays to be paid for will be the number of cubic yards in place and accepted. The Engineer will measure the volume of concrete used in concrete overlays using the Contractor’s certified batch tickets or other approved documentation. Bridge approach expansion joints will be measured separately and shall be the actual number of joints constructed, complete in place and accepted. In contracts where only widening is called for, the square yards of pavement widening will be determined from the length of strips, measured along the edges and upon the surface, times the width as measured at regular intervals, plus the area of any widening on curves, turnouts or intersections authorized and measured separately. No extra payment will be made for removing and crushing the existing pavement for use as coarse aggregate for concrete. No additional measurement is necessary nor will addition compensation be allowed for the placement of Safety Edge.
501.23 Basis of Payment :
501.23.1 General: The quantities, determined as provided above, will be paid for at the
contract unit prices less adjustments referred to below, which shall constitute full compe nsation for furnishing and preparing of all materials, including reinforcing steel, transverse and longitudinal joints, expansion joint filler, elastomeric joint seals, silicone sealant, epoxy mortar for joint repair work, polyethylene tape, rope or rod jo int back -up material, lubricant -adhesive for elastomeric seals, and dowels or load transfer devices as are required in the Plans; construction of any bond breaker/leveling course, milling existing surface; placing, finishing and curing concrete; and all la bor, equipment, tools, field laboratory, supplies and incidentals necessary to complete the work.
501.23.1 1-The measurements which represent the thickness of the sampling units shall
be analyzed to determine the average value of the pavement thickness. This value will be used to determine the degree of compliance with the provisions set forth in subsection
501.19 and to develop certain factors to be used in the derivation of equitable deductions
as set forth in subsection s 501.23.1.2 and 501.23.1.3, in the event the provisions of this Specification are not met. No payment will be made for pavement areas that ar e 0.922T or less in thickness, the area being defined in the manner set forth in subsection 501.19.2. Any area of pavement which is deficient in thickness by more than 0.7 inches and is considered by the Engineer to be inadequate to perform satisfactorily shall be removed and replaced at no added cost to the Division. The balance of the item, the portion of the item not treated in the manner set forth above, will be treated in the manner set forth in subsections 501.23.1.2 or
501.23.1 3.
501.23.1 2-When the average value of the pavement thickness is equal to or greater
than the specified thickness, the quantity of pavement represented by this average thickness will be paid at the contract unit price.
501.23.1 3 -When the average value of the pavement thickness is less than the specified
thickness, the fraction of pavement having a thickness greater than 0.922T will be paid for at a unit price as set forth in the following schedule, and no payment will be made for the remainder of the pavem ent being considered. SCHEDULE OF UNIT PRICES Average Value of Pavement Thickness Unit Price as Percent of Contract Unit Price 0.01 to 0.10 inches Less Than Specified Thickness 98.0 0.11 to 0.20 inches Less Than Specified Thickness 96.0 0.21 to 0.30 inches Less Than Specified Thickness 94.0 0.31 to 0.40 inches Less Than Specified Thickness 92.2 0.41 to 0.50 inches Less Than Specified Thickness 90.3 0.51 to 0.60 inches Less Than Specified Thickness 88.4 0.61 to 0.70 inches Less Than Specified Thickness 86.5 More than 0.70 inches Less Than Specified Thickness 0.0
