Smoothness pay adjustments will only be applied when the smoothness is measured by an inertial profiler in accordance with 501.25(a). 650
The Mean Roughness Index, MRI, will be determined utilizing a fixed interval for each lane for each 0.1-mile section of paving. The MRI for a 0.1-mile section is the average of the IRI of the two-wheel pa ths. A Quality Assurance Pay Factor, PFs, for smoothness will apply to the planned thickness of the PCCP. The quality assurance adjustment for each section will be calculated by the following formula: 501.28 419 qs = (PFs – 1.00) x A x U
where: 660 qs = quality assurance adjustment for smoothness for one section PFs = pay factor for smoothness A = area of the section, sq yd U = unit price for the material, $/sq yd.
The quality assurance adjustment for smoothness, Qs, for the contract will be the total of the quality assurance adjustments for smoothness, qs, on each section by the following formula: 4V TV 670
When smoothness is measured by an inertial profiler, payment adjustments will be made for any 0.1-mile section based on the initial MRI generated and in accordance with the following table. The MRI pay factors for smoothness will be determined prior to any required smoothness correction in accordance with 510.25(d). Smoothness correction if required shall be in accordance with 501.25(d). For any 0.1-mile sections containing transverse construction joints that are required as per the planned maintenance of traffic, the pay factors for smoothness may be determined after corrective action at the discretion of the Contractor. Regardless of the tabulated value, the maximum pay factor for a smoothness section where corrective action has been 680 performed will be 1.00.

501.28 420 501.29 Appeals
If the Contractor does not agree with th e acceptance test results, a request may be made in writing for additional tests for a sublot or lot. The basis of the appeal shall include applicable QC test results showing acceptable quality results and shall be 690 submitted within five calendar days of receipt of the Department’s written results for that lot. Upon review of the appeal, th e Engineer may accept the PCCP in accordance with 105.03 or accept the appeal.
obtained from flexural strength testing indicate greater than a 50 psi difference between the Department’s and the Contractor’s test results. Once additional testing has been approved, the Contractor shall obta in cores, as directed, in the presence of the Engineer. 700 The Engineer will determine the location of the cores within the appealed and adjacent sublots using the same CMD. The lo cation of the cores will be at the center of a lane at the acceptance sample location. Cores shall not be taken over dowels or within 5 ft of a header. Two cores shall be taken in each sublot for the full depth of pavement and shall be 4 in. in diameter. All core holes shall be filled with portland cement concrete within 24 h of drilling. If adjacent sublots were produced using different CMDs, the matter will be adjudicated as a failed material in accordance with normal Department practice. 710 Each core will be tested for split tensile strength in accordance with ASTM C496. The cores will be submerged in lime saturated water prior to testing for a minimum of 40 h. The average core split tens ile strength will be determined for the appealed and adjacent sublots. Modulus of rupture will be calculated as follows:
»¼º «¬ª 2A2A 1A1A D DS2F S2F x S F
where: 720
FD = modulus of rupture of the appealed sublot FA1 = modulus of rupture of the previous adjacent sublot FA2 = modulus of rupture of th e subsequent adjacent sublot SD = split tensile strength of the appealed sublot SA1 = split tensile strength of the previous adjacent sublot SA2 = split tensile strength of the subsequent adjacent sublot. 501.29 421 2. Air Content Appeals will not be considered unless QC test results indicate greater than a 0.5% difference between the Department’s and th e Contractor’s tests. Once additional testing has been approved, the Contractor shall obtain core as directed in the presence of the Engineer. The Engineer will determine the location of the core within the appealed sublot. The location of the core will be at the center of a lane at the acceptance sample location. 730 A core shall not be taken over dowels or within 5 ft of a header. One 4 in. diameter full depth core shall be taken from the pa vement for each sublot appealed. All core holes shall be filled with PCC or rapid setting patch material within 24 h of drilling. The air content for a sublot will be the hardened concrete air content determined from the core in accordance with ITM 401. When ACBF aggregates are used, the hardened concrete air content will be de termined in accordance with ASTM C457.
The Department will perform annual Qua lity Assurance reviews of a portion of 740 each Contractor’s MRI results in accordance with ITM 917. The Contractor’s results will be compared to the Department’s. The Department will notify the Contractor of unacceptable results in a timely manner. The Department will allow an appeal period of 14 days during which time the Contractor must submit a written request and appeal results for Department review. If the Contractor’s appeal results do not agree with the Department’s results, the Contractor shall be required to perform a side-by-side evaluation. The Department’s results will be utilized for smoothness payment in place of the Contractor’s results unless the Contract or’s appeal results are determined to be acceptable for payment. Sections where corr ective action has taken place prior to the Department’s data collection will utilize the Contractor’s initial results prior to 750 corrective action for payment. 501.30 Method of Measurement QC/QA-PCCP will be measured by the square yard of the thickness specified. The area of QC/QA-PCCP will be the planned width of the pavement multiplied by the length of the pavement, or as directed in writing. The width of the pavement will be as shown on the typical cross-section of the plans. The length of the pavement will be measured parallel to the surface of the pa vement along the centerline of the roadway or ramp, excluding paving exceptions as shown on the plans. 760 Milled pavement corrugations will be measured in accordance with 606.02.
501.31Basis of Payment
The accepted quantities of QC/QA-PCCP will be paid for at the contract unit price per square yard for the thickness specified, complete in place. Payment for furnishing, calibrating, operating the inertial profiler, and furnishing IRI profile information will be made at the contract lump sum price for Inertial Profiler, PCCP. 501.31 422 770 Furnishing and operating the 16 ft straight edge shall be included in the cost of other pay items within this section. Adjustments to the contract payment due to measurements for modulus of rupture, thickness, air content, range and smoothness will be included in a quality assurance adjustment pay item in accordance with 109.05.1. Milled pavement corrugations will be paid for in accordance with 606.03. Payment for pavement thickness determinations will be made at the contract lump 780 sum price for coring, PCCP. A change order in accordance with 109.05 will be developed to adjust the cost of coring when the final QC/QA-PCCP quantity differs from the bid quantity by more than 2,400 sq yds. This adjustment covers the cost of cores for the adjusted quantity of QC/QA-PCCP. The adjustment, plus or minus, will be based on the difference in the number of sublots, rounded to the nearest full sublots, times $100.
