1 The inertial profiler operator shall be certified as required by AASHTO R 56 within three <br /> 2 years preceding profile measurement. <br /> 3 <br /> 4 Equipment or operator certification by other states or a profiler certification facility will be <br /> 5 accepted provided the certification meets the requirements of AASHTO R 56. <br /> 6 Documentation verifying certification by another state shall be submitted to the Engineer <br /> 7 a minimum of 14 calendar days prior to profile measurement. Equipment certification <br /> 8 documentation shall include the information required by part 8.5 and 8.6 of AASHTO R <br /> 9 56. Operator documentation shall include a statement from the certifying state that <br /> 10 indicates the operator is certified to operate the inertial profiler to be used on the project. <br /> 11 The decision whether another state's certification meets the requirements of AASHTO R <br /> 12 56 shall be vested entirely in the Engineer. <br /> 13 <br /> 14 5-05.3(4) Measuring and Batching Materials <br /> 15 Item number 2 is revised to read: <br /> 16 <br /> 17 2. Batching Materials — On all projects requiring more than 2,500 cubic yards of <br /> 18 concrete for paving, the batching plant shall be equipped to proportion aggregates <br /> 19 and cement by weight by means of automatic and interlocked proportioning devices <br /> 20 of accepted type. <br /> 21 <br /> 22 5-05.3(4)A Acceptance of Portland Cement Concrete Pavement <br /> 23 This section's title is revised to read: <br /> 24 <br /> 25 Acceptance of Portland Cement or Blended Hydraulic Cement Concrete <br /> 26 Pavement <br /> 27 <br /> 28 The first sentence is revised to read: <br /> 29 <br /> 30 Acceptance of portland cement or blended hydraulic cement concrete pavement shall be <br /> 31 as provided under statistical or nonstatistical acceptance. <br /> 32 <br /> 33 5-05.3(7) Placing, Spreading, and Compacting Concrete <br /> 34 This section's content is deleted. <br /> 35 <br /> 36 5-05.3(10) Tie Bars and Corrosion Resistant Dowel Bars <br /> 37 The first sentence of the last paragraph is revised to read: <br /> 38 <br /> 39 The tie bar holes shall be clean before grouting. <br /> 40 <br /> 41 5-05.3(12) Surface Smoothness <br /> 42 This section is revised to read: <br /> 43 <br /> 44 Pavement surface smoothness for this project will include International Roughness Index <br /> 45 (IRI)testing. The Contractor shall perform IRI testing on each through lane, climbing lane, <br /> 46 and passing lane, greater than 0.25 mile in length and these lanes will be subject to <br /> 47 incentive/disincentive adjustments. Ride quality will be evaluated using the Mean <br /> 48 Roughness Index (MRI) calculated by averaging the IRI data for the left and right wheel <br /> 49 path within the section. <br /> 50 <br /> 51 Ramps, shoulders and tapers will not be included in MRI testing for pavement smoothness <br /> 52 and will not be subject to incentive adjustments.
