I 1 Surface Smoothness 2 Operate the inertial profiler in accordance with AASHTO R 57. Collect two longitudinal I 3 4 traces, one in each wheel path. Collect the control profile at locations designated in Table 2 prior to any pavement rehabilitation Work on the areas to be tested. Collect an acceptance 5 profile at locations designated in Table 2 after completion of all cement concrete pavement 6 grinding on the project. Profiles shall be collected in a continuous pass including areas I7 excluded from pay adjustments. Provide notice to the Engineer a minimum of seven 8 calendar days prior to testing. 9 Table 2 Locations Requiring MRI Testing Travel lanes where cement concrete grinding is shown in the Control profile plans Additional locations designated by the Engineer Control profile Travel lanes with completed cement Acceptance profile concrete pavement grinding Bridges, approach panels and 0.02 miles before and after bridges and approach panels and other Control and acceptance profile excluded areas within lanes requiring testing Ramps, Shoulders and Tapers Do not test I10 11 Within 30 calendar days after the Contractor's testing, the Engineer may perform 12 verification testing. If the verification testing shows a difference in MRI greater than the 10 13 percent, the following resolution process will be followed: I 14 15 1. The profiles, equipment and procedures will be evaluated to determine the cause 16 of the difference. I17 18 2. If the cause of the discrepancy cannot be resolved the pavement shall be retested 19 with both profilers at a mutually agreed time. The two profilers will test the section II 20 within 30 minutes of each other. If the retest shows a difference in MRI equal or 21 greater than the percentages shown in Table 2 of AASHTO R 54 the Engineer's 22 test results will be used for pavement smoothness acceptance. I23 24 The Contractor shall evaluate profiles for acceptance or corrective action using the current 25 version of ProVAL and provide the results including the profile data in unfiltered electronic 26 Engineering Research Division (ERD) file format to the Engineer within 3 calendar days of I27 completing each days profile testing. If the profile data files are created using an export 28 option in the manufacturer's software where filter settings can be specified, use the filter 29 settings that were used to create data files for certification.
