Add the following note: ITEM 898 QC/QA Concrete, Class QSC2, Superstructure (Deck), As Per Plan Smoothness: The following is to apply in lieu of the surface smoothness requirements per : Measure the highway surface smoothness in both wheelpaths for each proposed travel lane using an operator and equipment certified according to Supplement The wheelpaths are located parallel to the centerline of the highway and approximately 3.0- ft inside all lane edges, measured transversely. Measurement shall start approximately 250-ft before the approach slab/approach pavement interface at the entry end and continue to approximately 250-ft after the approach slab/approach pavement interface at the exit end. Ensure there is sufficient distance to get the profiler up to operating speed prior to initiating measurement. The bridge encounter will include 25-ft of approach pavement, entry approach slab, bridge deck, exit approach slab and 25-ft of exit pavement. Notify the engineer a minimum of 24 hours prior to road profile measurements. The engineer will verify the smoothness measuring equipment conforms to Supplement Do not perform any measurements until all concrete surfaces have reached specified curing and loading requirements. Remove all dirt and debris from the surface of the travel lanes prior to performing the surface smoothness measurements. Provide temporary pavement markings for all travel lanes that are of sufficient size to be visible during profiling measurements. Ensure the path of the profiler is parallel to the lane edges at all times during data collection

7 Provide the Engineer the International Roughness Index (IRI) using a continuous 25-ft base length analysis for each wheelpath and a Mean IRI (MRI) for each travel lane. Provide both IRI and MRI results for the entire length of the bridge encounter in accordance with ASTM E 1926 and Supplement The MRI is the average of the IRI values for the right and left wheel tracks in each travel lane. Corrective work is required for all localized areas of roughness with an IRI in excess of 400 inches per mile in any 25-ft interval along either wheel path of the bridge encounter. Corrective work is required for all travel lanes with an MRI in excess of 140 inches per mile along the entire length of the bridge encounter. If corrective work is required, develop a corrective work plan. Submit, to the Engineer: two copies of the corrective work plan; all IRI and MRI analyses; and all collected road profile in ProVAL compatible format. The engineer will submit one copy of the corrective work plan, all IRI and MRI analyses and all collected road profile data to the Office of Innovation, Partnerships, & Energy; Attn.: Infrastructure Management Section, 1980 W. Broad St., Columbus, OH Do not begin corrective work until receiving the Department s approval of the corrective work plan. All costs associated with the verification and correction of the surface smoothness is to be considered incidental to the work. Pay Factor: The Department will calculate the final adjusted payment according to and include the approach slab concrete and deck concrete in the same lot to determine the final pay factors. ITEM 898 QC/QA Concrete, Class QSC2, Superstructure (Approach Slabs), As Per Plan Smoothness: Requirements for smoothness verification and correction are included in ITEM 898 QC/QA Concrete, Class QSC2, Superstructure (Deck), As Per Plan. Miscellaneous: The Department will calculate the final adjusted payment according to and include the approach slab concrete and deck concrete in the same lot to determine the final pay factors. 18.
