Specifications include, but are not limited to: HMA Pavement.: a. Make corrections by diamond grinding, overlaying, replacing, or inlaying the area. If surface is corrected by diamond grinding, perform same work and use same equipment as specified for PCC pavement.; b. If surface is corrected by overlay, replacement, or inlay; begin and end surface correction with a transverse saw cut normal to pavement lane lines or edge lines within any one area. Profile of surface shall be smooth with no bumps or dips at beginning or end of correction.; c. Overlay correction shall be for entire pavement width. Pavement cross slope shall be maintained through corrected areas.; PCC Pavement.: Make corrections using an approved profiling device or by removing and replacing pavement. Apply corrective methods to full lane width. Ensure, when completed, corrected area (full lane width) has uniform texture and appearance, with the beginning and ending of the corrected area squared normal to centerline of paved surface. Where surface corrections are made, grooving will not be required.; Evaluate pavement smoothness for Interstate and Primary main line pavement surfaces, and other road surfaces included on Primary projects, except when specifically excluded or modified by the contract documents. Main line pavement is defined as permanent pavement for through lanes.; A. Index used for determining the pavement smoothness is the Mean Roughness Index (MRI) per segment as determined by latest version of the FHWA’s software, ProVAL.; B. The other measure of pavement smoothness is the Area of Localized Roughness (ALR) based on a continuous MRI computed over a 25 foot distance as determined by latest version of ProVAL.; C. A pavement segment is defined as a continuous area of finished pavement 0.1 mile in length and one lane (10 to 12 foot nominal) in width. A partial segment may result from an interruption of the continuous pavement surface (in other words, bridge approaches, side road tie-ins, the completion of the daily paving operations, and so forth). Pay adjustments will be prorated for partial segments. If a segment is less than 100 feet in length and requires corrective work, Engineer will waive corrective work requirement for segment and instead assess a prorated disincentive. Contracting Authority will subject the segment to ALR correction in accordance with Table 2317.05-1
