330 SURFACE REQUIREMENTS. (REV 2- 13 -06) (FA 3 -8 -06) (7 -06) ARTICLE 330 -12 (Pages 239 -242) is deleted and the following substituted: 330 -12 Surface Requirements. 330 -12.1 General: Construct a smooth pavement with good surface texture and the proper cross - slope. 330 -12.2 Texture of the Finished Surface of Paving Layers: Produce a finished surface of uniform texture and compaction with no pulled, torn, raveled, crushed or loosened portions and free of segregation, bleeding, flushing, sand streaks, sand spots, or ripples. Correct any area of the surface that does not meet the foregoing requirements in accordance with 330 - 12.5.1 . (� Do not use asphalt concrete mixtures containing aggregates that cause a different color appearance in the final wearing surface in sections less than 1 mile [1 .5 km] in length and across the full width of the roadway unless approved by the Engineer. 330 -12.3 Cross Slope: Construct a pavement surface with cross slopes in compliance with the requirements of the Contract Documents. Furnish a level with a minimum length of 4 feet [1.2 m] or a digital measuring device approved by the Engineer for the control of cross slope. Make this level or measuring device available at the jobsite at all times during paving operations. Utilize electronic transverse screed controls on the paving machine (unless directed otherwise by the Engineer) to obtain an accurate transverse slope of the pavement surface. 330- 12.3.1 Quality Control Requirements: Measure the cross slope of the pavement surface by placing the measuring device perpendicular to the roadway centerline. Report the cross slope to the nearest 0.1 %. Record all the measurements on an approved form and submit to the Engineer for documentation. Measure the cross slope at a minimum frequency of one measurement every 100 feet [30 ml during paving operations to ensure that the cross slope is uniform and in compliance with the design cross slope. When the difference between the measured cross slope and the design cross slope exceeds ± 0.2% for travel lanes (including turn lanes) or ± 0.5% for shoulders, make all corrections immediately to bring the cross slope into the acceptable range. When the cross slope is consistently within the acceptable range, upon the approval of the Engineer, the frequency of the cross slope measurements can be reduced to one measurement every 250 feet [70 m] during paving operations. 330 - 12.3.2 Verification: The Engineer will verify the Contractor's cross slope measurements by randomly taking a minimum of ten measurements of the cross slope over a day's production. If the average cross slope of the ten random measurements varies more than the allowable tolerance from the design cross slope (0.2% for travel lanes including turn lanes and 0.5% for shoulders), take immediate action to bring the cross slope into the acceptable range. A recheck of the cross slope will then be made following the adjustment. If the recheck indicates that the cross slope is still out of tolerance, stop the paving operations and correct the deficient section in accordance with 330 - 12.5.1. Resume paving operations only upon approval of the Engineer. The Engineer reserves the right to verify the pavement cross slope at any time by taking cross slope measurements as described above.
