sweeping operation immediate) after the milling operations or as <br /> Perform the p g p Y <br /> directed by the Engineer. <br /> 327-3 .2 Quality Control Requirements : Furnish an electronic level with a length of 4 <br /> feet and an accuracy of plus or minus 0 . 1 degree approved by the Engineer for the control of <br /> cross slope . Make this electronic level available at the jobsite at all times during milling <br /> operations . Calibrate and compare electronic levels in accordance with 330 - 12 . 3 . 1 at a minimum <br /> frequency of once per day before any milling operation. <br /> Multiple cuts may be made to achieve the required pavement configuration or <br /> depth of cut. Measure the cross slope of the milled surface by placing the level at the center <br /> location of a lane and perpendicular to the roadway centerline . Record all the measurements to <br /> the nearest 0 . 1 % on an approved form and submit to the Engineer for documentation . <br /> 1 . Tangent Sections : Measure the cross slope per lane at a minimum <br /> frequency of one measurement every 100 feet. Calculate the absolute deviation of cross slope at <br /> each measurement and then average the absolute deviation of ten consecutive cross slope <br /> measurements . The absolute deviation is the positive value of a deviation . When the average <br /> absolute deviation cross slope is consistently within the acceptance tolerance as shown in Table <br /> 327 - 1 and upon approval by the Engineer, the frequency of the cross slope measurements can be <br /> reduced to one measurement every 200 feet during milling operations . . <br /> 2 . Superelevated Sections : Measure the cross slope every 100 feet per lane <br /> within the length of full superelevation . Calculate the absolute deviation of each measurement <br /> and then average the absolute deviation of ten consecutive cross slope measurements . For every <br /> transition section, measure the cross slope at control points identified in the plans or, if not <br /> shown in the plans , at a control point at a location of 0 . 0 % cross slope . For curves where the <br /> length of the fully superelevated section is less than 250 feet, measure the cross slope at the <br /> beginning point, midpoint and ending point of the fully superelevated section, calculate the <br /> absolute deviation and average . When the number of measurements is less than ten and the <br /> ell length of full superelevation is greater than 250 feet, average the absolute deviation of all <br /> measurements . <br /> If the average absolute deviation of the cross slope measurements falls outside the <br /> acceptance tolerance shown in Table 327 - 1 , stop the milling operations and make adjustments <br /> until the problem is resolved to the satisfaction of the Engineer . If an individual cross slope <br /> deviation falls outside the acceptance tolerance as shown in Table 3274 , make corrections only <br /> in the deficient area to the satisfaction of the Engineer at no cost to the Department. For <br /> pavement with multiple cuts , the deficient areas not caused by the final cut may be left in place <br /> upon approval of the Engineer. All milling corrections shall be completed before placement of <br /> the asphalt course unless stated otherwise in the plans or as determined by the Engineer. <br /> The limits of deficient areas requiring correction may be verified and adjusted <br /> with more accurate measurement methods , including survey instruments , upon approval by the <br /> Engineer at no cost to the Department . Should the Contractor wish to have any corrections <br /> waived, submit a request to the Engineer for approval . The Engineer may waive the corrections <br /> at no reduction in payment if an engineering determination indicates that the deficiencies are <br /> sufficiently separated so as not to significantly affect the final cross slope or project grade . <br /> For intersections , tapers , crossovers , transitions at the beginning and end of the <br /> project, bridge approaches and similar areas , adjust the cross slope to match the actual site <br /> conditions , or as directed by the Engineer . <br /> -65 - <br /> FPID ( S) : 423186 - 1 - 58 - 01 <br /> ell <br /> ell e <br /> �. <br /> ell <br /> �. <br /> P <br /> Bk <br />
