(2/04) <br /> Sec. 10-1, Construction Details <br /> Std. Spec. Sec. 39 <br /> Special <br /> Page 2of3 <br /> The sixth paragraph in Section 39-6.01, "General Requirements," of the Standard <br /> Specifications, shall be amended by deleting the second footnote, which reads, "At the <br /> option of the Contractor, one layer 75 mm {0.25-foot} thick may be placed." <br /> The tenth paragraph of Section 39-6.03, "Compacting," of the Standard <br /> Specifications, allowing the use of"alternative compacting equipment" shall be deleted. <br /> Unless otherwise shown on the plans, asphalt paver equipment used to place <br /> asphalt concrete shall be equipped with full automatic screed and grade sensing <br /> controls which shall control the longitudinal grade and transverse slope of the screed. <br /> The controls shall be actuated by grade and slope references. Corrections on account <br /> of deviations from the references shall be automatic. Guides and references required to <br /> control the longitudinal grade and transverse slopes shall be furnished and installed by <br /> the Contractor. <br /> Should the Contractor elect to use a ski device for longitudinal control, the <br /> minimum length of the device shall be 30 feet. The device shall be a rigid unit mounted <br /> on multiple supports. Each support shall act independently of others and the finished <br /> grade shall not be affected by the action of a single support. Alternative longitudinal <br /> grade control equipment with grade averaging capability may be used with approval of <br /> the Engineer. <br /> When asphalt concrete gutters are designated on the plans, a stringline or wire <br /> grade reference shall be required to control longitudinal grade of the gutter. The gutter <br /> shall be water tested before acceptance. The maximum deviation from a true grade <br /> shall not result in ponding water for depth exceeding 0.04 foot. <br /> Surfacing operations shall be conducted in such a manner that, at the end of <br /> each day's work, the distance between the ends of adjacent surfaced lanes shall not be <br /> greater than can be completed in the following day of normal surfacing operations. <br /> Portable delineators in conformance with Section 12-3.04, "Portable Delineators," <br /> of the Standard Specifications shall be furnished and placed at a maximum spacing of <br /> 300 feet on tangents and 100 feet on curves along any edge of new surfacing which has <br /> a drop off of more than 0.10 foot. Delineators shall be staggered when required on both <br /> sides of traffic. <br /> (SPECS.CDSISSS39-A-P2) <br /> RTERRACE-Sss39-a-p2-RC <br />
