• <br />7 <br />SECTION 2] - ASPHALT PAVEMEL! <br />1. DESCRTPTION a <br />A. Under this item, the Contractor shall construct an asphalt concrete <br />wearing surface for pavement upon a previously prepared base course <br />conforming to the lines, grades, and typical section shown an the <br />drawinns. <br />2. LIMITATIONS OF LAYING OPERATION <br />A. Bituminous materials shall be applied only when the temperature of the air <br />in the shade is above fifty degrees Fahrenheit (500 F.). Any bituminous <br />mixture caught in transit by a sudden rain may be laid at the <br />Contractor's risk. However, no work shall be started if local <br />conditions indicate that rain is imminent, and under no circumstances <br />shall the mixture be laid while rain is falling, or when there is water on <br />the base. When wind is blowing to such an extent that sand, dust, etc. are <br />being deposited on the surface being paved to the extent that the bond <br />l between layers will be diminished, the bituminous materials shall not be <br />spread on the surface. <br />B. The Contractor shall supply thermometers as required by the Engineer <br />for determining the temperature of all bituminous materials as they are <br />applied. Laying of bituminous materials will not be permitted unless the <br />material has obtained the proper temperature and temperature <br />determination at the job site has been made. <br />3. TACK COAT <br />A. Where a tack coat is required (as determined by the Engineer) prior <br />to application of the asphaltic concrete wearing surface or against an <br />existing asphalt surface, an Emulsified Asphalt, Grade RS 2 shall be <br />used. The tack coat shall be applied uniformly with a pressure <br />distributor or by hand at the rate of 0.05 gallons per square yard and at <br />a temperature between 100 F. and 1501 F. The rack coat surface shall <br />be kept free from traffic until the subsequent layer of asphaltic concrete <br />has been laid. Excessive application of tack coat on the existing asphalt <br />surfaces will be eliminated by the Contractor prior to paving the asphalt <br />concrete. <br />4. ASPHALTIC CONCRETE WEARING SURFACE <br />A. The wearing surface for the on site parking lots and driveways shall be <br />Florida D.O.T. Type FC -2 asphaltic concrete conforming to the <br />requirements of Section 331 of the 1991 Edition of the Florida D.O.T. <br />Specifications. The material shall be laid uniformly so that it will result <br />in a compacted thickness of one and one-half inch. The asphaltic concrete <br />shall be laid down at a temperature of between 230 F and 310 F. <br />The temperature of the asphalt concrete delivered to the job shall be <br />constant and wide fluctuations of temperature during the day will <br />
