MD <br />0 <br />SECTION 02305 <br />ASMIIALTPAVI HENT <br />1. DESCIII17ION <br />A. Under this item, tate Contractor shall construct an asphalt concrete wearing <br />'d surface for pavement upon a previously prepared base course conforming to <br />the lines, ,grades, and typical section show[[ on the drawings. <br />2. LIMITATIONSOF LAYING OPE RATION <br />A. Bituminous materials shall be applied only when (lie temperature of [lie air in <br />[lie shade is above fifty degrees Fahrenheit (50o F.). Any bituminous mixture <br />caught in transit by a sudden rain may be laid at the Contractor's risk. <br />However, no work shall be started if local conditions indicate that rain is <br />imminent, and under no circumstances shall [1[e mixture be laid while rain is <br />failing, or wizen there is water on the base. When wind is blowing to such an <br />extent [fiat sand, dust, etc. are being deposited on the surface being paved to <br />the extent that the bond between layers will be diminished, the bituminous <br />niaterials shall not be spread on [tie surface. <br />13. The Contractor shall supply thernonieters as required by [he Engineer for <br />delertmluing the temperature of all bituminous materials as they are applied. <br />!laying of bituminous materials will not be permitted unless the material has <br />obtained [lie proper temperature and temperature denernination at the job <br />site has been made. <br />3. 'TACK COAT <br />A Where a tact; coal is required (as determined by lite Engineer) prior to <br />application of the asphaltic concrete wearing surface or against an existing <br />asphalt surface, an Emulsified Asphalt, Grade RS 2 shall be used. The tack <br />coat shall be applied uniformly welt a pressure distributor or by hand at (lie <br />rate of 0.05 gallons per square yard and at a temperature between 1000 F. <br />and 1500 F. The tack coat surface shall be kept free front traffic until [lie <br />subsequent layer of asphaltic concrete has been laid. Excessive application of <br />tack coat on lite existing asphalt surfaces will be eliminated by the Contractor <br />prior to paving the asphalt concrete. <br />4. ASPI IALTIC CONCRUE WEARINGSUIMACE <br />A. The wearing surface for [lie on site parking lots and driveways shall be Florida <br />D.O.T. Type S -I asphaltic concrete conforming to the requirements of <br />Section 331 of [lie 1986 Edition of [lie Florida D.O.T. Specifications. 'Fite <br />material shall be laid uniformly so [fiat it will result in a compacted Iltickness <br />of one inch. The aspliallic concrete_ shall be laid down at a leniperature of <br />between 230OF and 310 OF, The temperature of the asphalt concrete <br />delivered to the job shall be constant and wide fluctuations of lemlperature <br />during (lie day will not be permitted. Asphallic conerele whose temperature is <br />less than 210OF when delivered to file job site may result in innuediale <br />rejection front application by the Engineer. All [material rejected by the <br />Engineer shall be replaced with specified material by the Contractor at nn <br />additional cost [v the Owner. <br />B. `!'lie asphallic concrete slialI be applied by an approved tylle of self propelled <br />paver, such as a Barber Green, callable of inking a cominuous 1() rt. wide <br />02305-1 <br />
