Traffic levels are as defined in Section 334 of the Florida Department of <br /> Transportation's (FDOT's) Specifications. <br /> 334-1.4 Gradation Classification:The Superpave mixes are classified as fine and are <br /> defined in 334-3.2.2. The equivalent AASHTO nominal maximum aggregate size <br /> Superpave mixes are as follows: <br /> Type SP-9.5, FC-9.5 9.5 mm <br /> Type SP-12.5, FC-12.5 12.5 mm <br /> 334-1.5 Thickness: The total pavement thickness of the asphalt pavement will be <br /> based on a specified spread rate or plan thickness as shown in the Contract Documents. <br /> Before paving, propose a spread rate or thickness for each individual layer meeting the <br /> requirements of this specification,which when combined with other layers(as applicable)will <br /> equal the plan spread rate or thickness. When the total pavement thickness is specified as ff <br /> plan thickness, the plan thickness and individual layer thickness will be converted to spread 1 <br /> 1' <br /> rate using the following equation: <br /> i <br /> Spread rate (lbs/yd2) = t x Gmm x 43.3 <br /> II <br /> where: t = Thickness (in.) (Plan thickness or individual layer <br /> thickness) j <br /> Gmm = Maximum specific gravity from the mix design <br /> For target purposes only, spread rate calculations shall be rounded to the <br /> nearest whole number. <br /> 334-1.5.1 Layer Thicknesses: Unless otherwise called for in the Contract <br /> Documents, the allowable layer thicknesses for asphalt mixtures are as follows: j <br /> Type SP-9.5, FC-9.5 3/4 to 1-1/2 inches <br /> Type SP-12.5, FC-12.5 1-1/2 to 2-1/2 inches <br /> 334-1.5.2 Additional Requirements: The following requirements also apply to <br /> asphalt mixtures: H <br /> I <br /> 01025-35 Technical Specifications <br /> F:1Public Works\ENGINEERING DIVISION PROJECTS\1123 43rd Ave Sidewalk Improvements 26th St.to Airport Dr West\Admim\bid <br /> documents\Master Contract Documents\Technical Specifications.doc <br />
