334-1.2.2 Asphalt Work Category 2: Includes the construction of new asphalt turn lanes, paved shoulders and other non -mainline pavement locations. 334-1.2.3 Asphalt Work Category 3: Includes the construction of new mainline asphalt pavement lanes, milling and resurfacing. 334-1.3 Mix Types: Use the appropriate asphalt mix as shown in Table 334-1. Table 334-1 Asphalt Mix Types Asphalt Work Category Mix Types Traffic Level ESALs (millions) 1 Type SP -9.5 A <0.3 Structural Mixes: Types SP -9.5 or SP - 2 12.5 Friction Mixes: Types FC -9.5 or FC- B 0.3 to <3 12.5 Structural Mixes: Types SP -9.5 or SP - 3 12.5 C >3 Friction Mixes: Types FC -9.5 or FC - 12.5 A Type SP or FC mix one traffic level higher than the traffic level specified in the Contract may be substituted, at no additional cost (i.e. Traffic Level B may be substituted for Traffic Level A, etc.). Traffic levels are as defined in Section 334 of the Florida Department of Transportation's (FDOT's) Specifications. 334-1.4 Gradation Classification: The Superpave mixes are classified as fine and are defined in 334-3.2.2. The equivalent AASHTO nominal maximum aggregate size Superpave mixes are as follows: TypeSP -9.5, FC-9.5............................................................. 9.5 mm Type SP -12.5, FC -12.5 ....................................................... 12.5 mm 334-1.5 Thickness: The total pavement thickness of the asphalt pavement will be based on a specified spread rate or plan thickness as shown in the Contract Documents. Before paving, propose a spread rate or thickness for each individual layer meeting the requirements of this specification, which when combined with other layers (as applicable) will equal the plan spread rate or thickness. When the total pavement thickness is specified as plan thickness, the plan thickness and individual layer thickness will be converted to spread rate using the following equation: Spread rate (lbs/yd2) = t x Gn,m x 43.3 where: t = Thickness (in.) (Plan thickness or individual layer thickness) G„m = Maximum specific gravity from the mix design For target purposes only, spread rate calculations shall be rounded to the nearest whole number. 334-1.5.1 Layer Thicknesses: Unless otherwise called for in the Contract Documents, the allowable layer thicknesses for asphalt mixtures are as follows: Type SP -9.5, FC -9.5 ............................................3/4 to 1-1/2 inches 01025-27 Technical Specifications R\Public Works\ENGINEERING DIVISION PROJECTS\1503-43rd Ave Swk_Airport Dr to 41st St\1-Admin\13ids\Bid Documents\Master Contract Documents\Technical Specifications.doc
