334-3.2.2.1 Mixture Gradation Classification: Plot the combined <br /> mixture gradation on an FHWA 0.45 Power Gradation Chart. Include the Control Points from <br /> AASHTO M323-12, Table-3, as well as the Primary Control Sieve (PCS) Control Point from <br /> AASHTO M323-12,Table 4. Fine mixes are defined as having a gradation that passes above <br /> or through the primary control sieve control point. <br /> 334-3.2.3 Gyratory Compaction: Compact the design mixture in accordance <br /> with AASHTO T312-12,with the following exceptions: use the number of gyrations at Ndesign <br /> as designed in Table 334-3. <br /> Table 334-3 <br /> Gyratory Com action Requirements <br /> Traffic Level Ndes; n Number of Gyrations <br /> A 50 <br /> B 65 <br /> C 75 <br /> 334-3.2.4 Design Criteria: Meet the requirements for nominal maximum <br /> aggregate size as defined in AASHTO M323-12, as well as for relative density, VMA, VFA, <br /> and dust-to-binder ratio as specified in AASHTO M323-12, Table 6. Ninitial and Nmaximum <br /> requirements are not applicable. <br /> 334-3.2.5 Moisture Susceptibility: Test 4 inch specimens in accordance with <br /> FDOT Test Method FM 1-T 283. Provide a mixture having a retained tensile strength ratio of <br /> at least 0.80 and a minimum tensile strength (unconditioned) of 100 pounds per square inch. <br /> If necessary, add a liquid anti-stripping agent from the FDOT's APL or hydrated lime in order <br /> to meet these criteria. <br /> In lieu of moisture susceptibility testing, add a liquid anti-stripping agent <br /> from the FDOT's APL. Add 0.5% liquid anti-stripping agent by weight of asphalt binder. <br /> 334-3.2.6 Additional Information: In addition to the requirements listed above, <br /> provide the following information on each mix design: <br /> 1. The design traffic level and the design number of gyrations (Ndesign). <br /> 2. The source and description of the materials to be used. <br /> 3. The FDOT source number and the FDOT product code of the <br /> aggregate components furnished from an FDOT approved source (if required). <br /> 4. The gradation and proportions of the raw materials as intended to be <br /> combined in the paving mixture. The gradation of the component materials shall be <br /> representative of the material at the time of use. Compensate for any change in aggregate <br /> gradation caused by handling and processing as necessary. <br /> 5.A single percentage of the combined mineral aggregate passing each <br /> specified sieve. Degradation of the aggregate due to processing(particularly material passing <br /> the No. 200 sieve) should be accounted for and identified. <br /> 6.The bulk specific gravity(Gsb)value for each individual aggregate and <br /> RAP component. <br /> 7.A single percentage of asphalt binder by weight of total mix intended to <br /> be incorporated in the completed mixture, shown to the nearest 0.1%. <br /> 8. A target temperature for the mixture at the plant(mixing temperature) <br /> and a target temperature for the mixture at the.roadway (compaction temperature).
