Virgin Material Mixtures Sample Clauses

Virgin Material Mixtures. Replace the first paragraph in Section 409.2(e)1 with the following: Size, uniformly grade, and combine aggregate fractions, bituminous material, and either WMA technology additive(s), modifiers or no special additive (s) or modifier (s), if mixture temperature, workability, and compactability is achieved solely through plant mechanical modification to produce foamed asphalt in proportions to produce a JMF that conforms to the material, gradation, and volumetric Superpave Asphalt Mixture Design requirements as specified in Bulletin 27, Chapter 2A, for the specified nominal maximum aggregate size and design ESALs except as procedurally modified by the WMA Technology Technical Representative or manufacturer to address laboratory procedures when preparing, compacting, and testing WMA mixtures and to achieve a uniform blend. Develop a hot mix asphalt (HMA) JMF according to Section 409.2 and incorporate the WMA technology additive, modifier, or process into that JMF during production. Do not develop a volumetric WMA JMF based on incorporating the WMA technology additive, modifier or process during the volumetric asphalt mixture design process. For all WMA mixture JMFs, perform moisture sensitivity analysis on laboratory mixed and laboratory compacted specimens that include the WMA Technology additive, modifier, or process as required in Bulletin 27, Chapter 2A for HMA using the same mixing, compaction, and conditioning criteria used during the development of the volumetric asphalt mixture design for the HMA JMF and ensure the WMA Technology additive modifier, or process is not detrimental to the moisture resistance of the mixture.
