Polymer modified asphalt cement for use in pavement construction 1 Scope This standard specifies the requirements for classification, technical conditions, storage and transportation of polymer modified asphalt cement for use in pavement construction. This standard is applicable to polymer modified asphalt cement made of styrene-butadiene-styrene block copolymer (SBS), styrene butadiene rubber (SBR), ethylene-vinyl acetate copolymer (EVA) and polyethylene (PE) as modified admixture materials. For the purpose of other polymer modified asphalt cements meeting the series indexes of this standard, this standard can serve as a reference. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments to (excluding any corrigendum), or Modification of, any of these publications do not apply. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the latest editions of the standards indicated below. For undated references the latest edition of the normative document applies.

For the purpose of this standard, it refers to raw rubber synthesized by emulsion method and not vulcanized 3.3 ethylene-vinyl acetate copolymer resin made by copolymerization of ethylene and vinyl acetate Such commonly used products are ones produced by high-pressure bulk polymerization. 3.4 polyethylene Ethylene monomer is homopolymerized under different production conditions. Low density polyethylene polymerized at high pressure is commonly used in this standard.
