1.1 This test method covers the determination of the complex shear modulus and phase angle of asphalt binders when tested in dynamic (oscillatory) shear using parallel plate geometry. 1.2 This test method is intended for determining the linear viscoelastic properties of asphalt binders as required for specification testing and is not intended as a comprehensive procedure for the full characterization of the viscoelastic properties of asphalt binder. 1.3 This standard is appropriate for unaged asphalt binder, conditioned asphalt binder, and asphalt binder recovered from either asphalt mixtures or asphalt emulsions. To keep the language in this standard precise, the term “asphalt binder” is used to refer to the material being tested. 1.4 This procedure is limited to asphalt binders that contain particles with largest dimension less than 250 μm. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 Warning— Mercury has been designated by the United States Environmental Protection Agency (EPA) and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for details and EPA’s website— www.epa.gov/mercury/faq.htm—for additional information. Users should be aware that selling mercury, mercury-containing products, or both, into your state may be prohibited by state law. 1.7 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
选用国内外有代表性的几种沥青,按照AASHTO标准方法,用动态剪切流变仪及弯曲梁流变仪对沥青的高、低温性能进行了评价,并与常规评价沥青的方法进行了对比。试验结果表明,利用这两种流变仪评价沥青的使用性能与常规评价指标有很好的相关性。此外,两种流变仪测定的指标能够反映沥青结合料的流变性随荷载、时间、温度的变化而发生的变化,是一种更为合理的评价手段。同时,探讨了影响沥青高温车辙及低温开裂的主要因素。...
根据模量大小、弹性和粘性成分的变化,便可以指示出沥青的力学性能;根据不同的测试温度范围,也可以得到沥青在不同温度区(低温、中温、高温区)的力学性能;根据不同剪切频率的变化,可以看出车速和荷载对沥青性能的影响。SHRP性能指标中的车辙因子G*(sinδ)-1和疲劳因子G*sinδ的测定使用的动态剪切流变仪(DSR)即为旋转流变仪。...
