Standard Practice for Preparation of Compacted Slab Asphalt Mix Samples Using a Segmented Rolling Compactor 使用分段式压实机制备压实板沥青混合料样品的标准实施规程
发布日期: 2023-11-01
1.1 本规程涵盖使用自动实验室碾压机(RC)制造沥青混合料板。压实试样适用于体积和物理性能测试。这种做法不应用于验收或拒绝材料或用于采购目的。 1.2 单位-- 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 本标准的文本引用了提供解释性材料的注释和脚注。这些注释和脚注(不包括表和图中的注释和脚注)不应被视为本标准的要求。 1.4 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5.1 用滚动压实机压实的沥青板可用于获得进一步测试的试样,包括以下测试方法的体积比重 D1188/D1188米 , D2726/D2726米 和 D6752/D6752M ,符合试验方法的疲劳性能特征 D7460 和 D8237 或AASHTO T 321,以及遵循AASHTO T 324的汉堡车轮轨道测试。 5.2 也可以获得进行其他标准测试的样品,只要其体积包含在板坯的体积内。 注1: 本标准产生的结果的质量取决于执行程序的人员的能力以及所用设备的能力、校准和维护。 符合规范标准的机构 D3666 通常被认为能够胜任和客观的测试、取样、检查等。提醒本规范的用户遵守规范 D3666 单独使用并不能完全确保可靠的结果。可靠的结果取决于许多因素;遵循规范的建议 D3666 或者提供评估和控制这些因素中的一些因素的方法的一些类似的可接受的指南。
1.1 This practice covers the fabrication of slabs of asphalt mix using an automated laboratory rolling compactor (RC). Compacted specimens are suitable for volumetric and physical property testing. This practice should not be used for acceptance or rejection of a material or for purchasing purposes. 1.2 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 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. 1.5 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. ====== Significance And Use ====== 5.1 Asphalt slabs compacted with the rolling compactor can be used to obtain specimens for further testing, including bulk specific gravity following Test Methods D1188/D1188M , D2726/D2726M , and D6752/D6752M , fatigue performance characteristics following Test Methods D7460 and D8237 or AASHTO T 321, and Hamburg wheel-track testing following AASHTO T 324. 5.2 Specimens to perform other standard tests could also be obtained, as long as their volume is contained within the volume of a slab. Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this practice are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline that provides a means of evaluating and controlling some of those factors.
