1.1 本规范适用于用于土壤稳定的生石灰和熟石灰，高钙、白云石或镁质石灰（见 注2 ). 注1: 生石灰和熟石灰作用于粘土，并可使此类土壤适用于公路建设和其他承重应用。在大多数情况下，石灰会使细碎的粘土颗粒凝聚成较粗的颗粒，从而提高承载性能，随后石灰处理的土壤会通过化学反应硬化。 注2: 没有试图提出对副产品石灰、商业石灰浆等的要求。这些材料的规格要求可以在当地基础上更好地确定。 1.2 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.3 本标准并不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。 1.4 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。

1.1 This specification pertains to quicklime and hydrated lime, either high calcium, dolomitic, or magnesian lime, for use in stabilization of soils (see Note 2 ). Note 1: Quicklime and hydrated lime act upon clay soils and may render such soils suitable for highway construction and for other load-bearing applications. In most cases, lime causes finely divided clay particles to agglomerate into coarser particles which improve load-bearing properties and subsequently the lime-treated soil hardens by chemical reaction. Note 2: No attempt is made to present requirements for by-product lime, commercial lime slurry, and so forth. Specification requirements for these materials could be better determined on a local basis. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. 1.4 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.
