1.1本试验方法包括测定从在建项目或泥磨机或两者中取样的土壤-石灰混合物的石灰含量。 1.2在CaCo含量高度可变的土壤中 3. （如caliche），可能难以获得代表性样本。 1.3以公制单位表示的数值应视为标准。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法可用于测定未固化土壤石灰混合物中的石灰含量。 5.1.1公路部门等机构需要土壤石灰混合物中的石灰含量，这些机构必须确定土壤石灰中的石灰含量，以向承包商付款，检查是否符合规范，或检查质量控制措施的有效性。 5.1.2石灰含量也是土壤-石灰混合物生产商需要的，他们必须为生产控制目的确定石灰含量。 笔记 1-尽管本试验方法中包含精度和偏差声明: 该测试方法的精度取决于执行该测试的人员的能力以及所用设备和设施的适用性。符合实践D 3740标准的机构 通常认为能够胜任和客观测试。本试验方法的使用者应注意遵守实施规程D 3740 本身不能确保可靠的测试。可靠的测试取决于几个因素；实践D 3740 提供了评估其中一些因素的方法。

1.1 This test method covers the determination of the lime content of soil-lime mixtures sampled from a project under construction or at the pug-mill, or both. 1.2 In soils with highly variable amounts of CaCo 3 (such as caliche), it may be difficult to obtain a representative sample. 1.3 The values stated in metric units are to be regarded as the standard. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method can be used to determine the lime content of uncured soil-lime mixtures. 5.1.1 Lime content in soil-lime mixes is needed by agencies such as highway departments, that have to determine lime content in soil-lime for payments to contractors, to check compliance with specifications, or to check the efficacy of quality control measures. 5.1.2 Lime content is also needed by producers of soil-lime mixtures who have to determine lime content for production control purposes. Note 1—Notwithstanding the statements on precision and bias contained in this test method: The precision of this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D 3740 are generally considered capable of competent and objective testing. Users of this test method are cautioned that compliance with Practice D 3740 does not in itself ensure reliable testing. Reliable testing depends on several factors; Practice D 3740 provides means of evaluating some of those factors.
