(Test Method)Standard Test Method for Lime Content of Uncured Soil-Lime Mixtures
Standard Test Method for Lime Content of Uncured Soil-Lime Mixtures
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.
SCOPE
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.
