ASTM D3551-17

4.1 This practice standardizes the preparation of soil-lime mixtures for laboratory testing by engineers and researchers interested in determining properties of soil when stabilized with lime. In this method, the mellowing period is mentioned, but no specific recommendations are made because the mellowing period to be used in testing depends upon each specific use.

1.1 This practice covers the laboratory preparation of soil-lime mixtures for use in determining the effects of lime on soil properties (plasticity, strength, moisture-density relations, etc.) and the design of mixtures for construction.

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 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.

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 practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgement. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved the ASTM consensus process.

1.6 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.
