Standard Test Method for Using pH to Estimate the Soil-Lime Proportion Requirement for Soil Stabilization
1.1 This test method covers a means for estimating the soil-lime proportion requirement for stabilization of a soil. The optimum soil-lime proportion for soil stabilization is determined by tests of specific characteristics of stabilized soil such as unconfined compressive strength or plasticity index.
1.2 This test method is used to determine the lowest percentage of lime that results in a soil-lime pH of 12.4.
1.3 Lime is not an effective stabilizing agent for all soils. Some soil components such as sulfates, phosphates, organics, etc. can adversely affect soil-lime reactions.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 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.
