Scope
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 improves 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@ etc. Specification requirements for these materials could be better determined on a local basis. 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.
