How much lime should I use to stabilize clay soils to generate long-term strength gain?
A fact sheet on soil stabilization is available under Technical Information. There is an ASTM test method to approximate the amount of lime needed to stabilize soils, D 6276. (This procedure is also called the Eades and Grim test.) The standard can be purchased directly from ASTM, www.astm.org . However, to be confident that a stabilized soil can provide structural strength, more rigorous testing is required. The National Lime Association has proposed a testing protocol in a report entitled “Evaluation of Structural Properties of Lime Stabilized Soils and Aggregates, Volume 3: Mixture Design and Testing Protocol for Lime Stabilized Soils.” March 2000. This report is available under Technical Information.
