Laboratory Evaluation of Soil-Lime Mixtures: 1961-1962 Progress Report

A limited supply of high quality base aggregates in several parts of Minnesota has resulted in a search for a means of improving the physical and strength characteristics of locally available soils and poor quality granular materials. Other states faced with a similar problem have attempted to use soil stabilization as a solution. Common stabilization agents include cement, bituminous materials, sodium and calcium chloride, and sulfite liquor. More recently, several southern states have successfully used lime for stabilization of roadbed materials.

The purpose of this study is to determine the effect of hydrated lime on the physical and strength properties of typical Minnesota soils and aggregates. This first progress report presents the findings of tests conducted during 1961 using hydrated lime and five secondary chemical additives with five fine grained soils
