Determination of the percentage of lime in the strengthening of clay soils using pH

Abstract

The construction of roads is associated with a large resource consumption, including scarce high-strength stone materials. Transportation of these materials over long distances is economically unprofitable, especially for low-cost technical categories. Today, the strengthening of local soils with binders is an important way to be an effective and cost-effective method of construction, reconstruction and overhaul of highways. The most promising mineral binder for strengthening clay soils is lime. The paper presents the results of laboratory tests to determine the percentage of lime, depending on the value of pH.
