Computerized Aided Modeling of Soil Mix Design to Predict Characteristics and Properties of Stabilized Road Base
Record Type: DOT

Considerable data exists for soils that were tested and documented, both for native properties and properties with pozzolan stabilization. While the data exists there currently is no database for the Nebraska Department of Roads to retrieve this data for predicting soil properties. The conventional method used to determine soil properties, such as maximum laboratory density and optimum moisture content, is tedious, labor intensive and time consuming. When soil stabilization is involved, more time and efforts are needed to determine maximum laboratory density, optimum moisture content and optimum pozzolan content. The objective of this project is to develop a computerized model to predict the soil properties of a given GI soil type using additives for soil stabilization. The model will be able to predict the maximum laboratory density and optimum moisture content of native soil. Additionally the model will determine an optimum pozzolan percentage of soil stabilization.
