The Soil Exploration and Mapping Cooperative Project in Illinois


The Soil Exploration and Mapping Project of the Illinois Cooperative High-way Research Program is a joint venture of the Illinois Division of Highways, the U. S. Department of Commerce, Bureau of Public Roads, and the University of Illinois Engineering Experiment Station. Work, at present, consists of the preparation of soils maps for use by the Illinois Division of Highways as an aid in planning the relocation and improvement of existing roads and the location of new highways. Parallel to mapping, extensive soil sampling and testing is also performed to determine the engineering properties of the soil types mapped. In addition to the above, research is being conducted in relation to soil properties and the influence of subgrade soils on highway pavement performance. The ultimate goal of the project is the publication of a soils manual for the State of Illinois.
