Abstract

It is widely recognized in Iowa that there are not enough economically available supplies of sand, gravel, and rock in the state to meet the road building needs of the present and future. While certain counties have been favored more than others with aggregate deposits, this statement applies to the entire state, if a long-range view point is taken. Many other sections of the United States, as well as many foreign countries, are faced with a similar shortage. A solution to this problem is to learn how to treat or process readily available materials to increase their all-weather stability for road construction. In Iowa the abundance and wide distribution of loess and glacial till materials makes them the logical ones with which to start working. For this purpose, a project entitled An Investigation of Loess and Glacial Till Materials in Iowa was recently (September, 1950) established at the Engineering Experiment Station of Iowa State College. The project is being carried on under contract with the Iowa State Highway Commission and under the sponsorship of the Iowa Highway Research Board. It is supported by funds supplied by the Commission and the U. S. Bureau of Public Roads.
