Today a major problem in the State of Iowa is the development of substitute materials which can be used in place of the rapidly diminishing supplies of readily available gravel and rock surfacing materials for roads and streets. The materials now available are not evenly distributed throughout the state, and the rate at which they are being used indicates that it will soon be necessary to turn to materials which are not now considered suitable. One such material is fine sand, commonly discarded by gravel plants as waste. Fine sand is readily available in almost every section of the state. It forms a portion of the flood plain deposits of many of the major rivers and streams and is found in a variety of occurrences related to the glacial drift sheets of the -state. The Iowa State Highway Commission has inaugurated a research program to find ways of utilizing fine sands as highway surfacing materials. The portion of this problem dealing with the determination of fundamental properties of the sands was assigned to the Iowa Engineering Experiment Station, Iowa State College. This report presents the results of the Station's study of five samples of fine sand.
