  • Abstract:
    One of the universal truths is that road construction is dependent on the materials at hand. At one time or another, almost every material common to an area has been tried by road builders. Roads of sand and clay are an example. Sand-clay road construction was one of the common methods of providing a stable road surface in the early 20th century. The idea was that adding clay to sandy roads gave them stability; adding sand to clay surfaces prevented them from rutting and becoming sticky in wet weather. Historian Albert Rose explained the tricky part of construction was getting the proper proportions of sand and clay so that "the clay acted as a binder while the sand particles were permitted to bear upon each other and interlock so as to resist displacement by traffic." The origins of sand-clay roads can be traced to ancient times. In the United States, information about sand-clay roads appeared in the earliest literature on building roads.
