The use of phosphates for stabilizing soil to be used for road building is a new development. Lyons (1) apparently was one of the first to have appreciated the possibility. He reports that compacted plastic clay soils containing about 2 per cent phosphoric acid have greatly improved resistance to water and weathering, but he gives no explanation of the mechanism of soil-phosphoric acid stabilization. In agriculture it has been known for some time that phosphates are fixed in soil (2). It is also known that sodium phosphates may be used to disperse soils in water for particle size analysis (3). This paper presents a tentative explanation, based on limited experimental evidence, of the mechanism of soil stabilization with phosphates.
