Abstract. Application of a phosphite for construction of highways is expedient for economic and ecological reasons. Most effective use of a semi-hydrate form of a phosphite for construction of local roads. One of limiting factors of wide use of a phosphite in road construction is lack of due regulatory base.

By production of extraction phosphoric acid on the Balakovo branch JSC Apatit the method of vitriolic decomposition of phosphorus-containing raw materials by sulfuric acid a lot of phosphoric acid with the subsequent division of the received phosphoric acid (a liquid phase) and educated crystalline hydrate of sulfate of calcium in a floor – or a digidratny form (a firm phase) on a vacuum filtration is used. Digidratny and semi-hydrate process of vitriolic receiving phosphoric acid along with two-phasic processes are the most economically effective processes.
