Panasyuk Y. Improvement of road construction technology of soil treatment with cement

Experience of application of technology of soil treatment at road pavements construction has been analyzed. Influence of additives of polypropylene fiber and latex "Butonal NS 198" at soil treatment with cement on technological and physico-mechanical properties has been theoretically substantiated and experimentally proved. Design characteristics of soil treated with cement, polypropylene fiber and latex "Butonal NS 198" and laying of road pavement layers based on it have been determined. Influence of additives different by origin in the composition of soil treated with cement on long-term frost resistance has been studied. Research results have been implemented in road organization at the construction of base course of airport runway and recommendations on the technology of soil treatment with cement and polypropylene fiber, and laying of pavement using it have been developed.
