Abstract: To increase the repair time of highways and improve the efficiency of road construction, a method of plasticization of cement soils is recommended as one of the effective modification methods in the technology of strengthening soils for road pavement. The effect of a superplasticizer based on nitrogen-containing condensation polymers on the physico-mechanical and design characteristics of a light powdery loam reinforced with portlandcement at different contents has been studied. The positive effect of the superplasticizer and the level of increase in compressive strength, flexural tensile strength, frost resistance coefficients and elastic modulus of plasticized cement primers have been established. Depending on the content of portlandcement and the field of application of reinforced soils in the structures of road pavements, optimal superplasticizer contents have been established.

Keywords: cement soils, modification, plasticization, superplasticizer, road pavement, strength, frost resistance, elastic modulus.
