| Popis: | This work is devoted to the study of applicability of the Underbold stabilizer for clay soils in the Vologda region, Russia. The influence of the stabilizer on maintaining the ultimate compressive strength of reinforced soils is shown. It depends on the content of clay particles (soil type) and can reach 30% if the appropriate technology (recommended by the manufacturer) is used. The use of the Underbold stabilizer according to our technology (treatment with a stabilizer - drying - reinforcing with cement) provides an increase in the strength of the reinforced soil after water saturation up to 2 or more times in comparison with samples without a stabilizer. It is shown that when designing a pavement using local clay soils reinforced by the Underbold stabilizer, it is necessary to make a water-insulating layer, and the necessary drainage system to improve the performance of the structural layer. It is noted that this stabilizer does not reduce the phenomenon of frost heaving. |
