Title of the articleImproving the quality of soil stabilization by introducing hydrophobic additives
Abstract.This work is devoted to solving the urgent problems of the Republic of Tatarstan for connecting rural areas of paved roads and diversification of road-building materials from local soils. Based on the literature review identified key weaknesses reinforced cement local soils. The authors propose a method of improving the quality of local clay soils reinforced by the introduction of water repellent. The aim of the work was to study the physical and mechanical properties of the hardened cement local soil with the addition of liquid silicone GFS-1. According to the research determined the effect of liquid silicone GFS-1 on the physical and mechanical properties of local fortified clay soils. The test results showed that the introduction of reinforced soil repellent GFS-1 promotes growth of the compressive strength and tensile bending, increase water resistance, cold resistance, and therefore durability. Sustainable growth of defined physical-mechanical characteristics of the resulting material provides a broad range of applications in road construction. Technical and economic calculations show that the use of fortified soil instead of equally imported stone materials reduces construction costs by 20-60 %. In addition to the marked economic efficiency pavement with structural layers of the local fortified materials provide extended coverage preserving smoothness and help to improve the water-heat regime roadbed.
Keywords.Soil reinforcement, repellent, liquid silicone, compressive strength, tensile strength in bending and frost hardened ground.
