Basalt Fiber Geomats – Modern Material for Reinforcing the Motor Road Embankment Slopes

Abstract The article is devoted to the technology of carrying out works on reinforcing the embankment slopes with the optimal type of geosynthetic material - BV-I geomat made of basalt fibers and substantiating the location of the interlayer in the sloping section of the embankment. Existing geosynthetic materials used for slope reinforcement are analyzed and the type of the geomat selected for reinforcing the embankment slope is scientifically grounded. Classification of existing products has been developed and experimental studies have been conducted to determine the geomats properties for reinforcing the embankment slopes made of polymeric materials and basalt fibers. The advantages of reinforcing the embankment slopes with BV-I basalt fiber geomat are presented. It is possible to achieve the required level of highway reliability with their help and extend the service life of individual elements. By increasing the period between the subgrade and road pavement repairs, it is possible to gain a significant economic effect.
