Design features of repair of highways of the Volga-Akhtuba floodplain

The design features of the repair of regional highways located on the territory of the Volga-Akhtuba floodplain are due to significant wear and insufficient thickness of road coverings, high groundwater levels and flooding of the roadbed during spring floods. When repairing road clothes, the wear of their base and the reduced strength of the working layer of embankments due to increased soil moisture should be taken into account. It is rational to restore the strength of structures by recycling them. As a result of the intensive discharge of water from the Volga hydroelectric power station, ero-sion of embankment slopes is observed, due to the longitudinal flow of the water flow along the slope and sole, as well as the force action of waves and groundwater when aquifers exit onto the slope. The operation of roads in conditions of flooding by flood waters requires strengthening the slopes of em-bankments. Reducing the humidity of the working layer of the embankment is effective by widening and strengthening slopes in areas with high groundwater levels, as well as the installation of capillary-breaking layers or increasing the height of the embankment
