    Technology for reinforcing the base of the subgrade at rail joints using geotextiles

    This article presents promising and widely used in transport construction methods of earth bed reinforcement with the use of geotextile as a reinforcing and separating layer. It was suggested to lay down geotextile coverings manually in the zones of rail joints of an equalizing span of a continuous-flow track by 6-10 sleepers in each side of the joint, in all, 12-20 sleepers where high-speed and high-speed passenger traffic is expected. Basic technical requirements and restrictions on geometric dimensions for geotextile when reinforcing the main track bed are given. The technology of manual laying of reinforcing geotextiles when a small section of the railway track needs reinforcement during routine maintenance and repair of the railway track is given. The sequence of basic manual laying of geotextile coverings in the technological "windows" is described. Experimentally conducted work on the device coatings of geotextile manually in the areas of rail joints equalizing span of permanent way for 6 sleepers on each side of the junction in the railway sections of the Tashkent railway station (PCH-2). A design for reinforcement of the main ground in the areas of rail joints has been proposed. The basic requirements to quality control of construction works in structures with the use of a layer of geotextile materials are given.
