The construction of the bypass of the town Drezdenko stage I (in the course of regional roads no. 158–160)
The plan was to perform construction works consisting in the soil and embankment stabilisation with geosynthetic inserts. Highly durable products with low creep were recommended for the long-term stabilisation. The strengthening structure was made of the woven geotextile fabric with the strength of 100/50kN/m, a material made of synthetic polyester fibres, combined into flat long weaves, interleaved, with a uniform surface.
The geosynthetic was laid with a controlled uniform tension lengthwise, and then
covered with a layer of all-in aggregate 0,3m thick. Every laid layer of the woven geotextile fabric was compacted, and then the geosynthetic was anchored on the edges of a
half-mattress with a hem of 2,5m. After the compaction, at the face of the layer (formwork), another layer of the all-in aggregate, 0.20m thick and 1,00m long from the edge of the bluff was laid and compacted. After the compaction, the material was anchored by wrapping the strips of the geosynthetic material, 2.50m high. Another action was laying the 0,2m thick all-in aggregate on the remaining area of the layer made and compacting it.
The woven geotextile fabric AT tex PES 100/50 under a steady, long-term load retains its high strength, is ideal for the reinforcement of the embankment bases. Due to the ability of transmit high tensile forces at a very low elongation, the woven geotextile fabrics are most often used as a strengthening material. The PES woven geotextile fabrics improve the distribution of loads, reduce settlement and prevent ruts.
