Reinforcement of a road embankment during the construction of an access road at a gas condensate field

Stabilisation and strength enhancement of road pavement layers made of inert materials  

Use of the “TECHPOLYMER” volumetric geogrid — a three-dimensional synthetic geogrid consisting of polymer strips bonded together in a staggered pattern by ultrasonic welding. The material limits shear deformation and reinforces the soil, creating a single structural mass capable of withstanding heavy loads. 

A composite mat with geotextile coating on both sides — Hydromat 3D. — is used as a drainage layer. The use of Hydromat significantly reduces the moisture coefficient of road layers and eliminates frost heave. 

• Reduced consumption of granular material in the embankment base without reducing structural strength; 
• Uniform load distribution on the embankment base;
• Increased overall stability of the earth structure.
