The native normative documents don’t give the possibility to determine the effect of geosyn-thetic materials on characteristics of strength of road pavement structure, particularly, on overall modulus of elasticity of road pavement structure.
To determine the effect of geosynthetics on overall modulus of elasticity three research objects were ar-ranged. Measuring of overall modulus of elasticity of road pavement structure at these objects was done by handy deflectometer with drop weight.
On the base of theoretical dependences and statistical analysis of measuring results it was determined the meaning of reinforcement ratio of road pavement grained layers with application of different types of geo-synthetics.
