Research and Evaluation of Lithuanian Asphalt Concrete Road Pavements Reinforced by Geosynthetics
 
The paper focuses on the main functions of geosynthetics in asphalt concrete structures; it also offers results of the research into asphalt concrete pavements reinforced by geosynthetics. The present investigation also includes evaluation of the impact of geosynthetics. The analysis has helped identify the reological parameters whose values are related directly to geosynthetics. The regressive equations help calculate the depth of ruts, if the elasticity modulus and the viscosity of asphalt concrete are given. The statistical analysis supports the validity of the equations. The conclusions at the end of the paper refer to the reliability of geosynthetics used in asphalt concrete pavements.
 
Keywords: geosynthetics, reinforcement, rutting, the modulus of elasticity, viscosity.
