EXPERIMENTAL RESEARCH ON THE DEVELOPMENT OF RUTTING IN ASPHALT CONCRETE PAVEMENTS REINFORCED WITH GEOSYNTHETIC MATERIALS

Abstract

The article sets out to explore reasons for the development of shear strains and rutting in asphalt pavement as well as to suggest and describe the main methods for reducing the deformation. The impact of geosynthetic materials is defined through reological characteristics of asphalt: the modulus of elasticity and the viscosity of asphalt. The research has been conducted on the experimental road section in the city of Vilnius. The measurements have been based on the plate‐bearing test. Sustaining the measurements results is defining the dependency of geosynthetics materials on the depth of rutting and the modulus of elasticity of asphalt concrete. The paper also includes regression equations which show the interdependence of the modulus of elasticity of asphalt concrete and the depth of rutting.
