EXPERIMENTAL STUDY OF EFFICIENCY APPLICATION OF REINFORCING SYNTHETIC MATERIALS ADFORS GLASGRID FOR INCREASE RUTTING RESISTANCE AND CRACK RESISTANCE OF ASPHALT CONCRETE PAVEMENTS OF HIGHWAYS
DOI: 10.33868/0365-8392-2024-2-279-100-113
Abstract. The effectiveness of using Adfors GlasGrid® reinforcing synthetic materials to increase the rutting resistance and crack resistance of asphalt concrete pavements of highways was experimentally studied. It has been experimentally confirmed that reinforcing the top layer of an asphalt concrete pavement with Adfors GlasGrid® reinforcing synthetic materials ensures reliable adhesion of asphalt concrete layers and can significantly increase the rutting resistance, fatigue life of the asphalt concrete pavement and its tensile strength in bending. Reinforcement of asphalt concrete pavement with Adfors GlasGrid® reinforcing synthetic materials allows increasing rutting resistance, that is, reducing the rut depth and total rutting area by 19–35%. At the same time, studies have shown that Adfors GlasGrid® reinforcing synthetic materials have confirmed their effectiveness when used under the top layer of cover. A study of the effect of reinforcement of asphalt concrete pavement on the adhesion of the upper and lower layers of asphalt concrete showed that all studied synthetic reinforcing materials Adfors GlasGrid® meet European requirements for the adhesion of reinforced asphalt concrete layers. A study of the influence of reinforcement of an asphalt concrete pavement on its fatigue resistance showed that the reinforcement of an asphalt concrete pavement with Adfors GlasGrid® reinforcing synthetic materials makes it possible to increase the number of load cycles up to a loss of fifty percent of the complex deformation modulus by 2.6 – 5.9 times compared to a non-reinforced pavement. Experiments have confirmed that reinforcing an asphalt concrete pavement with Adfors GlasGrid® reinforcing synthetic materials increases its tensile strength in bending. This confirms the possibility and feasibility of using Adfors GlasGrid® reinforcing synthetic materials under the top layer of asphalt concrete pavement, including on bridges and overpasses, to increase the crack resistance, rutting resistance and durability of asphalt concrete pavements. Keywords: rutting resistance, crack resistance of asphalt concrete pavements, asphalt concrete pavements of highways, durability, reinforcing synthetic materials, reinforced asphalt concrete layers.
