Influence of Method for Basalt Fibers Introduction on Physical-Mechanical Indicators of Composite Asphalt Concrete Mixes

The introduction of fibers and threads into the composition of composite asphalt concrete mixes is a method for improving the stability of asphalt concrete to external loads according to domestic and foreign sources. The introduction of long length elements – threads, fibers or wire – at fulfillment and consistency of quality indicators as well the convenience of its use is an insolvable problem at present. The introduction of small size (discrete) elements makes it possible to achieve their uniform distribution (dispersion) in the mixture and to obtain a “composite” material with higher physical-mechanical properties in the finished structural element. In the course of work, experimental compositions of composite disperse- reinforced asphalt concrete mixes were selected, the influence of the method of introducing the basalt fiber into the mix on their properties was determined; experiments on fine-tuning of conditions of preparation and introduction of the fiber into composite asphalt concrete compositions were conducted. The study conducted makes it possible to determine the effi- ciency of the method for introducing the preliminary prepared basalt fiber into the asphalt concrete mix for improving indicators of physical-mechanical properties of asphalt concrete in pavements of highways
