UTICAJ SINTETITIČKIH VLAKANA NA BAZI ARAMIDA I POLIOLEFINA NA FIZIČKO-MEHANIČKE I DINAMIČKE KARAKTERISTIKE ASFALTNE MEŠAVINE
Mixture of fiber used in this paper is made of fiber based on aramid and polyolefin, known for its strength, durability and bonding properties. This is a new technology with the use of super material that allows the formation of 3D skeletal reinforcing mesh in asphalt. Fibers are used to improve the performance of asphalt mix in terms of resistance to permanent deformation, reflecting cracks and cracks due to the fatigue of the pavement construction. The economic effect is expressed through the reduction of the thickness of the asphalt layer and the extension of the exploitation period of asphalt.
The aim of this paper is to compare the characteristics of asphalt mix AB 11s with and without fiber addition, such as stiffness modulus, resistance to permanent deformation and fatigue resistance. Also, resistance to rutting, water sensitivity and indirect tensile strength has been shown improvements the characteristics of asphalt mix with fiber reinforcement.
