The present study aimed to examine the
resistance of pure hot mixes and those prepared with 4% of three different
polymers two types of SBS (styrene-butadiene-styrene) and one type of EVA (ethylene-vinyl-acetate)
against permanent deformation. Samples were prepared with application of
vibration so that they would have 4% void ratio using a roller compactor and
without this application. The effect of vibration application during sample preparation
on the wheel track formation was also assessed in the current study. Wheel
track tests demonstrated that use of additives increased the resistance of hot
mixes against wheel track formation. It was also determined that the most
effective additive was EVA. Furthermore, it was determined that application of
vibration during sample preparation increased the resistance of specimens
against permanent deformation.
