Based on the experiments it was found that the operating temperature significantly influenced the resilient modulus of elasticity of asphalt concrete. The study was intended for asphalt concrete used for the wearing course AC 11 S. In the experiment bitumen 35/50 was used which was modified with synthetic wax (Fisher-Tropsh) in the range of 1.5% - 4.0% with steps every 0.5%. The asphalt concrete has been compacted at the optimum characteristic temperature of 125°C. The study revealed a low susceptibility of temperature of asphalt concrete with asphalt low-viscosity in the range of 5°C to 25°C. In addition a negative impact of the lack of compaction level on resilient modulus of elasticity of the asphalt concrete was found.
