The temperature of compacting and energy influence in dynamics properties of an asphalt mixture
The temperature of asphalt mixtures varies significantly from the plant production to in-situ formation of the pavement structure, especially during the compacting process. Temperature differences from point to point generate segregation, mi- crofissures, and, especially, changes in the mechanical and dynamic properties of the mixture. In this laboratory study the effect of the temperature during the compacting process on the dynamic module, density, stability and flow of an asphalt mixture with gradation 0/10 and asphalt with penetration 60/70 was determined. When the compacting process was conducted at 100 and 150 oC reductions of: around 30%, 5% and 50% were obtained for dynamic module, density and stability, respectively.
