Impact of Rejuvenator-Modified Mastic on Asphalt Mixture Stiffness
Câmara, Gustavo; Azevedo, Nuno Monteiro; Micaelo, RuiPublisher Copyright: © 2023 by the authors.; Encapsulated rejuvenators embedded in asphalt mixtures are a promising technology to extend the service life of asphalt pavements. However, their effects on the asphalt mixture’s performance still need to be properly understood. A recently developed three-dimensional discrete element method framework enables the evaluation of non-homogeneous distributions of the reju...
3D DEM model simulation of asphalt mastics with sunflower oil
Câmara, Gustavo; Micaelo, Rui; Monteiro Azevedo, NunoPublisher Copyright: © 2023, The Author(s).; A three-dimensional particle model, based on the asphalt mastic micro-structure representation following a discrete element model framework, was developed to investigate the influence of sunflower oil (rejuvenator) on the rheological properties of asphalt mastic. Dynamic shear rheometer tests in laboratory, for a frequency range of 0.1–20 Hz and temperatures in a ran...
