Numerical bond assessment of carbon-epoxy stepped-lap joints
Biscaia, Hugo C.; Micaelo, Rui; Cornetti, Pietro; Almeida, RaquelPublisher Copyright: © 2023 The Author(s); With the main purpose of obtaining lightweight and durable structures, bonding techniques have improved significantly in several industries. Depending on the type of structure, joining different components with different materials may require different joint geometries, which may perform better or worse. Still, only the bond performance of a very limited number of join...

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...
The use of bio-oil from biodiesel production for enhancing the bitumen healing
Cabette, Marina; Micaelo, Rui; Pais, JorgePublisher Copyright: © 2023 The Author(s); Road pavements are exposed to traffic and temperature effects that produce distress, mainly cracking that leads to pavement failure, after which rehabilitation actions are necessary to extend pavement life. Bio-rejuvenators have been used to recover the bitumen properties lost due to fatigue of the asphalt mixtures and ageing due to temperature variations and oxidation...
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...

Chastre, Carlos; Ribeiro, Álvaro; Ribeiro, Diogo; Neves, José; Pinho, Fernando F. S.; Neves, Maria Graça; Biscaia, Hugo; Faria, Paulina; Micaelo, RuiThe world is undergoing major technological changes and this era is already considered the fourth industrial revolution. These new technologies have profound implications for the way we live, work, and interact with each other. For this reason, the 3rd Conference on Testing and Experimentation in Civil Engineering (TEST&E 2022), was focused on the way Smart Technologies affect the development of Civil Engineeri...
