Abstract: The research reported in this paper evaluates a novel bitumen modification through the use of different inorganic nanoparticles, such as nanozinc oxide, nanosilica, and nanotitanium dioxide. In order to improve the dispersion ...

Abstract: The effects of various amounts of organic montmorillonite (OMt) on the morphology and physical properties of bitumen before and after ultraviolet (UV) aging were investigated. The microstructures of OMt modified bitumens ...

Abstract: Ultraviolet (UV) radiation causes asphalt aging and thus influences its performance. In this research, a composite light stabilizer was prepared to increase the light stability of matrix asphalt. Benzotriazole UV absorber ...

Abstract: Fragility functions are used in the vulnerability analysis of structures considering different sources of uncertainties. In this research, a framework to develop time-dependent fragility functions for circular tunnels ...
