Performance Evaluation of Asphalt Mixtures Modified with Nanomaterials. (Dept. C)

Recently, nanomaterials have been widely used to improve the properties of asphalt binders due their unique properties. This research aims evaluate performance nano-modified with two different types nanomaterials, which are Nano-Silica (NS) and Nano-Clay (NC). Each them was added a 60/70 penetration grade bitumen at concentrations ranging from 1% 4% by binder weight using high shear mixer speed 4000 rpm mixing temperature 145 °C for 60 minutes. A number basic tests were carried out on binders, such as grade, softening point, rotational viscosity, stability storage tests. Moreover, Scanning Electron Microscope (SEM) Fourier Transform Infrared (FTIR) utilized ensure quality process investigate modified binder's internal composition. Furthermore, an additional laboratory study characterize corresponding concrete (AC) mixtures based Marshall stability, indirect tensile strength, moisture susceptibility, double-punch, static creep Based experimental results, best attained when incorporating 3-4% nanoparticles neat binder. In general, addition NS or NC particles positively affected AC mixture in terms debonding, damage, rutting. However, more effective compared can be build sturdy pavements
