The High Temperature Performance Evaluation of Polymer/Nanocomposite Modified Asphalt Cement

The current study focuses on the effect of Acrylate-styrene-acrylonitrile (ASA)/Nanosilica (Si) modified binders complex modulus (G*) and rutting resistance parameters (G*/ sinδ) Asphalt Cement (AC). Four different blends including base binder polymer nanocomposites which were formed by blending 5% ASA to with addition nanosilica at 3, 5 7% weight subject investigations. Conventional Dynamic Shear Rheometer (DSR) testing procedures conducted as well morphology analysis using Fourier Transform Infrared Spectroscopy (FT-IR). rheological characteristics AC analysed master curves, isochronal plots parameter plots. Test results revealed that G* G*/ sinδ all samples significantly enhanced compared binder. Multiple Stress Creep Recovery (MSCRT) 100 Pa 3200 showed that, non-recoverable compliance was reduced elastic recovery improved. Optimum concentration found be ASA/Si composite, further nanocomposite resulted in lower enhancement properties due occurrence agglomeration between composite
