Agencies have been increasing their use of polymer modified asphalt binders in recent years to address performance issues and lengthen the useful life of their pavements. When deployed these materials likely experience strain levels exceeding their linear viscoelastic (LVE) limits. The same situation exists in non-polymer modified asphalt binders as well, but the effect may be more pronounced in polymer modified systems because of their bi-phasic nature. In this study, terminally blended crumb rubber (CR-TB) modified asphalt is studied to understand and quantify the nonlinear viscoelastic response under large strains. The CR-TB binders are extensively used in pavements subjected to high vehicular loads and extreme climatic conditions; thereby, their response under large strains becomes more critical. The current standard characterization techniques are based on LVE response using small amplitude oscillatory shear rheology only and do not consider the behavior of binders under large strains. In this study, large amplitude oscillatory shear (LAOS) rheology is used as a framework to more thoroughly investigate the complete response of the CR-TB modified asphalt binder under large strains at 30°C, 40°C, 50°C, and 60°C and at the frequencies of 0.5, 1, and 5 Hz. The LAOS response is analyzed using Fourier-transform rheology and the orthogonal stress decomposition method involving Chebyshev polynomial representation. It is found that nonlinearity manifests greatly in this study material as strain levels increase and frequencies decrease. The relative nonlinearity increases with increasing strain amplitude and is more significant towards lower end of the tested temperature range. The CR-TB binder shows strain-stiffening/softening and shear-thinning/thickening behavior depending upon a specific temperature, strain level, and frequency.

This paper presents a review of nanoclay as a latest technology in order to overcome problem due deterioration such as rutting, fatigue, stripping, cracking and so on. Nowadays, with increasing of traffic volume and heavy vehicle conditions of existing road totally fail in order to accommodate this situation during design period. In order to manage this problem the new technology had been create and apply. Previous researches prove that nanotechnology has potential solution to enhance the performance and durability of construction materials. Material properties were characterized using Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD). According to previous research there were proved that addition of nanoclay lead great improvements on permanent deformation and fatigue life of hot mix asphalt (HMA). In addition the overall performance of nanoclay as polymer modified asphalt binder was improve in terms of rutting and fatigue cracking resistance compare to non-modified asphalt binder. Therefore, nanoclay itself would be an alternative as modifier to use in the bitumen to improve the lifetime of asphalt pavements.
