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.

The property of asphalt binder plays an important role in the performance of asphalt mixture. The natural rubber additive (NRA) was recommended as a modifier in the preparation of high viscosity asphalt (HVA) binder. Then, the gradation named LASTIKA-13 was adopted to design the high viscosity asphalt mixture (HVAM) according to the orthogonal test analysis and the optimized gradation. The performance of the proposed HVAM was evaluated through a series tests including the permanent deformation at high temperature, moisture stability, low-temperature cracks, and bending fatigue test. The results indicate that the proposed modified asphalt binder shows a comparable property with the conventional modified asphalt binder. The proposed HVAM with the NRA modifier has a superior performance to other conventional mixtures in the temperature susceptibility and resistance to moisture damage. Furthermore, the proposed HVAM was less sensitive to the temperature change and has good performance in terms of resistance to low-temperature cracks, bonding characteristics, and fatigue behaviors.

Researchers have often looked for relationships between mechanical properties of asphalt mixtures and rheological properties of binders when assessing the resistance of mixtures and binders to permanent deformation. When mixtures are subjected to deformation on application of a stress, aggregates act as load-bearing entities, and binders deform in response to applied stress. Intuitively, a correlation must exist between the properties of mixtures and binders. However, a good correlation usually is not observed. There could be a number of reasons for the observed poor correlations, including ( a) variability in the data or a possible change in the microstructure of two-phase, polymer-modified asphalt in the presence of aggregates, or ( b) strong interactions between the aggregate and the binder that, of course, are not reflected in the binder properties. In such cases, there are reasons to believe asphalt mastics might provide a better correlation because they would account for at least the physicochemical aspects of the aggregate–binder interaction. The present work compared asphalt mixture data initially with mastic data and then separately with binder data. The mastic and binder rheological data were generated with the same equipment under identical conditions of measurement to identify which one correlates better with the mixture data. A good correlation was obtained in only one case when Superpave® shear tester data for mixtures were compared with the dynamic shear rheometer data for binders. In all cases analyzed in this work, no correlation was found between the permanent deformation for mixtures and the rheological properties of the mastics.

The use of cup lump rubber as an additive in asphalt binder has recently become the main interest of the paving industry. The innovation helps to increase the natural rubber consumption and stabilize the rubber price. This study evaluates the mechanical performance of cup lump rubber modified asphalt (CMA) mixture in terms of resilient modulus, dynamic creep and indirect tensile strength under aging conditions. The CMA mixture was prepared using dense-graded Marshall-designed mix and the observed behavior was compared with that of conventional mixture. From the results, both mixtures passed the volumetric properties as accordance to Malaysian Public Work Department (PWD) specification. The addition of cup lump rubber provides better resistance against permanent deformation through the enhanced properties of resilient modulus and dynamic creep. Furthermore, the resilient modulus of CMA mixture performed better under aging conditions.

The objectives of this study were to determine the blending parameters of coconut shell powder (CSP) modified asphalt binder and to evaluate the rheological properties of CSP modified asphalt binder. CSP of 2%, 4%, 6%, 8% and 10% by weight of asphalt have been incorporated into an unaged 80/100 asphalt mix in order to improve its performance. The influence of the additives on the physical and rheological properties was evaluated with penetration test, softening point, storage stability, dynamic shear rheometer test (DSR), and Field Emission Scanning Electron Microscope (FESEM). The aging of asphalt binders was simulated in a laboratory by using Rotational Thin Film Oven (RTFO). The results showed that the addition of CSP into virgin binder was decreasing the penetration value and increasing the softening point temperature compared to the original binder. On the rheological effect, for unaged modified binder, higher CSP resulted higher G*/sin δ especially at lower temperature compared to the unaged control binder. Besides, for the aged modified binder, stiffness was lower than the control aged binder for all temperature.
