“…As seen in Figure 9B, the structure of dispersed hydrophobic clay minerals can be intercalated or exfoliated [94,153]; and the latter one is more effective for using in PMB. By adding a proper content of hydrophobic clay minerals, the improved storage stability, increased viscosity, higher stiffness and better rutting resistance of PMB can be observed [92,93]. Furthermore, an improvement in ageing resistance can be achieved by clay platelets' hindering the penetration of oxygen in PMB [134], which can be presented with Figure 9C.…”

“…Furthermore, an improvement in ageing resistance can be achieved by clay platelets' hindering the penetration of oxygen in PMB [134], which can be presented with Figure 9C. Excessive clay minerals, however, may destroy the elastic properties of PMB [93]. Additionally, the ideal exfoliated structure of PMB with hydrophobic clay minerals is hard to obtain; and their use only lead to limited improvements in low-temperature properties, ductility and elastic recovery [93].…”

“…Researchers have attempted different ways to remove these drawbacks, including sulfur vulcanization [82][83][84][85][86][87], adding antioxidants [22,88,89], using hydrophobic clay minerals [90][91][92][93][94][95][96][97][98] and functionalization (including application of reactive polymers) [10,[99][100][101][102][103][104][105][106][107][108][109][110][111][112][113]. Including saturation [2,12,138], which has been discussed above, some attempted measurements for removing PMB's drawbacks are listed in Table 2 with their advantages and disadvantages.…”

Abstract. Advances and challenges in the field of bitumen polymer modification for road construction during the last 40 years are reviewed in this paper. The history of bitumen polymer modification is described chronologically. Some popular plastomers and thermoplastic elastomers in bitumen modification are discussed regarding their advantages and disadvantages, including polyethylene (PE), polypropylene (PP), ethylene-vinyl acetate (EVA), ethylene-butyl acrylate (EBA), styrene-butadiene-styrene (SBS), styrene-isoprenestyrene (SIS) and styrene-ethylene/butylene-styrene (SEBS). Although these polymers all improve bitumen properties to some extent, there are still some drawbacks limiting the future development of bitumen polymer modification, such as high cost, low ageing resistance and poor storage stability of polymer modified bitumen (PMB). Researchers attempted various ways to remove these drawbacks. Some technical developments for removing drawbacks are reviewed in this paper, including saturation, sulfur vulcanization, adding antioxidants, using hydrophobic clay minerals, functionalization and application of reactive polymers. The future development of polymers for bitumen modification is analyzed as well. Since it is currently challenging to perfectly achieve all expected PMB properties at the same time, some compromised recommendations are given in this paper, among which greatly enhancing the properties with an acceptably high cost, significantly reducing the cost with relatively poor properties and their combinations. Functionalization is emphasized as a promising way to enhance the properties of currently used polymers and develop new-type polymer modifiers with much greater success in the future. It is also recommended that future research on bitumen polymer modification focuses more on function development towards enhancing: adhesion with aggregates, long-term performance and recyclability.

Nanotechnology is one of the most important research areas and is presented in the vast fields of knowledge such as road construction industry has been surrounded. This paper has focused on the potential benefits of nano particles for modification of asphalt mixtures. Nano Al 2 O 3 due to its unique properties can improve the dynamic characteristics of hot mix asphalt. Fatigue life of asphaltic samples is determined with indirect tensile fatigue tests by using of UTM. The results show that fatigue life of modified asphalt mixtures in compare with conventional mix is significantly increased. Beside, based on experimental results and numerical analyses, a new model is presented for prediction the fatigue behavior of asphalt mixtures modified with nano Al 2 O 3 . This model can completely characterized the fatigue performance of modified asphalt under dynamic loading conditions and different temperatures.

“…The addition of nanoclay into asphalt is useful to improve the short-and long-term aging resistance of the modified asphalt binder. At the same time, it contributes to the physical, mechanical, and rheological properties of modified asphalt binder [5][6][7][8][9]. In addition, nanoclay can improve the rutting resistance of styrene-butadienestyrene (SBS) modified asphalt binder [10].…”

To investigate the effects of nanoparticle content, storage time, and storage temperature on the storage stability of asphalt binders modified by nanoparticles, hot tube storage tests, softening point tests, and dynamic-shearing rheometer (DSR) tests were adopted to evaluate the properties of two kinds of nanotitanium dioxide (TiO 2 ) modified asphalt binders. A statistical one-way analysis of variance (ANOVA) test was employed to analyze the effects of those variations on the storage stability of the nano-TiO 2 modified asphalt binders. The results indicated that the softening point, the failure temperature, the dynamic-shear viscosity, and | * |/sin( ) of the binders increased with nanoparticle content. The storage stability of the binders decreased with nanoparticle content. The impact of storage time on the storage stability of the binders was remarkable when the storage time was more than 48 h. Moreover, the storage stability of the binders at low temperatures was better than that at high temperatures. Based on the one-way ANOVA, the size of nanoparticle had little influence on the storage stability of the nano-TiO 2 modified asphalt binders in this study. Reducing the nanoparticle size cannot effectively enhance the storage stability of the nanoparticle modified asphalt binder due to the agglomeration of nanoparticle.
