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.

“…To evaluate the aging behavior of nanosilica modified binders, FT-IR spectral bands signal centered around 1600 cm -1 to 1700 cm -1 that show carbonyl functional groups C=O formation as a result of binders exposure to oxygen under high temperatures are used (Feng et al, 2013;Mouillet et al, 2008).

Performance of bituminous binders in terms of rutting and fatique is known to be related with rheological characteristics of asphalt binders. To enhance the rheological properties of binder, a modification using composite polymer and inorganic nanosilica becomes recognized as it highly improves the flow and deformation of the modified binders. This study investigates the application of polyethylene polymer and inorganic nanosilica for enhancing rheological properties as well as the oxidative aging resistance of asphalt binders. Conventional and Superpave binder test techniques. Using dynamic shear rheometer (DSR) was used to investigate the performance and rheological behaviors of the nanocomposite-modified binders. Changes in chemical bonding and morphological properties due to nanosilica were also investigated using Fourier transform infrared spectroscopy (FT-IR) and field emission scanning electron microscopy (FE-SEM). Nanosilica was added into polymer modified bitumen at different percentages (1% to 6%) by weight of bitumen binder. Results of the investigations show that composite nanosilica/polyethylene modified binders will not undergo phase separation during storage due to improved viscoelastic properties. The Superpave rutting parameter shows that nanosilica modified binders have higher resistance to permanent deformation both before and after rolling thin film oven (RTFOT) aging. FE-SEM and FT-IR investigation shows that nanosilica modified binders are less susceptible to oxidative aging hardening.

“…However, SBS-MB also has disadvantage of easily aging when exposed to the complex environmental agents, such as heat, oxygen, ultraviolet (UV) light, rain and wind, which result in decrease of bitumen properties such as low-temperature cracking and stripping, and shorten the lifetime of waterproofing membrane dramatically [3][4][5] . UV light plays a major role in accelerating bitumen membrane aging among those complex factors, nevertheless, the influence of UV on bitumen aging is ignored in laboratory simulations of aging [6][7][8] . The rate of the UV light energy to the total solar energy is only 5%-7%, but those UV rays with short wavelength (290-400 nm) and high-energy photons (412-299 kJ/ mol) induce the changes of the chemical composition of SBS-MB, leading to the performance deterioration of products.…”

Layered double hydroxides (LDHs)/styrene-butadiene-styrene (SBS) copolymer modified bitumen was prepared by melt blending. The effect of LDHs on the ultraviolet (UV) aging behavior of SBS modifi ed bitumen was investigated. The changes of chemical structures of modifi ed bitumen before and after UV aging were characterized by Fourier transform infrared spectroscopy (FTIR). The results show that LDHs obviously reduce the variation of softening point and low temperature fl exibility of SBS modifi ed bitumen under different UV radiation intensities, which indicates that the UV aging resistance performance of SBS modifi ed bitumen is improved effectively by LDHs. Compared with SBS modifi ed bitumen, the changes of carbonyl, sulfoxide and butadienyl of LDHs/SBS modified bitumen decrease significantly after UV aging according to FTIR analysis, demonstrating that the oxidation and degradation reactions of SBS modifi ed bitumen were restrained effectively by adding LDHs.
