“…This is an important means to prolong the service life of asphalt pavement. At present, the common asphalt modifier can be divided into the polymer-modified material and the inorganic modified material [6][7][8][9][10][11][12][13][14]. By the inorganic modified material utilization such as diatomite and basalt fiber as the modifier, not only the asphalt performance could be enhanced, but also the polymer modifier pollution to the environment could be avoided.…”

In order to improve the performance of asphalt mastic, some researchers have added diatomite or basalt fiber as a modifier to the asphalt mastic, and the results show that some properties of the asphalt mastic were improved. For the simultaneous addition of diatomite and basalt fiber, two kinds of modifier, compound modified asphalt mastic had not been reported; in this paper, thirteen groups of diatomite and basalt fiber (DBFCMAM) compound modified asphalt mastic with different content were prepared to study the performance. Softening point, cone penetration, viscosity, and DSR tests were conducted, for the high temperature performance evaluation of DBFCMAM, whereas force ductility and BBR tests were used in the low temperature performance study of the DBFCMAM. The results demonstrated that the high temperature performance of DBFCMAM was increased; moreover, the low temperature performance of DBFCMAM improved by diatomite and basalt fiber according to the results of the force ductility test; however, the conclusion of the BBR test data was inconsistent with the force ductility test. In summary, the high temperature and low temperature properties of DBFCMAM had been improved.

Graphene nanoparticles (GNPs) added styrene-butadiene-styrene (SBS)-modified asphalt suffers from serious compatibility and agglomeration problems. To tackle these problems, in this study, graphene oxide (GO) was mixed with bromobutane to synthesize butylated graphene oxide (C 4 H 9 -GO) composite, which was in turn compounded with SBS for the preparation of C 4 H 9 -GO/SBS-modified asphalt. C 4 H 9 -GO/SBS-1.0-modified asphalt exhibited the best performance in terms of 11.4% increased softening point, 19.3% increased ductility, and 10.2% reduction in penetration as compared to 5% SBS-modified asphalt. Dynamic shear rheometer and multistress creep recovery tests showed that at 1.0% C 4 H 9 -GO contents, C 4 H 9 -GO/SBS composite-modified asphalt exhibited the best high-temperature performance and low stress sensitivity. Microscopic characterization of C 4 H 9 -GO via Fourier transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy revealed successful bonding between C 4 H 9 and GO, increasing interlayer spacing in GO. Atomic force microscopy and scanning electron microscopy analysis showed the superior elasticity of C 4 H 9 -GO than GNPs. Differential scanning calorimetry analysis indicated that C 4 H 9 -GO sheets can be stabilized by SBS through π-π stacking with the polystyrene chains. This study awarded to the preparation of novel C 4 H 9 -GO/SBS-modified asphalt with superior mechanical property can be deemed of potential value and applications in construction and highway industries.GNPs have also been applied as modifiers for the preparation of modified asphalts. Han et al., 10 via in situ polymerization strategy, synthesized polystyrene-GNPs (PS-GNPs) and added them to styrene-butadiene-styrene (SBS)-modified asphalt, which exhibited improved softening point and high-temperature rutting resistance performance than the parent asphalt. The National Cooperative Highway Research Program found that compared to conventional asphalt binders, GNPs-enhanced asphalt binders exhibit excellent flexural strength at low temperatures, but the fracture energy of Additional Supporting Information may be found in the online version of this article.

“…Waste materials such as rubber of waste tires, oil shale ash, medical ash, and toner waste [1][2][3][4] have been used to enhance the properties of asphalt binders used in the hot-mix asphalt technology. In addition, some researchers took advantage of agricultural tree and plant waste such as the empty fruit bunch of date and oil palm trees [5] to produce cellulose fiber to be used as additives in the asphalt binder.…”

is study intended to evaluate the use of waste stone sawdust filler with asphalt binders and compare the mechanical properties of the waste filler-asphalt mastic with those of the asphalt mastic produced using the typical limestone filler. e mastics were prepared at four filler-to-asphalt ratios by volume of asphalt binder: 0.05, 0.10, 0.20, and 0.30. A dynamic shear rheometer (DSR) strain-controlled frequency sweep test was used to evaluate the properties of the control asphalt binder and the mastics. e test used a constant strain of 10% and loading frequencies of 10, 5.6, 3.1, 1.78, 1.0, 0.56, 0.31, 0.178, and 0.1 Hz and was conducted at wide range of temperatures: 10, 20, 30, 40, 50, 60, and 70°C. e test measured the complex shear modulus (G * ) value and the phase angle for the binder and the mastics. e findings of this study showed that the stone sawdust filler demonstrated higher resistance to fatigue and rutting behavior than the limestone filler. However, the elastic behavior of the two asphalt mastics was nearly similar and increased with the increase in volume ratio. It was also found that the best-fit model described the relationship between the volume ratio and each of |G * |/sin δ and |G * |cos δ, and the mastic-to-binder modulus ratio was the exponential model with high coefficient of determination (r 2 ). e differences in the G * value between the limestone filler and the stone sawdust filler were relatively insignificant particularly at low loading frequencies and high temperatures. Finally, the mastic-to-binder modulus ratio decreased with the increase in loading frequency. BackgroundAlthough asphalt mixture is approximately composed of only 5% asphalt binder and the remaining is aggregate, the mechanical properties and behavior of asphalt binder affect significantly the properties of asphalt mixture and hence play a big role in the performance of asphalt pavements.e complexity of asphalt binder comes from the viscoelastic nature of this material. Its properties and behavior are time and temperature dependent. In addition, the mode of loading impacts this behavior. High stiffness and elastic behaviors are desired properties for asphalt binders used in hotmix asphalt design and production. High stiffness is required to resist rutting under heavy loads in pavements. On the other hand, elastic behavior is also needed to recover and heal part of the deformations in pavements under loading to minimize fatigue cracking. Researchers in the asphalt technology field have been always attempting to enhance and optimize properties of asphalt used in the pavement construction.Modification of asphalt binders is done by utilizing several modifiers that are available on a wide spectrum in the industry. Some of these modifiers are manufactured so that they are used in the asphalt technology at a feasible cost. However, other modifiers are waste or recycled materials that can be used in asphalt to serve twofold purpose: (1) enhancing the properties of asphalt and (2) helping to clean environment.
