“…For a thick layer of pavements, mixing of hydrated lime by a wet method of mixing give better results as compared to the dry method of mixing for fatigue life. However, for thin layers, mixing 1-2% of hydrated lime as filler material gives better results of fatigue life [13]. The addition of 1-2% of hydrated lime in un-aged asphalt mixture can be beneficial for fatigue life improvement [14].…”

The major distresses in asphalt pavements are rutting, fatigue, and adhesion loss (moisture susceptibility). In this research study, two substitution fillers (Cement and Lime) were used with two different aggregate quarries (based on minerals composition) to evaluate the relatively most beneficial combination of both fillers as well as an aggregate quarry to enhance the performance life of asphalt pavements, especially in under-developed countries. Four basic tests, (Asphalt Pavement Analyzer, Four Points Bending Beam, Dynamic Modulus, and Rolling Bottle Test) that used for the most desired properties of any asphalt pavement, were utilized to access the performance properties of modified asphalt mixture. Based on all laboratory test results this research study concludes that replacement of aggregate filler with hydrated lime and cement has a beneficial effect on asphalt mix performance and to save investment by using raw material. Substitution filler improves the high-temperature rut performance and intermediate temperature fatigue performance of asphaltic concrete mixture up to 25% to that of the conventional mixture. At the same time, substitution filler has more beneficial to improve 70% adhesion properties to that of the conventional mixture.

“…In recent years, plenty of studies have been conducted to use carbon black (CB) as a modifier for asphalt binders [12][13][14][15][16][17][18][19][20]; these works are a good start towards enlarging the application field of CB. Previous research investigated the modified effect of CB on the workability or mechanical properties of asphalt binders and their mixtures, with the results indicating that CB had good compatibility with asphalt binders and a reinforcement effect on asphalt binders, and decreased the resistivity of asphalt [12]; it could improve the complex modulus [13] and anti-aging performance (ultraviolet aging and thermo-oxidative aging) of asphalt binders [15], as well as enhance the anti-rutting performance of asphalt mixtures at high temperatures [14].…”

“…However, there was no consistent conclusion about the effect on low-temperature performance: some studies showed that carbon black could improve the low-temperature performance of asphalt, while others showed that it cannot or that it has no effect [16,17]. However, in general, micrometer and nanometer powder materials always have a stiffening effect on asphalt and can reduce the anti-crack property of asphalt at low temperatures [18][19][20].…”

It is of great benefit to the environment and the economy to use discarded tires pyrolysis carbon black (TPCB) nanoparticles as a modifier for asphalt binders. A base asphalt binder with 60/80 penetration (GF-70) was selected to prepare the TPCB-modified asphalt binder (TPCB/GF-70) with a 15% dosage of TPCB by the melt blending method. The test instruments, such as Fourier transform infrared spectroscopy, laser particle size analyzer, and thermogravimetric analyzer, were used to study the characteristics of TPCB. The physical performance of GF-70 and TPCB/GF-70 were tested and the rheological properties were also tested with a dynamic shear rheometer to investigate TPCB's effect on the performance of GF-70. In addition, the aromatic hydrocarbon oil (AHO) was used as the softening agent for TPCB/GF-70. The pavement performance of AC-13 and AC-20 was studied to evaluate the comprehensive effect of TPCB and AHO on the pavement performance of asphalt mixtures. Results show that a 15% dosage of TPCB can significantly improve the anti-rutting performance of GF-70, and decrease the low-temperature performance of GF-70 within one PG grade. AHO can obviously improve the low-temperature performance of TPCB/GF-70, but does not significantly decrease the high-temperature performance. With the addition of AHO and a 0.1% higher oil aggregate ratio, TPCB tends to significantly improve the anti-rutting performance and the low-temperature performance of TPCB-modified mixtures; the moisture stability of TPCB and AHO composite modified mixtures satisfies the requirement of water stability.

“…Many researchers investigated the possibility of relating the properties of asphalt mastic and mortar to the corresponding asphalt mixture behavior showing that type, size, grading and particles concentration significantly affect the final performance [ 9 , 10 , 11 , 12 , 13 , 14 ]. In most cases, an improvement in rutting, fatigue cracking, and moisture damage resistance was observed coupled to an overall stiffening effect [ 10 , 11 , 15 , 16 , 17 ]. For example, the research conducted at the École Nationale des Travaux Publics de l’État (ENTPE) in France, demonstrated that when ultra-fine particles are incorporated with asphalt binder, a considerable stiffening effect is observed especially at higher temperature [ 7 , 14 , 15 ].…”

“…However, not much attention was devoted to the effect of the inclusions of finer particles at low temperature. In most of the cases the response of mastic and mortar was only addressed in terms of complex modulus, and hence stiffness, while, the response in terms of relaxation properties, the evolution of thermal stress and the associated critical cracking temperature were not evaluated together with the high temperature performance [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. Among the different reinforcement materials, Electric Arc-Furnace Steel Slag (EAFSS) represent a valuable option given the large amount available coupled to the environmental benefits associated with the recycling process of this industrial by-product [ 18 , 19 , 20 , 21 , 22 ].…”

In this paper, the possibility of improving the global response of asphalt materials for pavement applications through the use of hydrated lime and Electric Arc-Furnace Steel Slag (EAFSS) was investigated. For this purpose, a set of asphalt mortars was prepared by mixing two different asphalt binders with fine granite aggregate together with hydrated lime or EAFSS at three different percentages. Bending Beam Rheometer (BBR) creep tests and Dynamic Shear Rheometer (DSR) complex modulus tests were performed to evaluate the material response both at low and high temperature. Then, the rheological Huet model was fitted to the BBR creep results for estimating the impact of filler content on the model parameters. It was found that an addition of hydrated lime and EAFSS up to 10% and 5%, respectively, results in satisfactory low-temperature performance with a substantial improvement of the high-temperature behavior.
