“…Furthermore, as compared to base bitumen at 70 °C, the zycotherm modified binder exhibited an improvement of 8.14 % in terms of potential rutting resistance. Previous studies have revealed similar findings, indicating that the addition of zycotherm has an impact on rutting resistance [40,47], but this value rose dramatically after the addition of nanosilica. According to the outcomes of the modified binders, the incorporation of nanosilica to base and zycotherm binders resulted in considerable enhancement levels at all temperatures.…”

The impact of base and zycotherm binders modified with various proportions of nanosilica (i.e., 2 %, 4 %, and 6 %) based on the weight of the binder at high-temperature performance was investigated. Brookfield viscosity, penetration, softening point, and storage stability tests were all conducted on base and modified binders. Moreover, the Superpave rutting parameter (G*/sin δ) and Multiple stress creep recovery (MSCR) were utilized to assess the resistance of binders to rutting. By observing the outcomes of the modified binder tests, the incorporation of nanosilica into the base and zycotherm binders improved temperature susceptibility. Binders modified with nanosilica showed remarkable storage stability at elevated temperatures, as the variation in softening point between the upper and bottom parts was less than 2.5 °C for all binders. Based on the outcomes of the Superpave rutting parameter, the inclusion of nanosilica enhanced the stiffness of the modified binders up to 130 % for 6 % of nanosilica, while the improvement was caused by 6 % of nanosilica with zycotherm was nearly 92 % at 70 °C. The MSCR test revealed that the base and zycotherm binders' recovery (R%) was 27.72 % and 25.99 % for 6 % of nanosilica and 6 % nanosilica with zycotherm, respectively, while the nonrecoverable creep compliance (Jnr) decreased by 56.87 % for 6 % of nanosilica, and 43.23 % for 6 % nanosilica with zycotherm at 100 MPa. The results show that the incorporation of nanosilica is capable of improving the rutting potential regardless of the levels of stress. The rheological characteristics of modified base and zycotherm binders were improved at all concentrations of nanosilica, with the optimal concentration being 6% nanosilica.

“…Ibrahim and Mehan conducted a study involving DSR and BBR assessments. The study revealed increments in rutting parameter (G*/sin δ), fatigue parameter (G* sin δ), creep stiffness, and also the m-values for each zycothermmodified asphalt binder, and when 0.5 % of zycotherm was added, all these outcomes reflected higher values [40].…”

“…They also found that as the content of deicing agent increases the deicing effectiveness is stronger while the mechanical performance degraded [16]. As indicated by research conducted on determining the optimal value of Nano-Zycotherm that is added to the bitumen and asphalt, Nanno-Zycotherm increases resistance when faced with moisture, rutting, exhaustion and cracks at low temperature [17]. Moghadas Nejad et al [18] conducted a study to evaluate the effect of Zycosoil on resistance when faced with moisture in asphalt, and they concluded that Zycosoil increases fatigue life and leads to a better resistance when faced with moisture.…”

The present research studies the effectiveness and efficiency of solutions such as sodium chloride, magnesium chloride and potassium acetate on asphalt pavement to reduce the damage caused by moisture on asphalt pavement in winter. To prevent the stripping problem in asphalt, Nano-Zycotherm with three quantities corresponding to 0.1%, 0.2% and 0.3% weight of bitumen is used in this study. Under the saturated condition with the above solutions, the indirect tensile test performs by applying a freeze–thaw cycle as a means to measure the amount of moisture susceptibility. The results indicate that the asphalt mix containing 0.3% Nano-Zycotherm has a higher indirect tensile strength and tensile strength ratio than asphalt mix containing 0.1% and 0.2% Nano-Zycotherm. Accordingly, Magnesium chloride solution is the most effective deicing material to improve the indirect tensile strength and durability of asphalt pavements when faced with moisture and ice. Article highlights The presence of Nano-Zycotherm in asphalt leads to its increased resistance against stripping. The use of Sodium chloride and potassium acetate deicing solutions causes some damages in asphalt. Considering different solutions, magnesium chloride has the best performance against asphalt stripping.

This study aims to investigate the impact of control and warm mix binders modified with Nano-Silica on the asphalt binder functioning to resist rutting endurance and low-temperature cracking. According to asphalt binder weight, the percentages of Nano-Silica employed in this research were 2%, 4%, and 6%. The control and modified binders were evaluated by performing conventional and rheological tests. The rheological properties were examined by master curves, isochronal plots, multiple stress creep recovery (MSCR), Superpave rutting parameter, and bending beam rheometer. The outcomes implied that the performance of the asphalt binder (with or without ZycoTherm) improved when Nano-Silica was added concerning (G*/sin δ) parameter. The MSCR test demonstrated that the recovery (R %) of the control and warm mix binders improved whereas the non-recoverable creep compliance (Jnr) dropped, implying that Nano-Silica boosted the rutting potential. Moreover, it was observed at different temperatures that the values for the complex shear modulus raised when the phase angle values were reduced. Furthermore, at low temperatures, it is presumed that the performance of Nano-Silica modified asphalt binders will have minimal performance as opposed to the binders prepared with ZycoTherm, which prevents low-temperature cracking.
