“…To better characterize the relaxation performance of the three asphalt mixtures, the Burgers model and the generalized Maxwell model are used to fit the curves of the relaxation moduli E(t) of the three types of asphalt mixtures with time, as shown in Figure 6. The expressions of the Burgers model used to fit the relaxation curves and the generalized Maxwell model are shown in Equation (14) and Equation 15, respectively [43][44][45][46]. where G1 and G2 are the relaxation strengths; p1 and p2 are the relaxation times used to characterize the time required for the asphalt mixture to release stress.…”

“…Qin et al [13] introduced that the stress could be dispersed and the development of cracks of asphalt could be suppressed by a stable three-dimensional network made by basalt fibers in the asphalt. Zhang et al [14,15] found that the low-temperature cracking resistance of asphalt mixtures could be improved by adding basalt fibers, but this improvement was different by the variation of basalt fibers content. Zheng et al [16] pointed out that the bending performance at low temperature and fatigue property of asphalt mixtures under the complicated environment such as chloride erosion and freezing-thawing environment could be improved by adding moderate basalt fibers content.…”

To obtain the viscoelastic parameters of asphalt mixtures and analyze the effect of temperatures and modifiers on viscoelastic properties of asphalt mixtures, the creep compliances of the neat asphalt mixture (AM), compound diatomite and basalt fibers reinforced asphalt mixture (DBFAM), and styrene-butadiene-styrene modified asphalt mixture (SBSAM) were tested and calculated by the static creep tests. And the creep compliances of the three asphalt mixtures at −20 °C, −10 °C, and 0 °C are deducted by the time–temperature equivalence principle (TTEP) and Arrhenius equation. Further, the relaxation modulus of the three asphalt mixtures from −20 °C to 50 °C at 10 °C increments are calculated by the convolution integral and Simpson method. Subsequently, the Burgers model, the generalized Kelvin model, and the generalized Maxwell model are applied to analyze the viscoelastic properties of the three asphalt mixtures at different temperatures. The results show that the generalized Kelvin model and the generalized Maxwell model are superior to the Burgers model in describing the variation of viscoelastic properties of asphalt mixtures with loading time. At low temperatures, asphalt mixtures have excellent properties in resisting permanent deformation and releasing internal stress. Besides, the addition of SBS modifier and compound diatomite and basalt fibers modifier can significantly raise the viscosity η1 and the elastic modulus E1 of the asphalt mixture, respectively.

“…Zhang et al performed repeated and multistress creep experiments and made numerical analyses for simulating the performance of asphalt mixtures at high temperatures. They have also carried out numerical analysis to evaluate the distribution effect and reinforcement mechanism of basalt fibre . In another study, Cheng et al used 6‐mm basalt fibres with various contents of 0%, 0.2%, 0.3%, 0.4%, and 0.5% to obtain the optimum content of basalt fibre by considering ordinary pavement performances (i.e., rutting resistance, low‐temperature anticracking, and moisture stability) as criteria.…”

This paper deals with the effect of basalt fibres on fracture toughness of asphalt mixture. For this purpose, basalt fibres with three different contents (i.e., 0.1%, 0.2%, and 0.3% by weight of asphalt mixture) and lengths (ie, 4, 8, and 12 mm) are incorporated into asphalt mixture to prepare fibre-reinforced asphalt mixtures. Fracture tests are then carried out on these mixtures under four different modes of loading (i.e., pure mode I, pure mode II, and two mixed modes of I/II) using semicircular bend (SCB) specimens. The results exhibit that the fracture toughness increases with the enhancement of the fibre content. In addition, increase in the length of basalt fibre results in reduction of the fracture toughness of asphalt mixture. However, the asphalt mixture containing 0.3% of basalt fibres with the length of 4 mm shows the highest fracture toughness compared with other mixtures. It is also found that the basalt fibre improves mode I fracture toughness of asphalt mixtures more significantly than mode II one. Statistical analysis is also performed on the experimental data. Analysis of ANOVA demonstrates that all the three factors investigated in this study (i.e., length of basalt fibre, content of basalt fibre, and mode of loading) have significant influence on the fracture toughness of asphalt mixtures.

The main distresses of asphalt pavements in seasonally frozen regions are due to the effects of water action, freeze-thaw cycles, and so on. Basalt fiber, as an eco-friendly mineral fiber with high mechanical performance, has been adopted to reinforce asphalt mixture in order to improve its mechanical properties. This study investigated the freeze-thaw damage characteristics of asphalt mixtures reinforced with eco-friendly basalt fiber by volume and mechanical properties—air voids, splitting tensile strength, and indirect tensile stiffness modulus tests. Test results indicated that asphalt mixtures reinforced with eco-friendly basalt fiber had better mechanical properties (i.e., splitting tensile strength and indirect tensile stiffness modulus) before and after freeze-thaw cycles. Furthermore, this study developed logistic damage models of asphalt mixtures in terms of the damage characteristics, and found that adding basalt fiber could significantly reduce the damage degree by about 25%, and slow down the damage grow rate by about 45% compared with control group without basalt fiber. Moreover, multi-variable grey models (GM) (1,N) were established for modelling the damage characteristics of asphalt mixtures under the effect of freeze-thaw cycles. GM (1,3) was proven as an effective prediction model to perform better in prediction accuracy compared to GM (1,2).
