## 1 Introduction  
Due to the good performance and riding quality, along with easy maintenance and repair, asphalt pavement has increased year by year in China [1]. However, the temperature sensitivity of asphalt materials is high and the mechanical properties of asphalt pavement will degrade under large temperature difference [2]. Northeast China belongs to the seasonal frozen region and the average temperature in winter can reach \(-20\)\({}^{\circ}\)C and above \(20\)\({}^{\circ}\)C in summer. In order to improve the performance of asphalt pavement, reduce the damage of pavement, and extend the service life of pavement, nanomodification and fiber modification technologies have been applied in asphalt mixture. Nanotechnology is a new technology that has gradually emerged in recent years. Nanomaterials have been gradually applied as asphalt mixture modifiers due to their special properties not found in macroscopic materials. [PERSON] et al. evaluated moisture susceptibility of hot mix asphalt (HMA) with and without Zycosoil as a nano-organosilane anti-stripping additive and hydrated lime in the form of slurry. The results found that use of Zycosoil additive will increase adhesion bond between the aggregates and asphalt binders, and in turn influences the moisture resistance of the mixture to moisture damage [3]. [PERSON] studied the effects of using nano-CaCO\({}_{3}\) as an antistrip additive on moisture susceptibility of asphalt mixtures have been assessed using the surface free energy (SFE) method and modified Lottman test. Adding nanomaterials lead to the decrease of the acid component of SFE and increase of basic component of SFE for the asphalt binder that lead to an increase of adhesion between the asphalt binder and sensitive aggregate against moisture damage [4]. Nano-TiO\({}_{2}\) is a commonly used nanomodified material. [PERSON] et al. found that nano-TiO\({}_{2}\) could effectively improve the viscosity, anti-rutting, and anti-fatigue properties of asphalt mixture [5]. [PERSON] et al. used nanomaterials to modify SMA and the test results showed that nano-TiO\({}_{2}\) could improve the anti-rutting ability and splitting strength ratio and prolong the service life of an asphalt mixture [6]. [PERSON] et al. evaluated the microstructure and chemical properties of nanocomposite modified asphalt by X-ray and scanning electron microscopy. It was found that the addition of nanomaterials improved the fatigue resistance of asphalt mixture [7]. There are many kinds of fiber modifiers used in asphalt mixtures in recent years, such as polyester fiber, lignin fiber, carbon fiber, glass fiber, basalt fiber, etc. Different fiber modifiers have their own advantages and disadvantages. The low-temperature crack resistance of asphalt mixture is the main problem in the frozen region of northeast China. Compared with other fibers, basalt fiber is a mineral fiber that is abundant and easy to obtain in northeast China. Also, it will not cause environmental pollution. Basalt fiber has some advantages in terms of modifying road performance of asphalt mixtures. [PERSON] studied the pavement performances of basalt fiber, lignin fiber, and polyester fiber modified asphalt mixtures and found that the performance of the basalt fiber modified asphalt mixture was superior to that of the others [8; 9]. [PERSON] et al. studied the usability of basalt fibers in order to bear the stresses occurring at the surface layer of pavement and the optimum value of the fiber ratio leading to the optimum stability value was determined [10]. [PERSON] found that basalt fiber, at the optimal fiber content, could improve the water stability and high-temperature stability of the asphalt mixture more effectively than lignin fiber and polyester fiber [11]. [PERSON] studied the asphalt adsorption property, shear performance, crack resistance, and high-temperature rheological properties of asphalt modified by basalt fiber, lignin fiber, and polyester fiber.
