In this study, a novel multiscale synergistic reinforced polyester fiber (PET) was prepared by a bionic coating and electrostatic synergism. The three‐dimensional (3D) interconnected structure was developed on the surface of PET by electrostatically synergistic hybridization of negatively charged 2D lamellar graphene oxide (GO) and positively charged 1D hollow tubular aminated halloysite nanotubes (HNT). These fibers were applied to prepare fiber incorporated styrene‐butadiene‐styrene modified asphalt (SBS@MA). X‐ray photoelectron spectroscopy, atomic force microscopy, and field emission scanning electron microscopy analyses revealed that the 3D interconnected highly rough structure was constructed on the fiber surface. The surface free energy and adhesion work at the fiber and asphalt were calculated from the contact angle tests, which showed that adhesion work of the modified fibers was improved by 30% compared with the original fibers, confirming the better adhesion performance of GO‐mHNT‐PET fibers with the asphalt. The improved mechanical and viscoelastic characteristics of the modified GO‐mHNT‐PET/SBS@MA were verified by dynamic shear rheometer, and multistress creep recovery tests. At 46°C, the complex modulus of 1.5% GO‐mHNT‐PET/SBS@MA was 31.02% higher compared with that of PET/SBS@MA. This study provides a promising strategy for the preparation of PET/SBS@MA materials with excellent mechanical properties and interfacial bonding.

“…If the interface is too weak, the reinforcing effect of the fiber will not be fully developed, which will cause the fiber to peel or fall off. [10][11][12] On the contrary, if the interface is too strong, it will cause easy fracturing of fibers, forming a sudden release of load, which will weaken the interfacial toughness of the fiber-asphalt composite. Therefore, it is crucial to concomitantly improve the adhesion properties of fiber and asphalt binder, and optimize its interfacial structure to mitigate the stress concentration to enhance the road performance of fiber-modified asphalt binder.…”

The mechanical properties of fiber composites are greatly affected by the interfacial interactions between the fibers and matrix, and hence the study of interfacial properties becomes critical. This study demonstrates a simple and effective interfacial modification process using polydopamine (PDA) coating with ZnO nanorods to construct a multi‐scale bionic structure on the polyacrylonitrile (PAN) fiber, which is conducive to increasing the bonding area and enhancing the load transfer, thus boosting the mechanical properties of the modified fiber‐incorporated asphalt binder. The cone penetration test and thermogravimetric analysis show that the octopus‐inspired multiscale PAN fiber (OIM‐PAN) composite styrene butadiene styrene modified binder (SBS/MB) has better shear strength and thermal stability. Dynamic shear rheometer test shows that the deformation resistance and viscoelastic properties of the fiber composite SBS/MB are enhanced compared with SBS/MB, and the OIM‐PAN composite SBS/MB (OIM‐PAN@SBS/MB) exhibits the best deformation resistance and viscoelastic properties. Thus, it can be concluded that this interfacial modification process can significantly improve the mechanical properties of fiber–asphalt composites by introducing a third phase between the fiber and asphalt interface to achieve functionally graded material properties and enhance the load transfer between the interfaces for large‐scale applications in road engineering and construction sites.

A composite graphene oxide (GO) modifier was prepared by co‐deposition of polydopamine (PDA) and hexadecyltrimethoxysilane (HDTMS) with hydrophobic function to enhance the interfacial interaction between GO and asphalt. Dopamine as a medium enhances the adhesion of the hydrophobic functional material HDTMS on the surface of GO. And the long alkyl chains of HDTMS molecules greatly reduce the surface free energy and ensure the dispersion stability of composite GO modifier in styrene–butadiene–styrene (SBS) modified asphalt. The physical properties of modified asphalt show that the ductility, high‐temperature stability, and viscosity of asphalt can be improved by the addition of PDA/HDTMS composite GO modifiers (DH‐GO). Among them, 0.04% DH‐GO composite SBS modified asphalt binder (DH‐GO/SBSMB) has the best mechanical properties. Compared with 0.05% GO composite SBS modified asphalt binder (GO/SBSMB), the softening point of 0.04% DH‐GO/SBSMB increased by 8.3%, the penetration degree decreased by 9.7%, and the elongation increased by 18.2%. Dynamic shear rheometer (DSR), multiple stress creep recovery (MSCR) and rotational viscosity (RV) tests show that 0.04% DH‐GO/SBSMB has higher high‐temperature stability, plasticity, and viscosity than 0.05%GO/SBSMB, which meets the requirements of asphalt construction specifications.
