Given the application characteristics and shortcomings of basalt fiber in road engineering, improvements to its reinforcing effect in asphalt mixture, such as reinforcing, toughening, and bridging, are needed. A silane-coupling agent (ammonia propyl triethoxysilane, or KH550) is used to pretreat and modify the surface of basalt fiber.
