Disclosed is a glass fiber-reinforced composite material, an asphalt mixture using the same, and a manufacturing method thereof, the method comprising manufacturing, as a mixed structure, a bundle type fiber reinforcing material by coating with a polypropylene resin; a scrap reinforcing material having pellet or particle shaped glass fiber scrap, the glass fiber scrap having economical and outstanding physical properties and several strands of glass fiber; and adding the same to a hot-mix asphalt mixture, thereby capable of being injected at a plant construction site in a simple manner and improving the performance of the asphalt by preventing the phenomenon of the fiber becoming entangled within the produced hot asphalt mixture.

According to one embodiment, a gypsum-based slurry composition is disclosed. The gypsum-based slurry composition can include a precursor stucco component, a precursor reinforcement component comprising glass fibers coated with a glass fiber coating. The glass fiber coating can comprise PVOH, PVAC, hydrophilic silane, or a combination thereof.

Various embodiments of the present invention provide sizing compositions, fiber glass strands, cement boards, and other products incorporating fiber glass. In some embodiments, a sizing composition of the present invention comprises a starch, a nonionic lubricant, a silane comprising at least one amine and at least one aryl or arylene group, and an aminofunctional oligomeric siloxane.

The invention relates to a glass-fiber textile structure, characterized in that it has a parylene (poly(para-xylylene)) coating with a thickness of between 5 m and 30 m, preferably between 6 m and 25 m, in particular between 7 and 20 m. The invention also relates to a method for reinforcing a solid material, which comprises introducing such a textile structure having a parylene coating into a fluid base material, preferably a base material comprising water and a hydraulic binder, and curing the base material.
