Roadway maintenance and repair, and, in particular, to enhanced crack filler materials, systems, and methods for filling and repairing cracks in asphalt surfaces, such as asphalt roadways. The enhanced crack filler material includes crack filler and a silane additive. The silane additive includes organosilane, benzyl alcohol, and ethylene glycol. The crack filler can be a conventional crack filler material that, when combined with the silane additive, provide an enhanced crack filling material that enables improved crack filling operations, cleaning, and repair durability beyond conventional crack filler materials alone.

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.

Reinforcing fibers, such as aromatic polyamide (aramid) fibers, are treated by coating with or embedding in a binder such as a Fischer-Tropsch wax. The treated fibers are divided into suitably-sized units, which are added to bitumen, aggregate and other ingredients in an asphalt cement concrete mix. The units shed fibers into the mix during the manufacturing process so that the fibers are distributed fairly evenly throughout the asphalt mixture. The binder may also impart beneficial qualities to the finished asphalt concrete.

A glass mat includes an assembly of glass fibers, a binder composition and an asphaltic coating. The binder composition includes an organic resin and an adhesion promoter. The glass mat has an at least 2% increase in tear strength as measured using the methods specified in ASTM D3462, compared to an asphaltic coated glass mat having a binder composition without the adhesion promoter. Further provided is an asphalt roofing product including the glass mat and a method of increasing tear strength in an asphalt roofing product.
