Method for preparing silicon—sulfur compounds and their use in bitiminous compositions |
摘要 |
A method of producing sulfur modified organosilane compounds that can be used in asphalt binders which method involves: combining together an organosilane or mixtures of organosilanes, a sulfide, a halogen acceptor and solvent to form a reaction mixture; and allowing the organosilane to react with the sulfide in the presence of a halogen acceptor to produce a sulfur modified organosilane compound. The sulfur modified organosilane compound can be introduced into a polymer modified or unmodified asphalt binder in which the sulfur modified organosilane compound reacts with components in the asphalt mixture to form a modified asphalt. The organosilanes used to produce the sulfur modified organosilanes can be from a source of waste products (such as Direct Product Residue) in which case the waste products can be reused in asphalt binders. |

1. A polymer-modified asphalt composition produced by the steps of:
a) combining together an organosilane or a mixture of organosilanes, a sulfide, a halogen acceptor, and a solvent to form a reaction mixture; b) allowing the organosilane to react with the sulfide in the presence of the halogen acceptor to produce a sulfur containing organosilane; and c) applying the sulfur containing organosilane to a polymer modified asphalt binder as an additive and/or as a crosslinking agent. |
