I though you may be interested in testing inorganic SiO2 nanofibers for improving mechanical proeprties of asphalt.We have been testing SiO2 nanofibers in geopolymers and we reached very godd improvement of its mechanical properties (doubled).
We are manufacturer of this material and currently we test it in many applications. I found your blog and though you may be interested in testing and cooperation.
Please let me know

We have done some work adding our stacked-cup carbon nanotubes to cement. It greatly improves freeze/thaw and mechanical properties. Haven't done any testing in asphalt but I imagine the results would be similar.
