Abstract
A two component liquid pothole filler system comprises an anionic aqueous asphalt and chloroprene emulsion liquid component, which is mixed in situ with a solid component comprising crumb rubber, and in a preferable variation, a powdered mineral material, which is preferably calcined clay powder. The solid component also preferably includes a catalytic quantity of an activator, preferably a hydrous calcium sulfate activator, or alternatively, the activator may be added to the mix at the time of in situ mixing. The mixture is poured into the pothole and in its most preferred embodiments, typically hardens in about 10 minutes. It can be driven on immediately on hardening. The liquid component is stable, and the in situ mixture is stable in use and remains stable through hardening.
