Abstract
A method of preparing an asphalt emulsion composition comprises mixing an aqueous asphalt emulsion, water, latex rubber, and a solids mix composition comprising reclaimed rubber particles passing through a 40 mesh U.S. series sieve and one or more solid addends selected from the group consisting of a rheological agent, gilsonite, carbon black, surface active clay and polymer fibers, and mixtures thereof and wherein the ratio of latex rubber:rubber particles is between about 1:1 and about 1:10, by weight, respectively, and mixing the components at substantially ambient temperature.

A method of preparing an improved asphalt emulsion paving composition comprising:
- mixing aggregate, an aqueous asphalt emulsion, water, polymer latex, reclaimed rubber particles passing through a 20 mesh U.S. series sieve and one or more solid addends selected from the group consisting of a rheological agent, gilsonite, carbon black, surface active clay and polymer fibers, and mixtures thereof wherein the ratio of polymer latex:rubber particles is between about 1:1 and about 1:10, by weight, respectively, and mixing the components at substantially ambient temperature.
An asphalt emulsion composition prepared by mixing, at substantially ambient temperature:
- a major amount of an aqueous asphalt emulsion, polymer latex, rubber particles passing a 40 mesh U.S. series sieve and natural, synthetic or semisynthetic polymer fibers wherein the ratio of polymer latex:rubber particles is between about 1:1 and 1:10, by weight, respectively.
A solids mix composition comprising reclaimed rubber particles, at least a major amount of which pass a #20 U.S. series mesh, and latex rubber, wherein the ratio of said latex rubber:rubber particles is between about 1:2 and about 1:5, by weight, respectively, and one or more solid components selected from the group consisting of a rheological agent, gilsonite, carbon black, natural synthetic or semisynthetic fibers, and a surface active clay.
