Abstract
A method of preparing an asphalt emulsion-rubber paving composition comprises combining an aqueous asphalt emulsion, water, latex rubber, minus 40 size rubber particles, and a thickening agent, mixing said materials at substantially ambient temperature to form a substantially homogeneous liquid composition, adding to said liquid composition between about 5 and about 15 pounds of aggregate per gallon of said gallon, and mixing the components at substantially ambient temperature to form such paving composition.
Claims6
A method of preparing an improved asphalt emulsion-rubber paving composition comprising:
- preparing a liquid composition by combining an aqueous asphalt emulsion, water, a thickening agent, latex rubber, and rubber particles of a size passing through a 40 mesh U.S. series sieve, wherein the latex rubber:rubber particle ratio is between about 1:3 and 1:5, by weight, respectively, mixing said components at substantially ambient temperature to form a substantially homogeneous liquid composition, adding to said liquid composition between about 5 and about 15 pounds of aggregate per gallon of said liquid composition, and mixing the components at substantially ambient temperature to form said paving composition.
