Abstract
A bitumen-rubber composition contain 0.5-10% by weight of unvulcanized natural or synthetic rubber having a gel content of less than 5% and preferably less than 3%. The bituminous material may be natural asphalts, coal tars, or petroleum pitches, which may be in the form of an aqueous emulsion, and the rubber may be in the form of latex, e.g. natural latex or a latex of butadiene-styrene, polybutadiene, butadiene-acrylonitrile, or polyisoprene, or powder produced by precipitation with clay, diatomaceous earth, powdered coal, or a powdered bitumen having a softening point above 200 DEG F.
