Claim 1
Independent Claim

A composition for use as a highway joint sealing material, said composition having a recovery of at least 60% for the resilience test of ASTM D 3405-75-T and having at least five cycles for the bond test of Federal Specification SS-S-164, said composition comprising the reaction product of a mixture consisting essentially of asphalt flux, styrene and a vulcanizable styrene-butadiene rubber, said rubber being a copolymer of about 25% by weight styrene and about 75% by weight butadiene, and said mixture being about 69.4% to about 73.8% asphalt flux, about 10.9% to about 12.6% styrene and about 14.8% to about 18.3% of said rubber, based on the weight of flux, styrene and said rubber.
