This
specification covers asphalt-rubber binder, consisting of a blend of
paving grade asphalt cements, ground recycled tire (that is, vulcanized)
rubber and other additives, as needed, for use as binder in pavement
construction.
The rubber shall be blended and interacted in the hot asphalt cement sufficiently to cause swelling of the rubber particles prior to use.
Tests shall be performed to conform with the physical requirements of the asphalt-rubber binder, in accordance with the following test methods
apparent viscosity; modified test method; penetration; softening point; resilience; flash point; thin-film oven test residue; and penetration retention.
