Reclaimed rubber was obtained by using waste truck or bus tire rubber powder with the reaction of cuprous chloride-ethanolamine system.
Rubber compound having a different ratio of reclaimed rubber to rubber powder was blended with asphalt cement to get a variety of modified rubber asphalt.
In general, increasing mixed rubber, at a specified temperature, would increase the softening point, viscosity and penetration of modified rubber asphalt. But at a higher blending temperature, there was a decreasing of penetration for the reason of more oxidation.
With the same consistency of mixed rubber blended, increasing the amount of reclaimed rubber or at a higher blending temperature, generally would increase softening point and viscosity, but would decrease penetration.
Above 10% of mixed rubber blended and the more containing of reclaimed rubber, the more access to maintain the balance relation of anti-flow, anti-abrasion and anti-brittiness on pavement road.
