RUBBERIZED BITUMEN- RUBBERIZED ASPHALT- BITUMEN RUBBER

The problem of excess binder flowing off the aggregate at high temperatures was investigated specifically fur t.he use of bitumen rubber for the popcorn mix. The sample of “popcorn” rubberized asphalt was placed in the oven for two hours at 2000 C and there was no apparent flow of the binder to the bottom of the pan.

US5334641A - Rubber asphalt mix - Google Patents

A rubber modified asphalt for use as a paving compound is formed by reacting very fine ground particulate rubber with paving grade asphalt and mixing the combination at between 300 and 400 degrees F. The resulting mixture reacts fully within 25 minutes or less to form a freely pouring mixture; the reacted mixture can be held at normal asphalt working temperatures for at least 96 hours without ...
