BITUMENS WITH RUBBER ADDITION

BITUMENS FROM ASPHALTIC CRUDE OILS WERE AIR-BLOWN AT 250 DEGREES TO A SOFTENING POINT 15-20 DEGREES LOWER THAN THAT INTENDED FOR THE FINISHED PRODUCT. AFTER THE BITUMEN HAD COOLED TO 180-190 DEGREES, 5-15% ADDITIONS OF POWDERED RUBBER HAVING A GRAIN-SIZE DISTRIBUTION OF LESS THAN 1 MM WERE INTRODUCED. BLOWING WAS RECOMMENDED FOR 4-8 HOURS AT 180-190 DEGREES, THE PRODUCTS WERE USED FOR HYDROFUGE AND ANTICORROSIVE INSULATIONS, JOINTING PASTES, AND AS ADHESIVES. INVESTIGATIONS WERE CARRIED OUT FOR USING THESE PRODUCTS AS ROAD ASPHALTS, FOR THE MANUFACTURE OF ROOFING FELTS, AND AS ANTICORROSIVE PROTECTION OF THE PIPELINES. /LCPC(A)/RRL/
