RUBBER IN ASPHALT PAVEMENTS

THE KNOWLEDGE OF THE USE OF RUBBER AS AN ADDITIVE TO PAVING ASPHALTS HAS BEEN REVIEWED ON THE BASIS OF PUBLISHED LITERATURE FROM THE CHEMICAL POINT OF VIEW. THE LITERATURE REVEALS THAT ONLY A LIMITED NUMBER OF AVAILABLE RUBBERS HAVE BEEN EXTENSIVELY EXPLORED. ORIGINAL SUGGESTIONS WERE TO USE 7.5 TO 10 PERCENT OR MORE OF RUBBER IN ASPHALT; RECENTLY AMOUNTS AS SMALL AS 1 PERCENT AND LESS WERE FOUND TO BE EFFECTIVE AS MODIFYING AGENTS. FUTURE WORK SHOULD BE PRIMARILY CONCERNED WITH ESTABLISHING SPECIFICATIONS BASED ON NUMERICAL VALUES MEANINGFUL TO ENGINEERS AND CHEMISTS AND WITH METHODS OF RUBBERIZING WHICH CAN BE USED ROUTINELY WITHOUT INTERFERENCE WITH ESTABLISHED CONSTRUCTION PROCEDURES. /AUTHOR/
