Summary:
Numerous noise level studies in the U.S. and abroad prove use of Asphalt-Rubber as the binder in Asphalt-Rubber hot
mix reduces traffic noise levels dramatically.  
This phenomenon was first noted in Brussels, Belgium, in 1981, in an Asphalt-Rubber hot mix called “Drainasphalt.”  
Since then, there have been noise studies conducted in three continents on Asphalt-Rubber hot mix pavements.  
Results of these evaluations are documented in technical papers published and are briefly reported here, and
summarized in the conclusion.
