Rubberized Emulsion Aggregate Slurry: Rubberized Emulsion Aggregate Slurry (REAS) is produced when crumb rubber is blended into asphalt emulsion at ambient temperature and used as a slurry to repair roadways. Although the cost of REAS is higher than for conventional slurry, the advantages include an approximate 50% increase in longevity, long lasting color contrast for striping and marking, and high skid-resistance. In addition, REAS uses more than seventy-eight waste tires per lane mile, thereby diverting waste
tires from traditional disposal. To ensure the success of the Program and stimulate the market for waste tires through the slurry seal projects, the County Department of Public Works, in conjunction with Petrochem Marketing, Inc., developed specifications and testing criteria for the REAS material.

R.E.A.S Continued.
As a result of the successful use of REAS, these specifications and testing criteria have been incorporated into the 1998 supplement of the Standard Specifications for Public Works Construction, commonly referred to as the
"Green Book".
To date, more than 200 cities, counties, and agencies in the State have adopted the Green Book as their standard. The County also aggressively identifies and rewards contracts for the use of REAS on many road projects, funding millions of dollars in projects each fiscal year.
