Benefits: Rubberized Asphalt Concrete (RAC

Generally RAC-G hot mixes cost about 20-25 percent more than conventional mixes, although this may vary with job size. Added material costs (rubber, asphalt) plus mobilization and set up of the asphalt rubber binder production equipment increases initial unit costs.
