Test methods
The technical specifications reference a new test method ATM 058 and updated test methods ATM 191, ATM 192 and ATM 250.
ATM 058 has been developed for assessing aggregate shape as a ratio of Average Greatest Dimension to Average Least Dimension.
ATM 191, ATM 192 and ATM 250 set out procedures for extracting bituminous binders from bituminous mixtures, the determination of viscosity of binders recovered from RAP source materials, and the determination of the surface texture depth of road surfaces, by the sand patch technique.
