Using the AASHTO T 283 test, three HMA specimens were freeze–thaw


conditioned and three were unconditioned. All the specimens had a diameter


of 150 mm. Table P9.40 shows the thickness and load at failure of each specimen. Determine:


a. The tensile strength of each specimen in MPa.


b. The average tensile strength of the conditioned and unconditioned


specimens.


c. The tensile strength ratio (TSR).


d. Does the mix pass the Superpave criteria for moisture susceptibility?
