Abstract:
The performance of limestone warm mix asphalt mixtures using Sasobit over
controlmixtureswas investigated. The Superpavemixture design method was
used to prepare control and Sasobit-modifiedmixtures. The indirect tensile and
dynamic creep tests were used for fatigue and rutting evaluation, respectively.
Themain findings of this research were the noticed lower accumulated strains
and resilient modulus for Sasobit-modified mixtures over control mixtures in
rutting performance testing. On the other hand, higher creep stiffness values
in fatigue testing for Sasobit-modified mixtures were observed over control
mixtures for deviator loads that ranges from 1 to 2 KN. Moreover, better
fatigue resistance at lower temperatures was also observed for both control
and Sasobit-modified mixtures.
