Popis:	This paper provides a performance comparison of mechanistic laboratory and field rutting performance of four asphalt concrete mixes constructed in 1996 at a Strategic Highway Research Program SPS-9A test site located in Saskatchewan. The asphalt mixes included two Saskatchewan Type 70 Marshall mixes and two coarse graded Superpave™ mixes and employed 150–200A and 200–300A penetration grade asphalt cement binders. The triaxial frequency sweep characterization determined that the Superpave™ mix yielded improved mechanistic structural constitutive properties when compared to the Saskatchewan Type 70 mix. In addition, improved mechanistic structural properties were observed with the mixes employing 150–200A (PG 58-28) asphalt binder relative to the 200–300A (PG 52-34) asphalt binder, particularly the Saskatchewan Type 70 mix. The 10-year rutting performance of the Radisson SPS-9A test site was evaluated and the field rutting results concurred with the triaxial frequency sweep test results. The triaxial frequency sweep characterization employed in this study appears to adequately rank asphalt mixes with respect to field rutting performance.
