The Illinois Tollway used Sripath’s asphalt rejuvenator, ReLIXER, to test the performance of a high-traffic roadway prone to extreme weather conditions. The goal was to incorporate a minimum of 40% Reclaimed Asphalt Pavement in their balanced mix design while achieving key performance specifications.
When evaluating sample performance, Illinois Tollway used several different tests. The Disc-Shaped Compaction, or DCT, Test explored fracture toughness and demonstrated that mixes dosed with 2% ReLIXER exceeded the target specification. The Hamburg Wheel Tracking Test for rutting showed acceptable rut resistance. Notably, the amount of virgin binder needed in the mix dosed with ReLIXER was also lower than the control.
