A white paper study will form the basis of a presentation at the upcoming 67th Annual Conference of the Canadian Technical Asphalt Association in November, and it’s sure to raise some eyebrows. Phil Blankenship, president of Blankenship Asphalt Tech and Training (BATT Lab) in Richmond, KY, will detail the findings of his lab’s test of an aramid-reinforced asphalt interlayer that shows great promise for performing well in Canada’s frigid climate.
“Asphalt interlayers have been a proven technology in the U.S. since 1998,” said Blankenship. “But in 2006 we made significant improvements to mix designs that now retard reflective cracking better than ever.”
He believes the time is right to move the technology north to Canada and submit it to field trials. “The high values and test temperatures we saw will blow people away.”
The BATT Lab tested a design that utilized aggregates and bitumen sourced in Canada and incorporated Surface Tech’s ARMI solution to produce an aramid reinforced composite asphalt mix. They ran several levels of performance tests, and the mix demonstrated what Blankenship termed as “incredible” crack resistance.
