Tested by Bowser Morner Labs.

• 29% improved penetration value of the treated binder
• 45% improved viscosity value of the treated binder
• 17% improved Marshal stability value of the compacted mix

"This series of tests demonstrated that [Biorestor] reduced the effects of oxidation and age hardening of asphalt binders by reducing the rate of hardening of the binder resulting in an extended life of a pavement."

"We are of the opinion that these results reinforce our belief that some seal coat materials [like Biorestor] that soften the binder portion of an asphalt pavement will extend the life of that pavement indefinitely if used every four or five years as long as the pavement does not fail structurally."
