Tertiary nitrogen heterocyclic material to reduce moisture-induced damage in asphalt-aggregate mixtures
Patent
·
OSTI ID:864181
- Laramie, WY
Asphalt-aggregate roads crack when subjected to freezing and thawing cycles. Herein, the useful life of asphalts are substantially improved by a minor amount of a moisture damage inhibiting agent selected from compounds having a pyridine moiety, including acid salts of such compounds. A shale oil fraction may serve as the source of the improving agent and may simply be blended with conventional petroleum asphalts.
