Potential Use of Tar Sand Bitumen as Paving Asphalt
The properties of several tar sand asphalts prepared in past studies by several different investigators were compared with each other and with the properties of petroleum asphalts. These results were reviewed and discussed with regard to the potential use of tar sand bitumen in pavement applications. The data show that tar sand bitumen has good potential for use in highway pavements that meet today's performance specifications. No deficiencies in the tar sand asphalts were found that would be expected to seriously affect performance. On the other hand, the data indicate that some tar sand asphalts may have superior aging characteristics, being relatively resistant to oxidative age hardening compared with typical petroleum asphalts. Asphalt-aggregate mixtures prepared using two tar sand asphalts also showed acceptable strength properties and excellent resistance to moisture-induced damage. (ERA citation 12:028344)
