A Laboratory Evaluation of Sulphur-Asphalt Paving Mixtures
This report is concerned with a laboratory program of preparing and testing Marshall specimens to evaluate the physical properties of sulphur-asphalt-sand paving material using Louisiana sand deposits and asphalt cements AC-20 and AC-40. Principal objectives of the research effort are to familiarize Department of Highway personnel with basic properties of this new paving material and verify results obtained by others through previous research evaluations. Test findings demonstrate that desirable physical properties based on the Marshall method of mix design can be obtained with various combinations of sulphur, asphalt and sand mixed in a manner similar to asphaltic concrete. The material exhibited somewhat higher Marshall stabilities with a slightly greater sensitivity to water action, based on Marshall immersion tests, than conventional asphaltic concrete mixtures.
