Properties of Asphalt Cement Used in Virginia and Their Effects on Pavement Performance

Report No: 85-R33

Published in 1985

About the report:

This is a summary report that along with the two previous reports listed as references 1 and 2 constitute the final report of the project. No unusual properties were found in any of the AC-20 asphalt cements supplied to the Virginia Department of Highways and Transportation for use in highway construction projects in 1983. This finding and the summary of effects of chemical composition on the physical properties and specifications for asphalt cements reported in reference 2 lead to the conclusion that, other than the possible addition of a requirement for a maximum ash content of 0.40 percent, no significant modification of the Department's asphalt cement specifications is needed at this time. However, from the standpoint of regional simplification of industry requirements, future consideration should be given to eliminating present differences between the Department's specification and the equivalent specification of the American Association of State Highway and Transportation Officials.
