Feasibility of Using Recycled Glass in Asphalt

Report No: 90-R3

Published in 1990

About the report:

This report was written in response to HJR 301, which "requests the VDOT to conduct a study of the feasibility of using recycled glass as supplemental aggregates in asphalt." The laboratory study did not indicate that there would be any adverse affects from the use of small percentages of glass (5 to 15 percent) under controlled gradation conditions. However, the use of recycled glass in both highway embankments an in unbound aggregate base materials would be preferable to its use in asphalt because of the propensity of the asphalt coating to be separated from the glass in the presence of moisture. The use of recycled glass in any highway construction will be strongly influenced by the cost of crushing and hauling it.
