Abstract

"The problem of solid waste disposal increases each year, with the annual growth in quantity of solid waste making the present means of disposal even more inadequate. Recycling of solid waste materials is an increasingly popular approach to the disposal problem. The glass component of solid waste is a very promising candidate for recycling, and this investigation studies the possibility of using waste glass as an aggregate for bituminous concrete mixtures. Objectives of this research were to determine whether a glass-asphalt mixture could be designed to meet the Marshall design criteria specified by The Asphalt Institute, to study the amount of degradation occurring in a glass-asphalt mixture, and to find whether a glass-asphalt mixture will be resistant to the action of water. Material for testing was obtained by crushing waste glass and sieving it into various size fractions which were combined to obtain the gradations desired. Tests were conducted on the crushed glass to determine various physical properties. Marshall tests were run on specimens at different asphalt contents to see if the Marshall design criteria could be met for the gradation used. Glass was extracted from some of the specimens tested, and sieve analyses of the extracted glass were used to determine the amount of degradation occurring in the glass-asphalt mixtures. Statistical analyses were made to evaluate the significance of the Marshall test results. Static stripping tests and immersion-compression tests were used to determine the water resistance of the mixtures. It is possible to design glass-asphalt mixtures which meet the Marshall design criteria. Extraction data indicates that some degradation does occur during laboratory mixing, compacting, and testing. Mixtures consisting only of glass and asphalt cement show no water resistance; however, the addition of a commercial anti-stripping agent improves water resistance without completely eliminating stripping. Hydrated lime gives excellent water resistance and completely eliminates visible stripping"--Abstract, page i-ii.
