Abstract
The utilization of recycled glass in highway applications has been occurring over the past couple of decades. In recent years, the discovery of several economic and environmental benefits could increase the use of recycled glass in highway construction, making the evaluation of the engineering properties of glass and aggregate mixes necessary. The uses of recycled glass have varied widely, depending on the specific application. Crushed recycled glass, or cullet, has been used independently, and has also been blended with natural stone construction aggregate at different replacement rates. This research provides an evaluation of the potential use of glass cullet when used in combination with natural base course aggregate for roadway construction. This research studied the strength and moisture/density characteristics of different glass and aggregate blends to examine the effects of blending glass cullet into base course aggregate. Two sources of natural aggregate were tested: one being crusher run and very angular in nature; and the other being pit-run and rounded in nature.
