    Laboratory tests conducted to determine the effects of substituting fifteen percent crushed glass for a portion of the fine aggregate in an asphalt paving mixture indicate that the mixtures containing either coarse or fine crushed glass had lower Marshall stabilities and dry tensile strengths compared to a control mixture. The percentage of retained tensile strengths (TSR's) indicated that the mixture containing fine crushed glass was prone to moisture damage. The mixture containing coarser crushed glass compared favorably with the control mixture with respect to TSR. The liquid antistripping agent was apparently ineffective in mitigating stripping in the tensile strength tests. Conversely, boil tests with only the glass indicated that the coarse glass stripped more than the fine glass, and that some improvement was affected by the antistripping additive.
