The one of various pavement distresses in Korea is the pothole. Most of these surfaces distresses are related with traffic loading and environmental condition. The water strongly affects the asphalt distress. To reduce infiltrated water into asphalt pavement structure, the waterproofing asphalt layer is necessary. Currently, Guss asphalt mixture was most used for impermeable asphalt mixture, however, the Guss asphalt mixture was expansive and required a special guess asphalt binder and equipments. In this study, the impermeable asphalt mixture using a waste glass wool was investigated for alternative waterproof material. It is less expensive than the Guss asphalt mixture. The research team was evaluated the effect of the waste glass wool in the asphalt mixture properties by using the Marshall Stability Test, Indirect Tensile Strength Test, Hamburg Wheel Tracking Test, etc. The Marshall stability and indirect tensile strength of the asphalt mixture containing waste glass wool were superior to the reference mixtures. It means that the waste glass wool is able to use impermeable asphalt mixture to improve asphalt performance based on this study.
