Shingle material can appear as an excess usage due to defective production problems or at the end of their
service life. Especially the reuse of shingle materials in bitumen has brought a different approach in terms of
sustainability. In this study, the utilization of production shingle waste material in asphalt pavement were
investigated. Mechanical properties of hot mix and warm mix asphalt samples involving different amount of
production shingle waste (1-6% by weight of the aggregate) were evaluated. Following the determination of
optimum rate of shingle waste bitumen content is reduced to decrease both hazardous effects of bitumen and
production cost. Marshall Mix Design criteria was employed on determination of maximum reduction on bitumen
content and the amount of shingle utilization within the asphalt pavement. As a final analysis, indirect tensile tests
were performed on the specimens prepared with determined bitumen content and shingle waste. As a result, it is
concluded that, utilization of waste shingles within the asphalt mixture not only benefits the environment and cost
but also improves Marshall stability and Marshall quotient of the mixtures.
