Although the use of waxes in bitumen modification is not new, the effect of waxes on bitumen and bituminous mixture performance is still a complex subject of debate. This study was carried out to address this complexity and to comprehensively demonstrate the effect of wax-based additives on bitumen and bituminous mixtures. In this context, the systematic quantitative literature review (SQLR) method, which is more objective than the verbal approach, was adopted, and the results were systematically compared based on the numerical data obtained from the studies in the literature. The effect of waxes on the physical, rheological, chemical, and thermal properties of bitumen and the performance characteristics of bituminous mixtures have been evaluated in detail.
