Abstract The rising repair and maintenance costs of road and airstrip pavements subjected to frequent and repeated traffic loading is a major impetus for researches to delve into the use of additives and admixtures in the asphalt mixture production. The primary goal of these efforts is to improve the durability and load-bearing performance of asphalt mixtures. Due to favorable properties, such as high stiffness, all-around fracture, and high internal friction angle, crushed glass may be used as a high-potential additive for improving asphalt mixtures’ quality. Despite the many advantages of crushed glass, the inadequate adhesion between bitumen and glass particles can lead to stripping and reduced strength of glass-containing asphalt mixtures (glass-asphalt). In this study, glass particles were used, as aggregates in warm mix asphalt (WMA) mixtures. Four different amounts of zycothermTM were used in WMA mixtures to serve as bitumen modifier and anti-stripping agent. The performance properties of the pure bitumen and the zycothermTM-modified bitumen were evaluated through Scanning Electron Microscopy (SEM), Fourier Transform Infrared spectroscopy and bitumen tests. The WMA specimens and control specimens were also subjected to the modified Lottman test, resilient modulus test, and creep test. The results showed that use of zycothermTM as an anti-stripping agent considerably improves the performance properties and moisture sensitivity of glass-asphalt.
