Effect of Hot Glue Additive on the Rheological Properties of Asphalt Cement and Mixtures Performance

In general, the physical and rheological properties of asphalt binder are directly affecting resistance mix to permanent deformation (rutting), water damage, thermal cracking. The degradation in these leads severe distresses that appear pavement and, consequently, make repair maintenance very expensive. Since modified-asphalt cement may help minimize such aforementioned distresses, this research is established for purpose. It aims investigate with silicone, dense silicone rubber, ethylene propylene diene monomer rubber. Five contents each type hot glue investigated; 0.4, 0.8, 1.2, 1.6, 2% weight. Conventional tests as penetration, softening point, dynamic viscosity, ductility conducted evaluate glue-modified properties. Moreover, Marshall indirect tensile strength examine effect on performance mixtures at concentrations 0.8 1.6% results show an increase hardness consistency, a reduction temperature susceptibility cement. These features lead better stability ratio, compared standard mixture.
