INVESTIGATION OF THE MECHANICAL PERFORMANCE OF STONE MASTIC ASPHALT MIXTURES MODIFIED BY RECYCLED WASTE POLYMERS

The usage of polymer-modified asphalt binders has increased as a result the significant increase in number conventional cars operating on Iraqi roads recent years. This resulted strains being placed pavement structures and materials. Global exploration focused development stabilizing Stone Mastic Asphalt mixtures for improved behavior. Numerous effective efforts were made to stabilize stone mastic mixes with polymers fibers. Iraq produces considerable amount waste polymer materials each year. Usually, they are sent landfills disposal. These wastes dumped, occupying sizable portion landfill space creating various serious environmental issues. study focuses how additions, such recycled plastic bottles, shopping boxes, tire crumb rubber, affect mechanical performance durability mixtures. attributes assessed. It is evident from findings that drain-down amounts within permissible requirement range. also showed indirect tensile strength, Marshall Stability, moisture damage resistance, resistance permanent deformation have all use components. combinations most resistant rutting, according results repeated load axial creep tests. may new options employ volumes becoming accessible recycling polymers.
