PURPOSES : The purpose of this study was to evaluate newly developed Guss mastic asphalt with polymer modifier as a elastomer and a plastomer in to polymer content.
METHODS : As polymer modifiers, 10%, 20% of elastomer and 10%, 20% of plastomer, and 10% of elastomer and 10% of plastomer are all added to the binder, and the physical properties of the Guss mastic asphalt mixture with these binders are changed. The properties of mixtures with workability, penetration depth and dynamic stability were compared with the existing Guss mastic asphalt mixture.
RESULTS : When using the elastomer and the plastomer, the dynamic stability of the Guss mastic asphalt mixture was improved compared to the conventional asphalt mixture, and when the amount of the elastomer was 20%, the workability was reduced. In addition, when 10% of the elastomer and 10% of the plastomer were used, the workability was not significantly deteriorated and the dynamic stability was increased.
CONCLUSIONS : In order to improve the dynamic stability of the Guss mastic asphalt mixture using the polymer-modified binder, it is effective to use an elastomer and a plaststomer.
