Original Abstract

The issue of reusing waste materials is becoming very current and also includes reusing used tires. One of the possibilities is using these tires for the production of crumb rubber, which is added as a modifying agent into paving bitumens. The paper compares properties of this special type of asphalt binder with properties of conventional binders. In order to test the rheological properties, needle penetration, softening point, dynamic viscosity, resilience and elastic recovery tests were performed. Emphasis was put on description of rheological behavior determined using dynamic shear rheometer with the effects of ageing assessed using RTFOT method. The results show that using crumb rubber as an additive to asphalt binders seems as a successful example of a technology aimed at maintaining sustainable development by reusing waste material in the form of used tires.

Keywords
