Studying the Effect of Adding Polymeric Wastes on the Rheological Properties of Asphalt.

Abstract

This research aims to prepare different types of asphalt materials with good rheological specifications compared to unmodified asphalt materials. Three types of polymeric materials used to enhance characteristics of Doura asphalt, namely PS, PFR, PP, to study effect of these polymers on rheological specifications of resulting asphalt systems and compare them with each other and with international, local specifications. To determine its suitability for use in a specific field and not another. Waste polymeric materials used instead of virgin materials for purpose of reducing environmental pollution, reducing costs of modification. The treatment was carried out using two methods: physical treatment based on mixing thermally broken down polymeric materials with asphalt. Chemical treatment depends on carrying out a catalytic chemical reaction using 2%anhydrous ferric chloride and 1%S. From the two methods, asphalt samples were obtained that could be used in field of producing of mastic which is used as a water proofing material, based on measurements that were made (softening point, penetration, ductility, PI, %asphaltene).
