Polymers Effectiveness on Properties of Asphalt Concrete Mixtures

Abstract

The process of improving the resistance of asphalt roads to the impact of weather in the hot regions is a real challenge for those in charge of industry methods because of their economic implications are important. The use of polymeric materials of the active substances in order to improve the resistance of asphalt roads to the impact of weather, resulting in the longevity of the road. For this, the main objective of this study is to try to determine the criteria and variables related to the ability of asphalt mixtures using the improved polymeric materials to resist the influence of weather factors, which helps to identify the most appropriate materials can be added to the roads in these regions, such as Iraq. We selected Asphalt of " BIJI Refinery " "type 40-50" with four exhaust polymers “ polystyrene - polyvinyl chloride – cellulose acetate and Polyethylene Terephthalate " to note the difference in the results on the standards tests used, such as penetration ; softening point and ductility after assessing the melting point for each subject polymer additives and therefore compare the results with the asphalt before posting. From the results proved the possibility of using some of these polymers as a benefactresses of asphalt mixtures, as shown in the search pages
