Evaluation of Rational Medicine Use based on WHO Core Drug Use Indicators in Public Hospitals in West Shoa Zone, Oromia, Ethiopia

Abstract

This research aims to assess and then compare the high-temperature rendering of tafpack super, tire rubber, and Polypropylene. Dynamic shear rheometer experiment out righted to mensuration linear viscoelasticity areas of the modified bitumen at 58-88°C. Additionally, the modified asphalt mixture's rutting deepness is measured in millimeters using the wheel tracking test. Finally, the rheological features of the improved asphalt were contrasted together with each other as well as with the perspicuous asphalt. Conclusions manifested that the tire rubber modifier has more excellent characteristics in high temperatures and less rutting depth than poth polypropylene as well tafpack super.
