Abstract

The research investigates the properties of bitumen modified with used tyre. Basic tests such as penetration, softening point, viscosity , flash and fire point and ductility test were carried out by using shredded waste tyre which varied from 0% to 20% by weight of 60/70 penetration grade bitumen at 1600C using dry mix method. Penetration value decreased with  addition of 20% tyre while increase in  softening point, viscosity, flash and fire point were obtained with the corresponding values of 80.90C, 250.96 sec and 189/280.120C respectively. However, the values obtained exceeded the minimum values specified by American Standard for Testing and Materials (ASTM). The ductility value obtained with the addition of 6% and 14% tyre are 44.64cm and 40.6cm respectively. Thus, addition of 6% tyre content to bitumen is however suggested for best ductility value.
