N2  - This paper discusses the properties of rubberized bitumen prepared by physical blending f bitumen with reclaimed rubber powders obtained from either rejected rubber gloves or scrap tyres. Besides reclaimed rubbers, natural ruber latex and synthetic polymer such as ethylene methyl acrylate were also used to prepare the rubberised bitumen. Properties such as penetration number, softening point, work done to break and tenacity were measured; results showeed that the properties improved with the addition of rubber. The softening point, tenacity and energy to break increased progressively while penetration number decreased with increasing rubber content. Rubberised bitumen prepared by using glove crumbs produced overall better properties than that using tyre shavings. The properties of rubberised bitumenous mixes were also evaluated and compared with those of ordinary bituminous mixes. The results showed that rubberised bituminous mixes produced higher resistance to permanent deformation and dynamic cracking compared with ordinary bituminous mixes
