Properties of rubberised bitumen from reclaimed rubber

Azemi S., . Properties of rubberised bitumen from reclaimed rubber. pp. 166-182. ISSN 0127-7065

This paper discusses the properties of rubberised bitumen prepared by physical blending of bitumen with reclaimed rubber powders obtained from either rejected rubber gloves or scrap tyres. Besides reclaimed rubbers natural rubber 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 showed 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 bituminous 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.

Abstract

This paper discusses the properties of rubberised bitumen prepared by physical blending of bitumen with reclaimed rubber powders obtained from either rejected rubber gloves or scrap tyres. Besides reclaimed rubbers natural rubber 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 showed 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 bituminous 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.
