A comprehensive review using natural rubber in the modification of bitumen used for road
construction is presented in this paper. The sources, types and properties of natural rubber …

In recent times both natural and synthetic rubber were blended with bitumen with the hope of
producing a more durable hot mix asphalt. Although the application of natural rubber (NR) in …

The purpose of this study was to improve the problems of inadequate storage stability and
insufficient high-temperature rutting resistance of crumb rubber-modified asphalt (CRMA) by …

Natural rubber (NR) in the form of “cup lump” is used to significantly enhance the thermal
stability and elasticity of bitumen. Despite these benefits, the paving industry has raised …

Despite the several benefits of modifying bitumen with polymer; it is increasingly becoming
difficult to ignore concerns about its high energy consumption and fume emissions during …

Polymer modified bitumen (PMB) has been used for many years to improve the performance
of asphalt concretes against premature pavement defects. In this research, modified …

The use of cup lump rubber as an additive in asphalt binder has recently become the main
interest of the paving industry. The innovation helps to increase the natural rubber …

One of the major obstacles to Nigeria's techno-economic development has been a lack of
good road infrastructure. Despite a large deposit of natural bitumen in the form of semi-liquid …

Pure bitumen is not suitable for heavy traffic loads; hence modifiers are used to improve the
bitumen performance. Recently, cup lump rubber (CLR) has become a preferred modifier …

Modification of asphalt binder is a must to enhance the performance of asphalt binder. The
objectives of this study are to develop an extensional deformation test method using a …
