Newer technologies such as warm mix asphalt (WMA) and reclaimed pavement (RAP) have gained international approval been considered appropriate solutions that support the sustainability goals of highway sector. However, both present some shortcomings. The lower mixing compaction temperatures WMA reduce binder aging bond between aggregates coating binder, thus resulting in less rutting resistance ...

Steel slag is a by-product obtained through the separation of molten steel from impurities in steel-making furnaces. It can be produced by different types furnaces (blast, basic oxygen, electric arc, ladle furnaces). The reuse metallurgical slags road pavements pursue aims recycling and environmental sustainability. Based on extensive literature, paper presents state-of-the-art review concernin...

The majority of recent research in has been focused on the introduction, development, and evaluation performance-based specifications for design asphalt concrete mixtures. In Caribbean, most laboratories only use Volumetric Marshall Mix methodology. Road designers, engineers, consultants, contractors have all highlighted many shortcomings inadequacies volumetric mix selection process. consensus...

The performance of asphalt binders at high and low temperatures has an important role on the rutting and crackingresistance of asphalt pavements. Crumb Rubber Modified (CRM) is one of the asphalt modifiers that improves asphaltphysical and mechanical properties and helps reducing environmental pollution. In this research, three unmodifiedand six CRM modified binders were teste...
