Road Pavement

With the increase of road users and also with the large construction of road pavement around the globe, accidents are a never ending issue and have been in the rise for the past decades. It has been a significant contributor towards death of humans which is alarming yearly. The interaction between these components coupled with the different types and magnitude of loadings the pavement is subjected to, results in highly complex mixture responses that require more complete understanding of asphalt mixture behavior. As a result of the lack of research conducted in developing such aggregate specifications, there are still open windows for improvement on those specifications and requirements especially designing the aggregate structure to improve mixture stability. For example, in the current Super pave system, guidance is lacking in the selection of the design aggregate structure and understanding the interaction of the aggregate structure with Civil Engineering | iii mixture design and performance. The key step to achieve that is to understand how the mechanical performance of asphalt mixtures is affected by different mixture components and properties.
