The study presented herein provides important results on the necessity of regulating concrete road mix design specifications according to regions and climates to reduce the temperature gradient values which are very important in concrete road design.
Concrete road mix design specifications need to be regulated according to regions and climates to reduce the temperature gradient values and waste glass, which is needed to be used in sustainability, can also be used in concrete pavement mixture design in this purpose.
It was concluded that when an adequate size reduction and separation procedure is used, mixtures with better quality can be obtained since the mix design specifications can be achieved more easily and the binder of the final mixture is less aged by the high temperatures.
The mechanical properties of recycled aggregate concrete (RAC) may be inferior to those of conventional concrete that contain natural aggregate, but they are sufficient nonetheless for some practical applications in terms of mix design, design specifications, etc., based on results found in the literature.
Some of the key processing steps and parameters to consider in the validation protocol are: Solutions Manufacture (drug-containing or drug-free) mixing equipment design specifications, order of addition, mixing speed, mixing time open or closed vessel During development and scale up it may be beneficial to consider component changes either by the developer or raw material suppliers.
The results presented are part of a study for the New Jersey Department of Transportation NJDOTto to develop and implement High-Performance Concrete (HPC) mix design and technical specifications for transportation structures.
Selection of aggregate gradation and binder content for asphalt mix design, which comply with specification requirements, is a lengthy trial and error procedure.
Therefore, serious plans should be set up in Jordan to shift from the presently used Marshall mix design procedure to SUPERPAVE mixture specifications.
Future research should, therefore, focus on defining particular specifications for mix design and control for AR PFC and PG-PFC mixtures.
The results may also be useful for optimizing the laboratory mix design process by directly relating certain Superpave specification parameters to mixture rutting resistance.
