Volumetrics in Asphalt Mixtures

2019-3-18  Volumetrics in Asphalt Mixtures The question often arises about controlling asphalt mixtures during the mixture design process and during production. Many people who are reviewing these numbers have a complete understanding of how the numbers effect the mixture, while some have little or no experience with these numbers. This will try to explain

Determination of volumetric criteria for designing hard

2021-4-5  Hard HMAs refer to the mixtures designed using hard asphalt binder whose penetration is less than the conventional one (70#). Increasing asphalt content is regarded to be an effective way to design hard HMAs and keeps them away from thermal cracking problem. Therefore, this research explored the suitable volumetric criteria for designing hard HMAs.

Development of a Performance-Volumetric Relationship

2019-5-9  For this study, three asphalt mixtures were first designed to incorporate systematic changes in volumetric conditions, then fatigue cracking and rutting performance tests were conducted at each condition. Statistical analyses of the results suggest that a first-order (linear) model and power model would be an appropriate form of the PVR function.
