Mechanistic and Volumetric Properties of Asphalt

2020-1-28  This research examines how the addition of RAP changes the volumetric and mechanistic properties of asphalt mixtures. A Superpave 19 mm mixture containing 0% RAP was used as the control for evaluating properties of mixes containing 15%, 25%, and 40% RAP. Two types of RAP were evaluated: a processed RAP and an unprocessed RAP (grindings). Testing included dynamic

Influence of volumetric property on mechanical

2017-3-15  VV is the most important volumetric property of asphalt mixtures that influences mechanical properties [4]. The strength, high-temperature stability, durability, and water permeability of asphalt mixtures strongly depend on their VV values being neither too high nor too low [5], [6].

Volumetric Properties of Mixtures and Solutions ...

While thermal properties are related to derivatives of ther- dynamic functions with respect to temperature, the volumetric properties determine changes of ther- dynamic functions with pressure. Volumetric properties of pure liquids and liquid mixtures and solutions are important from the theoretical point of view because they reflect the structure and the intermolecular interactions in the system.
