Study of cement pastes rheological behavior using dynamic shear rheometer [PDF]

open access: yesRevista IBRACON de Estruturas e Materiais, 2014
Concrete, in its fresh state, has flow characteristics that are crucial to its proper launch and densification. These characteristics are usually measured through empirical testing as the slump test, but this test does not quantify completely the ...

Rheological Characterization of Asphalt Fine Aggregate Matrix Using Dynamic Shear Rheometer. [PDF]

open access: yesPolymers (Basel), 2019
Asphalt fine aggregate matrix (FAM) is a predominant component directly related to field performances of hot asphalt mix (HMA), it is necessary to investigate material properties of FAM. Prior to preparing FAM specimens, the asphalt content was calculated by keeping the filler–bitumen (FB) ratio the same as in the corresponding HMA.

Effect of Various Dynamic Shear Rheometer Testing Methods on the Measured Rheological Properties of Bitumen. [PDF]

open access: yesMaterials (Basel), 2023
A 23 factorial design experiment was conducted to study the influence of pre-heating temperature (HT) for manufacturing sample, bonding temperature (BT) onto rheometer, and trimming state (Trim) of the sample on complex shear modulus (G*) and phase angle (δ) using a dynamic shear rheometer on unmodified bitumen of types 50/70, 70/100, and two 160/220 ...

Asphalt Binder Testing at Low Temperature: Three-Point Bending Beam Test in Dynamic Shear Rheometer

open access: yesFrontiers in Materials, 2022
A novel Three-Point Bending Beam Test (3-PBT) using a Dynamic Shear Rheometer (DSR) with linear drive motor is introduced for testing asphalt binder at low temperature conditions. This 3-PBT in DSR can be used as surrogate for Bending Beam Rheometer (BBR)
