Performances Evaluation Of Cecabase® Rt In Warm Mix Asphalt Technology, Shu Wei Goh, Mohd Rosli Mohd Hasan, Zhanping You
Performances Evaluation Of Cecabase® Rt In Warm Mix Asphalt Technology, Shu Wei Goh, Mohd Rosli Mohd Hasan, Zhanping You
Michigan Tech Publications
The purpose of this study was to evaluate the performance of warm mix asphalt (WMA) mixtures containing different percentages of Cecabase® RT using dynamic modulus (|E*|), tensile strength ratio (TSR), four point beam fatigue, flow number and asphalt pavement analyzer (APA) rutting tests. In this study, 0.2%, 0.35% and 0.5% Cecabase® RT were incorporated in the 5E3 Superpave mixtures prepared at three different temperatures, 100 °C, 115 °C and 130 °C. A Hot Mix Asphalt (HMA) mixture was used as the control mixture. All the mixture samples were prepared using PG 58-34 binder and compacted at 86 gyrations under different …

The Main Difference between Conventional Vibrated Concrete (CVC) and Self-Compacting Concrete (SCC) is Observed in the Fresh State, as SCC Has a Significantly Lower Yield Stress. on the Other Hand, the Placement of SCC by Means of Pumping is Done with the Same Equipment and Following the Same Practical Guidelines Developed for CVC. It Can Be Questioned Whether the Flow Behavior in Pipes of SCC is Different and Whether the Developed Practical Guidelines Can Still Be Applied. This Paper Describes the Results of Full-Scale Pumping Tests Carried Out on Several SCC Mixtures. It Shows Primarily that the Slump or Yield …
Extension Of The Reiner-Riwlin Equation To Determine Modified Bingham Parameters Measured In Coaxial Cylinders Rheometers, Dimitri Feys, Jon E. Wallevik, Ammar Yahia, Kamal H. Khayat, Olafur H. Wallevik

The Determination of the Exact Rheological Properties, in Fundamental Units, of Cementitious Materials Has Become Gradually a Necessary Step in the Domain of Concrete Science. Several Types of Rheometers and their Corresponding Transformation Equations Are Described in the Literature. in This Paper, the Reiner-Riwlin Transformation Equation, Valid for Coaxial Cylinders Rheometers, is Developed for the Modified Bingham Model, which is an Extension of the Bingham Model with a Second Order Term in the Shear Rate. the Established Transformation is Shown to Be Compatible with the Reiner-Riwlin Equation for the Bingham and Herschel-Bulkley Models. its Validation is Further Proven by Means …

At the microscale, cantilever vibrations depend not only on the microstructure’s properties and geometry but also on the properties of the surrounding medium. In fact, when a microcantilever vibrates in a fluid, the fluid offers resistance to the motion of the beam. The study of the influence of the hydrodynamic force on the microcantilever’s vibrational spectrum can be used to either (1) optimize the use of microcantilevers for chemical detection in liquid media or (2) extract the mechanical properties of the fluid. The classical method for application (1) in gas is to operate the microcantilever in the dynamic transverse bending …
