Abstract: The use of recycled materials can have significant economic value. With the increasing quantity of recycled material used in viscoelastic materials, especially asphalt mixture, understanding how they interact with original materials to produce a mixture that performs successfully, becomes critical. Currently, the technology to determine the effect of additives on the performance of asphalt mixture is lacking. The present invention relates to a new unified methodology for mechanical testing of asphalt mixture and other viscoelastic materials that improves the current practice in speed, convenience, and accuracy. A new improved specimen mounting method on Dynamic Shear Rheometer (DSR), a new recovery method for fine portion of asphalt mixture, and three new tests for the performance of recovered material using DSR is disclosed. The new methods provide performance grading of asphalt mixtures that is new to the industry and provide necessary tools for determining the effect of recycled materials on performance.

Abstract: Method for validating a resonator. The method comprises: providing a first set of resonator responses of the resonator pertaining to a first validation fluid, contacting the resonator and a second validation fluid, wherein the first and the second validation fluids have different viscoelastic properties, obtaining in contact with the second validation fluid a second set of resonator responses of the resonator, wherein each resonator response pertains to a resonance frequency or a dissipation of the resonator, validating the resonator by comparing a first and a second value, the first value being obtained from at least one resonator response of the first set of resonator responses and at least one resonator response from the second set of resonator responses, the second value being based on a relationship between frequency or dissipation responses of the resonator and a function of the viscoelastic properties of the first and the second validation fluid.

Abstract: Apparatuses and methods are disclosed for the analysing of non-Newtonian fluids and determining parameters to characterise the relationship between shear stresses and shear rates, i.e. the parameters of one or more rheological models of viscosity. A plurality of viscosity measurements are made in a fluid using one or more vibratory transducers operating at a plurality of frequencies. Parameters for the fluid are determined based on the measured viscosity values and the frequencies of vibration at which the viscosity measurements were obtained.

Abstract: An apparatus to determine fluid viscosities downhole in real-time includes a housing and an excitation element positioned therein. Electrical circuitry provides a drive signal that excites an excitation element into rotational oscillations. A detector produces a response signal correlating to the detected oscillating movement of the excitation element. Circuitry onboard the apparatus utilizes the drive and response signals to determine the fluid viscosity.

Abstract: Apparatus for the measurement of a fluid property is shown generally at (10). The apparatus is typically suitable for the measurement of a property of a fluid (not shown) such as its viscosity, and comprises a tube (12) for the through-flow of fluid to be measured, a torsion bar (14), a magnetic drive coil (16) and a magnetic pick-up coil (18). The tube (12) is mounted within a casing (20), shown in cutaway. An inertial frame (22) is secured to the casing via isolators (not shown). The tube (12) has a web portion (24) supporting inertial masses (26) connected to, and radially spaced from, the tube (12). The tube is connected at each end to pipe fittings (28) via end flanges (30) and seals (32). The single tube (12) has been selectively machined to produce areas (12a) of low compliance which effectively form springs. The torsion bar (14) is of relatively low inertia and is fixed at the midpoint of the length of the tube (12). The mass system (24, 26) is of much higher inertia and is fixed to the tube (12) as shown. The tube (12) is then fixed in frame (22) which is of even higher inertia, and held in place in casing (20) by means of fixing supports (not shown).

Abstract: A fluid properties measurement device, including a magnetically excited and sensed resonator and a resonator electromagnetic excitation assembly, including an excitation coil driven by an electrical network, electrically connected to the excitation coil. The excitation coil is positioned so that a varying magnetic field produced by the excitation coil will drive the resonator in a pattern of resonating movement that has predetermined characteristics. Also, an electromagnetic sensing assembly, including a gradiometric sense coil is positioned so that an electromagnetic field originating due to movement of the resonator in a pattern having the predetermined characteristics, will create a time-varying gradient across the sense coil. Finally, a signal sensing electrical network is electrically connected to the sense coil.

Abstract: The disclosure provides a label-free viscosity-based analyte detection system using paramagnetic beads as an asynchronous magnetic bead rotation (AMBR) microviscometer. It is disclosed herein that the bead rotation period is linearly proportional to the viscosity of a solution comprising analytes surrounding the paramagnetic bead. Optical measurement of asynchronous microbead motion determines solution viscosity precisely in microscale volumes, thus allowing an estimate of analyte concentration. The results demonstrate the feasibility of viscosity-based analyte detection using AMBR in microscale aqueous volumes.
