Evaluation of fatigue criteria for asphalt binders

TLDR
In this paper, a time sweep using the dynamic shear rheometer (DSR) has been proposed as an alternative test method for developing load-associated fatigue information for asphalt binders.
Abstract
The original SuperPave asphalt binder specification criterion for fatigue, G* sin δ, has received considerable criticism. Recently, a time sweep using the dynamic shear rheometer (DSR) has been proposed as an alternative test method for developing load-associated fatigue information for asphalt binders. This proposed test method is examined with respect to a phenomenon called edge fracture. Edge fracture is reported in the literature for steady state and oscillatory flow in DSR, but it has not been reported for asphalt binders. The modulus, when plotted versus number of cycles generated in a time sweep test, has the appearance typical of fatigue behavior; however, the actual response of the material depends markedly on the initial modulus of the material. The development of the modulus with repeated shearing is described with respect to flow of the asphalt binder at its circumference. The data are examined with respect to their validity as a measure of fatigue, and recommendations with respect to the use ...

Energy-Derived, Damage-Based Failure Criterion for Fatigue Testing:

TL;DR: In this paper, a method is presented for examining dissipated energy to select a consistent level of material behavior that is indicative of the damage accumulation in the mixture, showing the similarity between the constant stress and constant strain modes of testing and providing the potential for unifying the now phenomenological description of fatigue.

Anomalies in the normal force measurement when using a force rebalance transducer

TL;DR: In this paper, it was determined that the active nature of the transducer, which leads to excellent zero stability, causes thermal heating and consequent expansion of the system, and that the transducers length changes are the cause of the normal force anomalies.
