Quantitative evaluation of rejuvenators to restore embrittlement temperatures in oxidized asphalt mixtures using acoustic emission source location techniques
… concrete, and its ability of restoring asphalt's embrittlement temperature was quantitatively investigated in this study using acoustic emission analysis and source location techniques. Four asphalt specimens, which have been oven-aged for 36 hours, were tested using the same acoustic emission …

Effects of asphalt rejuvenator on thermal and mechanical properties of oxidized hot mixed asphalt
… emission (AE) testing for determining the embrittlement temperature of the mixtures. During the DC(T) testing the fracture energies and peak loads were used to measure the resistance of the rejuvenated asphalt to low temperature cracking. The AE testing monitored the emissions generated …

Quantitative evaluation of low-temperature performance of sustainable asphalt mixtures and binders containing recycled asphalt shingles (RAS) and rejuvenators
… emission (AE) based technique for estimating the embrittlement temperature of RAS-modified mixtures and asphalt binders prepared in the laboratory. During AE testing, the AE activities of mixture or binder specimens were monitored during cooling from room temperature to -50°C to estimate the onset …

The Safe Removal of Frozen Air from the Annulus of a Liquid Hydrogen Storage Tank
… is monitored in this region, the extremely cold temperature causes all but the helium and neon constituents of air to freeze. A small, often unnoticeable pressure rise is the result. As the leak persists, the quantity of frozen air increases, as does the thermal conductivity of the insulation …
