Laboratory evaluation of Rediset modified bitumen based on rheology and adhesion properties [PDF]

open access: yes, 2017
Warm mix asphalt (WMA) could significantly reduce the production temperature of asphalt mixtures. Lower production temperature meaning reduced fossil fuel consumption and greenhouse gas emission which in turn avoid environmental pollution in the road ...

Analysis of dynamic mechanical response in torsion [PDF]

open access: yes, 2016
We investigate the dynamic response of industrial rubbers (styrene-butadiene random copolymers, SBR) in torsion and compare against common small amplitude oscillatory shear measurements by using a torsion rectangular fixture, a modified torsion ...

Imprinting the memory into paste and its visualization as crack patterns in drying process

open access: yes, 2005
In the drying process of paste, we can imprint into the paste the order how it should be broken in the future. That is, if we vibrate the paste before it is dried, it remembers the direction of the initial external vibration, and the morphology of ...
