Dynamic characteristics of 100% cold recycled asphalt ...

2017-7-10  This paper aims at investigating the dynamic characteristics of 100% cold recycled asphalt mixture using asphalt emulsion (CRME) and cement. Firstly, dynamic modulus and phase angle of CRME are studied at different curing times. Then, creep and relaxation of CRME are also studied to determine its response at service condition with higher ...

Rheological behavior of cold recycled asphalt materials ...

2017-7-17  However, despite their commendable performance in the field, the cold recycled emulsified asphalt materials (CRM) has yet to be adequately characterized with respect to their rheological properties. This study was undertaken to evaluate the rheological behavior of the CRM with four different combinations of RAP (50, 75, 85, and 100%).
