Evaluation of Long-Term Behavior of Cold Recycled

cially aged (weathered), recycled mixtures can be prepared and tested to simulate the long-term per­ formance of the recycled pavements. The objective of this study is to investigate the long-term effect of emulsified asphalt on the prop­ erties of cold-mixed recycled asphalt mixtures.

Comparing the Field and Laboratory Curing Behaviour of ...

The cold recycling of reclaimed asphalt (RA) for the rehabilitation of end-of-life pavements is becoming very common. Cold recycled asphalt mixtures (CRAMs) are characterised by a curing time, required to reach the material design mechanical performance. Since the laboratory simulation of the long-term field curing is not yet a standardised procedure, a CRAM was laid

Foamed asphalt cold-recycled mixtures have been increasingly used in China. However, the interlayer shear performance between the foamed asphalt cold-recycled layer and its top and bottom layers is still not clear. In this study, we explored factors affecting the interlayer shear performance of foamed asphalt cold-recycled layers (FACRL).

EVALUATION OF LONG-TERM BEHAVIOR OF COLD

The mixture was artificially aged by curing at 140 deg F up to 60 days and tested at different ages. The creep compliance of both virgin and recycled mixtures decreased rapidly at early ages due to the oxidation of the asphalt mixtures decreased rapidly at early ages due to the oxidation of the asphalt binder and then remained essentially the same.
