264-RAP : Asphalt Pavement Recycling

However, the current recycling procedures were almost exclusively gained from emulation of the Hot Mix Asphalt (HMA) process. There are several aspect of warm mix processes which are not properly understood, for example the blending potential between new bitumen and that from RA as well as effect of storage time on the extent of blending.

Aging Conditions for Hot Mix Asphalt Cracking Test

The aging level of asphalt mix in the laboratory needs to match that of asphalt materials in the field at the time of occurrence of pavement cracking. The 5-day aging at 95 Celsius (or 12 hours at 135 Celsius) simulates field aging of 7~10 years of asphalt surface layer. However, MDT often places chip seal within one year after the asphalt paving.
