How do I determine the mix and compaction temperature?
By the way, to get the softening temperature plus 100 is single mixing temperature, however, it isn't a temperature range. How do I to apply it to HMA mix design when performing mixing procedure, especially for taking the modified asphalt binder?
Asphalt Rubber Methods of adding rubber to asphalt – Wet Process – rubber is added to the liquid asphalt binder before being mixed at the hot mix asphalt plant (i.e., rubber is wet before mixing) – Dry Process – rubber is added at the same time the asphal
