1/5/2017 · For hot mix asphalt plants, the energy consumption ranged from 84 kWh/t to 118 kWh/t; the average energy consumption was 99 kWh/t (356 MJ/t). For warm mix asphalt, the average energy consumption was 63 kWh/t (226 MJ/t) . Therefore, a warm mix asphalt plant can save 25%‒47% energy compared to hot mix asphalt plants.
A machine for providing hot-in-place recycling and repaving of an existing asphalt-based pavement, in which the pavement is first heated. Using this machine the heated pavement surface is then scarified, and new aggregate is dispensed onto it, to form a recycled

measured in different ways. In batch plants the asphalt cement may be measured by weigh tanks from which it is pumped to the spray bar or by asphalt meters. In continuous plants the asphalt cement may be measured by pre-set pumps interlocked
Apparatus is disclosed for continuous preparation of a blend of liquid sulfur in fluid asphalt in specified proportions to provide a dispersion of fine sulfur droplets in the asphalt, particularly suitable for coating onto aggregate to form "hot mix" for asphalt concrete of improved strength.

The plant's single-drum counterflow system uses the latest in innovative technology,
A common method is to combine RAP with virgin asphalt binder and aggregate in either a continuous plant (Drum) or batch (Pug Mill) central mixing plant to produce new pavement mixtures. In the United States these combined mixtures are generally restricted to a maximum content of about 50%, more commonly from 10% to about 25% of "RAP" due to a decrease in pavement performance as the RAP
10/4/2017 · For Stage Four (30–40% RAP) and Five (40–50% RAP) recycling, continuous mix plants with the double barrel dryer/mixer are most desirable. A counter-flow dryer with an outer aggregate blending chamber, like the double RAP dryer, is the best option for batch plants producing high …
