1/4/2021 · Asphalt emulsion can be used in a conventional hot mix plant but require lower mix temperatures. The advantage is greatly reduced emissions and less hardening of the asphalt binder. The higher viscosity of the base binder at the mix temperature allows thicker films to be deposited on open-graded aggregates.
20/11/2016 · Cold mix asphalt & hot mix asphalt • Cold mix is a mixture of unheated aggregate and emulsion or cutback and filler. The main difference between cold mix and hot mix asphalt is that aggregates and emulsion or cutbacks are mixed at ambient temperature (10°C-30°C) in case of cold mix and aggregates and binder are mixed at high temperature (138°C-160°C) in case of HMA.
The first step is to start running the plant, the cold feed, the dryer and the screens. After the plant has settled down so that the material in the bins is representative of the proportions established at the cold gates, a sample of aggregate is taken from each bin.

The characteristic of plant mixing recycling is to pull the old asphalt pavement back to the asphalt mixing plant. After being crushed and screened by the old material recovery system, it is added to the mixing equipment and mixed with the new aggregate to form a recycled mixture and transported to the construction site to pave the road. .
Cold aggregate supplying system of Asphalt Mixing Plant The cold aggregate supply system includes a cold aggregate belt feeder and a cold aggregate conveyor.The cold aggregate is measured by the belt feeder and graded according to the requirements of asphalt pavement construction .The cold aggregate conveyor collects and transfers the graded cold aggregate to the drying drum.
Mixing the cold mix asphalt emulsion with aggregate stone in the asphalt mixing plant would be enough, generally choose basalt, our asphalt aggregate mixing ratio is 5.5:100, which means one ton cold asphalt emulsion can produce out to 19.2 tons f
Cold Feeder with 4,5 or 6 bins – and extraction belts and a collection belt batches the aggregates depending on the demanded asphalt formula. Batching is made cubical through initial adjustment of the extract aggregate layer thickness from each bin, the required correction by the final batch depending on the variable speed of the extraction and collection belts.

The cold mix asphalt is a mixture of cold aggregate, filler and emulsion asphalt. The distinguished difference between cold mix asphalt and hot mix asphalt is the temperature. The cold mix asphalt blend aggregate, filler and emulsion asphalt at lower temperature of -20℃~50℃, while the hot mix asphalt mixture is mixed at high temperature of 138℃~160℃.
Asphalt Emulsion Cold Mix Manufacture. * cold mixes for pavement wearing courses. The two following manufacturing processes are available to make these three types of cold mixes: Cold mix, manufactured in a stationary plant, is normally intended for future use (from several hours to one month). The cold mixes are manufactured and used immediately.
