Filler is that portion of the aggregates passing the 0.075 mm sieve. It includes the combined mass of crusher dust, any added recycled fines from asphalt plant dust extraction filters and any added filler required to enhance the mix properties. Fine Aggregates. Fine aggregates are aggregates passing a 4.75 mm AS sieve. Hot Mix Asphalt (Asphalt)

Batch Plant Production. First, aggregate travels through the cold feed bins, where initial proportioning of the aggregate takes place. The quantity of material leaving each bin is regulated by the size of the gate opening, or the speed of a belt, or a combination of the two. The aggregate is sent to a drier.

Segregation - ON Asphalt

ASPHALT PLANTS Asphalt is produced in a batch or drum mix plant. The most sensitive areas for segregation on any plant include cold feed bins, surge bins and storage bins. On a batch plant it can also occur within the hot bins which are not present on the drum mix plant. Segregation in cold feed bins can be prevented by
