Pro-Civil Asphalt Plant

Due to the recent acquisition of our Asphalt plant it seems only fit to provide our future customers with an insight into how it works.

Step 1: Aggregate

At the beginning of the process we begin with aggregate which consists of a mixture of crushed stone, gravel and sand. Aggregate is generally stored in cold feed bins or stockpile.

Step 2: Cold Feed Bins

The stockpiled aggregate is sorted into separate, unheated bins. The aggregate is accurately measured through adjustable gates and variable speed belts ensuring the balance is correct upon entering the drying drum on a conveyor belt.

Step 3: Drying Drum

Upon entering the dryer drum, the aggregates are exposed to extreme heat from a burner whilst being tumbled at the same time. During this process in the drum asphalt cement is then added to the heated aggregate helping mesh the particles together. Furthering the efficiency of materials the emission control system recycles what would otherwise be wasted aggregate particles.

Step 4: Emission Control System

Due to the heating process of the aggregate, when the hot air is expelled from the drum any possible pollutants such as fine dust and sand are captured in the emission control system, upon which they will be circulated back into the drum minimising mess and waste.

Step 5: Batch Tower

The aggregate is then moved to the tower of which it is separated into varying portions for the right batch and stored in hot bins. After the correct portions are accumulated for a batch they are the, dropped into a pugmill where asphalt cement is added. Once the hot mix is complete it is then loaded directly onto a truck upon which it is delivered to a work site.
