Asphalt Mixing Plants generally fall into three categories:-
• Batch mixing
• Continuous mixing
• Drum-Mixing plants
Within each of those categories there occur various types of mixing plants ranging from small rotary paddle mixers used for the preparation of small quantities of patching premix, to large plants for producing tonnes of asphalt in a single batch.
The four main functions of any mixing plant are:-
• Heating and drying the aggregates.
• Proportioning the various sizes of aggregate, filler and binder to give a correctly proportioned batch, or continuous flow of material.
• Measuring the required quantities of aggregate, filler and binder to give a correctly proportioned batch, or continuous flow of material.
• Mixing the ingredients to produce a homogeneous material
