ECONOMICAL CONSIDERATIONS ON DIFFERENT TYPES OF ASPHALT PLANTS

Limited availability of raw materials and energy sources make the proper selection and use of asphalt plants most important. Considerations in choosing an asphalt plant include: hourly production as a function of rational plant use; ecological problems in relation to possible energy savings; fuel savings made possible by reduced dryer temperatures; savings that can be achieved by using asphalt plants that ensure perfect metering of liquid asphalt and aggregates; and savings made possible by the use of properly sized aggregates to avoid rejected mix. Drum mixer plants have the advantages of lower purchase price, lower power and fuel consumption, lower spare parts requirements, and lower erection and transport costs, but involve the employment of more highly trained technicians than the conventional plant, and require high cost aggregates, as the plant cannot adjust the gradings.
