Milemaker™ Asphalt Plant Offers Warm-Mix Capability

Asphalt Drum Mixers, Inc. (ADM) has added a warm-mix asphalt system to its Milemaker™ Series asphalt plants. The new system delivers even more versatility to the plants, which boast to be the most fuel-efficient, mix-design flexible and productive plants within the 145 to 385 t/h range.

Previously producing only hot-mix asphalt designs, the Milemaker now has the capability to introduce water or other chemicals into liquid asphalt entering the plant, thereby appropriately lowering the temperature to warm-mix specifications.

The dual-drum plants use counterflow technology, which operates separate drying and mixing zones to achieve the maximum level of heat transfer and fuel efficiency. This enables the Milemaker to achieve a high production volume and an extremely low cost-per-tonne average.

Milemaker plants, which are available in portable, relocatable or stationary versions, meet all federal and state specifications and consistently produce quality asphalt to help protect operators against out-of-spec damages. While producing the latest mix designs, the plants also come prepared for future job specifications since dual-drum systems easily can be adapted to accommodate new mix specifications.

A wide range of components further customizes each plant for particular customer needs. Available individual components include cold feed bins, hot oil asphalt cement tanks (both horizontal and vertical), direct-fired horizontal cement tanks, portable and stationary bag houses, mineral filler systems, recycled asphalt pavement systems, self-erect and stationary silos, weigh and drag conveyors, weigh batchers and fuel oil tanks.

ADM keeps the environment a priority in its designs. The Milemaker ranks as the most environmentally sound asphalt plant in its class. By using counter flow technology, it virtually eliminates unsafe hydrocarbon emissions, which are a common problem with other drum mix plants. The Milemaker produces the cleanest stack tests and also can handle large percentages of recycled asphalt pavement (RAP) without reducing the temperature or producing blue smoke. To make the Milemaker Series even more environmentally friendly, ADM designed the system to reintroduce residual gases back to the drum’s combustion zone.

The Milemaker’s design features a sophisticated, yet technically easy-to-operate control system. One plant operator and one loader operator can control the entire operation. A new operator can be trained within a few hours, and on-site staff will be able to handle nearly all maintenance procedures.

In addition to the Milemaker, ADM also offers the Roadbuilder Series and SPL Series. Each ADM plant can be custom designed to meet the requirements of individual sites.
