Concrete & Asphalt

Industrial Boilers America excels in the deployment of equipment for the manufacturing of coated roadstone which demand the combination of several aggregates, such as sand and a filler (such as stone dust), in the correct proportions, heated, and finally coated with a binder, usually bitumen based or, in some cases, tar (although tar was removed from BS4987 in 2001 and is not referred to in BSEN 13108/1). IBA equipment ensures the temperature of the finished product is kept in the range of 100 – 200 degrees Celsius and is workable after transport to its destination.

There are three main classes of plant: batch heater, semi-continuous (or “asphalt plant”), and continuous (or “drum mix”). The batch heater has the lowest throughput, the continuous plant the highest at up to around 500 Tonnes per hour.
