Modified bitumen rose to popularity in the 1960s since many worn-out upper layers of road pavement required reconditioning in many parts of the developed world. The traditional asphalt concrete failed to provide a reliable and durable road surface because of increased traffic and heavy load carrying vehicles.
The quality of bitumen is determined mainly by the characteristics of bitumen binders therefore, usual bitumen was changed by polymer modified bitumen. At first, different polymers were tested to be further combined with bitumen using laboratory units. Finally, the results were systemized though years of scientific research.
GlobeCore has designed the UMB-L laboratory unit to make modified bitumen formulations and to carry out different experiments at industrial facilities involved in asphalt concrete production used in the construction and repairing of roads and bridges.
The operational principle of this unit consists in the simultaneous dispersion of bitumen and polymer made possible by an advanced and precise colloid mill.
The following is a list of advantages of the GlobeCore UMB-L unit:
- experiments may be conducted directly at production sites;
- only a small amount of raw material is required to produce samples of modified bitumen;
- liquid components may be added during the production process;
- carrying out experimental technological processes to determine the amount of modifying additives, necessary to produce modified bitumen;
- equipment may be supplied separately or as a component of bitumen-emulsion production units;
- consultation and training of operational staff; and
- trouble-free operation.
