ASTECH modified asphalt plant

The production of polymer-modified asphalt (PmB) has a tradition at COLAS stretching back many decades. The Central European region also became part of this tradition in 1997 with the founding of ASTECH, s.r.o., which has its headquarters and production facility in Jihlava. The goal was to bring the company’s own production of modified asphalts to market under the trade name Colflex®. A new ASTECH plant in Holubice near Brno was opened in 2016. This new production facility utilises the latest technology in the field of polymer-modified asphalts, increases the quality of manufactured products and ensures the high reliability of supplies.

TECHNOLOGY

The production uses proven basic asphalt from regional refineries, polymers from renowned manufacturers, various additional additives and Colas SA’s own technology for the actual modification process. The advantage of the employed technology is very high flexibility in the production of Colflex asphalts and other products. The quality of input materials and products is inspected by an accredited laboratory at the plant specialising exclusively in the testing of basic and modified asphalts.

PRODUCTS

Colfex® is offered for a wide range of uses in various quality classes. These quality classes are in line with the EN 14023 standard and carry the CE label.

Product line pursuant to ČSN EN 14023:
Colflex® 10/40-65
Colflex® 25/55-55
Colflex® 25/55-60
Colflex® 25/55-65

Colflex® 45/80-55

The ASTECH plant also regularly supplies less common types of PmB, e.g. pursuant to STN EN 14023 (Colflex® 45/80-75 SK, Colflex® 40/100-65 SK, Colflex® 65/105-55 SK and Colflex® 65/105-65 SK).

Upon special request of the customer, ASTECH also manufactures PmB for cast asphalts, low-temperature PmB, highly modified SBS concentrates and other products.

Additional possibilities for non-standard production of asphalt materials are provided by a filling line for production and filling and packaging of special products (highly modified soft asphalts).
