Why Coloured Asphalt, or Does Asphalt Always Have to be Black?

Individual colour design of asphalt from an architectural and aesthetic perspective, because of its effect as a signal in road construction, or as an alternative to coloured concrete surfaces is playing an increasing and hence more important role in the Central and Eastern European region. The forerunners here were initially France, England and the Benelux countries where there is higher potential because of the partly coloured design of motorways and cycling paths that are made of asphalt.

The colour scheme of the dyed asphalt was rather limited at the beginning because of universal use of (black) bitumen. Hence, for example, a brownish, more averagely attractive colour was achieved at most by adding a relatively large amount of red pigment (Figure A).

The range of colours was increased tremendously with the development of a "transparent" binding agent, e.g. DEKOBIT. The pigment industry offers an almost endless multitude of colour pigments, which are also outstanding for asphalt because of their resistance to light, weather and also temperature. In combination with a great variety of mineral rocks, almost all customer wishes can be fulfilled.

More and more urban planners and architects appreciate coloured asphalt for a great variety of projects. Whether it is to match the environment or to be offbeat and modern, a great deal can be realised.
