Asphalt and bituminous applications

Bitumen as a useful binder in construction

Asphalt is one of the bituminous applications in construction and has played a decisive role in road construction in particular for years.

The advantage of asphalt in road construction over concrete roads lies in its higher mechanical load-bearing capacity in the face of dynamic stresses due to its flexible binder bitumen, a by-product of the petroleum industry. Bitumen also has a more favorable carbon footprint than the cement used in concrete roads. Furthermore, asphalt requires less maintenance than concrete.

In addition to the classic hot asphalt, cold asphalts processed at around 20 °C or even at lower temperatures are now also used in road construction, which increasingly optimizes the energy requirements of asphalt during processing.

However, other bituminous applications, such as bitumen membranes for roofs or bitumen coatings for exterior basement walls or plinth areas, which mainly have a sealing function against moisture or wetness, are products with high added value that are in demand in the construction sector.

Asphalt colouring

Since the binder bitumen in asphalt is black in most cases - there are also transparent bitumen grades that differ greatly in price from standard bitumen - the classic appearance of asphalt roads is relatively dark. As safety-relevant aspects in road traffic are becoming increasingly important, city and road planners of municipalities are repeatedly considering the possibility of coloring asphalts in their planning concepts.

Due to the differentiability of roads, sidewalks and bike paths, color pigments are always very popular. A dull appearance can thus be avoided in urban development by specifically adapting the outer appearance of the pavement to the surroundings in an elegant way and ensuring a harmonious appearance.

For the colouring of bituminous products such as asphalt to be as successful as possible, the product should be well broken down. This is made possible by our pigments specially adapted to this application.

Low-dust compact pigments ensure durability

In addition to our powder pigments, we offer you alternative low-dust compact pigments, which have established themselves globally over the last decades as a reliable and durable product in the market.

We also offer our pigments for asphalt in sustainable polyethylene bags, which can simply be added to the hot asphalt to be processed. This does not affect the mechanical properties of the asphalt and reduces your potential packaging waste to a minimum.
