RÖHRIG granit® – high-quality splittings at their very best!

RÖHRIG granit® manufactures double-broken granite chippings meant for road construction. In such fields of application as porous asphalts, surface layers with an outstanding brightness value, thin cold layers/coatings, and for conventional asphalt pavements – beginning from the base course layer up to the top layer – the double-broken chippings are used.

Double-broken granite chippings

Compared with common chippings, double-broken chippings meet the increased requirements with respect to frost resistance, under and over grain sizes (the so-called undersize and oversize materials) as well as towards grain shape in accordance with respective statutory regulations and guidelines.

Due to outstanding mineralogical properties, such as high PSV value and brightness, they can be used in special application areas.
