Aggregates & Mixtures


If asphalt or concrete, the building material quality is mainly dependent on the employed aggregate condition. Due to our long-time experiences with on-site tests and laboratory tests our customers value us as a testing facility and monitoring agency but also as a competent consultant.

Our RAP-Stra certified laboratory offers you in addition to our independent test centre the following services:

  • verification suitability as foundation for a controlled quality monitoring,
  • external monitoring of layers without binding materials with natural and industrial fabricated aggregates and RC-building materials,
  • on-site tests of layers without binding materials,
  • internal production control and building material receiving inspection,
  • consultation on preparation, production and application of aggregates.
