The Laboratory for Asphalts and Bitumen-Based Products

  • ASFALTS and BITUMENS – laboratory tests and field investigations
  • BITUMEN-BASED WATERPROOFING PRODUCTS – laboratory tests and field investigations
  • QUALITY CONTROL of the materials used and the execution of asphalting and waterproofing works – during installation and throughout the lifetime of the products
  • CONSULTING in the field of asphalts, bitumens, and bitumen-based products
  • DYNAMIC TESTS of asphalt mixes
  • SUSTAINABLE CONSTRUCTION – the use of recycled materials, LCA analyses
  • CERTIFICATION – authorized persons for the assessment of systems of factory production control for asphalts, bitumens, and bitumen-based waterproofing materials
