Special Services:  Forensic Investigations


PRI’s forensic-investigation services can support litigation efforts and/or help resolve conflicts for material producers/suppliers, product manufacturers, and system builders (contractors). These investigations often focus on material, product, and/or system underperformance. Typically the goal is to identify the underlying problem and provide clients with a suitable solution.

PRI’s forensic investigations are supported by:
  • Our extensive knowledge of asphalt, paving, roofing and associated material 
  • Our broad experience in asphalt technology: including processes, production, research and development, quality control/assurance, and performance
  • Our full complement of accreditations. PRI was the first fully accredited SUPERPAVETM laboratory in the nation, and it’s one of the only private laboratories in the United States to hold both AASHTO R 18 and ISO 17025 accreditations.
  • Our strong knowledge of all specifications and properties for a wide range of products
