PRI LOGO

Asphalts: Roofing (BUR's, Oxidized (Shingle Coatings), Modified Bitumens (MB's), Others)
PRI provides complete technical support for all types of asphalts used in roofing products and systems.

Our ‘A – Z’ capabilities range from preparing fluxes for air blowing (oxidation) from crude by distillation, to prototype compound development (air blowing or polymer modification), through comprehensive performance property evaluations (including accelerated and outdoor weathering) of finished /prototype products.

PRI’s third party independent testing, evaluation and product certifications for roofing asphalts and products support the commercial markets. PRI’s private sector confidential research and product development / improvements capabilities are routinely used by material suppliers and product manufacturers.

Below is a listing of our more common requests. Other testing protocols are available; inquire if the specific test or property is not listed.
