The Research & Development department, located at the heart of PR Industrie’s production and storage platform in France, is the warrant of the company’s technological innovation and has allowed it to move forward for the last 25 years ongoing. Thanks to state-of-the-art equipment (normative or research investigation), the research teams push PR Industrie’s product range forward by studying - among others - rheology of materials (master curves, evolution of fatigue, …). In association with the expertise of quality control and formulation laboratories, the R&D department resolves current road construction issues while conceiving the additives of tomorrow.
Rheology of bitumen
Study of the complex shear modulus on two straight bitumen and one bitumen with 6% PR FLEX 20®.
Characterisation of asphalt mixtures
Rut depth according to EN 12697-22
Formulation including rounded river aggregates + 6% 50/70 bitumen
Increase of stiffness modulus and stabilization of fatigue
QUALITY CONTROL LABORATORY
In order to guarantee an optimal quality of its additives, PR Industrie has a production-dedicated laboratory responsible for the control and validation of all raw materials and end products. This laboratory is responsible for the implementation of a continuous control procedure according to a multidisciplinary specifications sheet integrating polymer chemistry and asphalt testing. Each production batch is accompanied by an analysis certificate that validates various parameters to allow total traceability of our products.
ASPHALT MIX FORMULATION LABORATORY
- Fully equipped laboratory
- European and American norm (ASTM, AASHTO)
- Elaboration of equivalent formulations
PR Industrie has an asphalt formulation laboratory with a strong expertise on worldwide pavement testing standards. Formulation according to current standards (European norms, SUPERPAVE, PG…) is possible due to over 20 years of experience of its staffs and complete equipment. This tool allows a collaborative approach with various partners around the world to address their technical and economical issues integrating PR Industrie solutions.
