Bituminous Materials

The Concrete and Asphalt Laboratory possesses modern testing equipment operated by an experienced team of technicians. Our team can help test your materials and answer your R&D questions.

In particular, we offer the following tests:

 

Binder

  • Conventional binder tests

  • Bitumen rheology using Dynamic Shear Rheometer (DSR)

  • Low temperature properties using Bending Beam Rheometer (BBR) and Fracture Toughness Test

  • Simulation of aging using Rolling Thin Film Oven Test (RTFOT) and Pressure Ageing Vessel (PAV)

  • Advanced characterization using Atomic Force Microscope with Nanoscale Infrared Spectroscopy (AFM-FTIR), Gel Permeation-Chromatography (GPC) and Infrared Spectroscopy (FTIR)

Asphalt mixture / Pavement

  • Conventional mixture tests

  • Dynamic tests (fatigue, stiffness, rutting, gyratory compaction)

  • Monotonic loading tests (interlayer shear test, indirect tensile test, semi-circular bend test)

  • Traffic load simulation in an environmental chamber using Model Mobile Load Simulator (MMLS3)
