An error occurred while processing the template. 
The following has evaluated to null or missing:
==> link_to_page.getData()?eval.name  [in template "20155#20195#RIBBON" at line 15, column 45]

----
Tip: It's the step after the last dot that caused this error, not those before it.
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??

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)

Flexible Plug Expansion Joints For Road Bridges
(according to draft EAD120011-01-0107 and 120093-00-0107 /ETAG 032-3)

  • Movement capacity test under slow occurring movements at various temperatures with DJMS (Dynamic Joint Movement Simulator)

  • Water tightness test

  • Overrolling test (resistance to fatigue) with MMLS3
