Welcome to BRRC


The Dynaplaque allows rapid checks of the bearing capacity of soils or subgrades with a maximum particle density Dmax smaller than 200 mm.


Iatroscan MK-6s TLC-FID Analyser

• Iatroscan (picture: MK-6s TLC-FID Analyser) is a chromatographic analysis technique for the characterization of bituminous binders. This technique is based on the separation and quantification of the main components of bitumens (saturated compounds, aromatic fractions, resins, asphaltenes). This affords better understanding of the chemical composition of bitumens (origin, compatibility with polymer additives, etc.) and of modifications induced by external factors such as exposure to air (e.g., during the ageing of binders). The technique can also be used for the quantification of additives in (mastic) asphalt produced at a reduced temperature.

Iatroscan is complementary to other techniques for rheological or mechanical characterization available at BRRC.

Differential Scanning Calorimetry

Differential Scanning Calorimetry (DSC) is a calorimetric analysis technique for very accurate measurements of heat flows from and to materials within a wide range of temperatures (e.g., -80 °C to +500 °C). This makes it possible to determine the phase behaviour and the (in)stability of materials as a function of temperature (melting point or range, crystallization point, vitreous transition, specific heat, melting and crystallization heat, etc.).

DSC is complementary to other techniques for rheological or mechanical characterization available at BRRC.

Tomorrow’s Road Infrastructure Monitoring & Management (TRIMM)


Core Tasks (1)


The TRIMM project (acronym of Tomorrow’s Road Infrastructure Monitoring & Management) was completed late in 2014. It was funded under the European Union’s Seventh Framework Programme for research (FP7, 2007-2013). Its objective was to strengthen the role of condition monitoring in road management and to highlight its beneficial effects. The condition of a road network is, in fact, decisive for its level of service to road users. Maintenance is required to preserve or improve the condition of bridges and roads.


Device for two-point bending test

Various types of asphalt mixture are used on our road network. Their compositions have to comply with performance criteria set in the tender specifications of the various road-managing authorities. Performance tests are used to check this compliance. One of these tests is the two-point bending test (picture: new device at BRRC) on trapezoidal specimens, to determine the rigidity modulus and investigate resistance to fatigue.

Workshop on the Curviameter: Interpretation and Exploitation of Measurements

On January 28 and 29 2015, the Belgian Road Research Centre hosted a workshop on the Curviameter. The objective of the workshop was to bring together specialists and users of Curviameter measurement data: current and former end-users of Curviameter data, road managers and road engineers, scientists who published articles about the interpretation of Curviameter data, and persons interested in the measurement device and in the data it provides.


6th European FWD User Group Meeting – Structural Condition Assessment

Areas of Expertise (1)


Core Tasks (1)


On 10 and 11 June 2010, the Belgian Road Research Centre hosted a seminar devoted to the FWD (Falling Weight Deflectometer) and Structural Condition Assessment.


Road management

Road network management is not limited to the more technical aspects of the contruction, maintenance and repair of a given number of roads. Other considerations involved in the management of a road network include the available annual budget, the share-out between road maintenance and (re)construction, the safety and comfort of road users, mobility, noise annoyance, environmental preservation, aesthetic aspects, sociological impact, etc.


Tools for road managers (for an objective and rational comprehensive approach to road management) – BRRC Synthesis F48/14

Several actors are in charge of constructing and maintaining road infrastructure. They may be regions or municipalities, but also managers of specific facilities such airfield strips, port areas, industrial areas, etc. All of them, however, are faced with the same challenges raised by ageing infrastructures, ever increasing traffic loads, and budget restrictions.

The quality of road infrastructure is important to all actors, but is perceived in different ways:

Quality control of earthworks and (sub)base layers

Both at the European and the global level, exchange and work structures are developing that foster technical progress in earthworks and earthmoving projects. They promote:
- a coordination of practices (establishment of standards institute);
- greater participation in research at the European and global levels;
- the scheduling of conferences for exchanges between professionals.
