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.
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:
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.
BRRC has recently launched its new website. The well-known address, www.brrc.be, has conveniently been preserved.
The updated and completed texts have been fully translated into English, as a complement to the traditionally available French and Dutch versions.
The concept of the site is daring, since its content is not presented primarily in the form of a conventional tree structure.
This test is used to determine the permeability of a water-permeable structure in situ. The apparatus consists mainly of two rings (Ø. 50 and 70 cm), a continuous water supply unit and an automatic system to maintain a constant water level.
Road geotechnics has considerably extended its scope of activity over the past few years. This is due to the cosideration given to environmental preservation and sustainable development, and to the ensuing legal obligation to be careful in general with the available natural resources left and to optimize soil use in road earthworks.
Making valuable use of local – including marginal – materials excavated during earthworks is currently a major concern (see PIARC report 1201R37 on “Innovative approaches towards the use of locally available natural marginal materials”).
