Activities

The research-development-application activities mainly cover the following aspects :

• the design of bituminous surfacings and bituminous mixes with a higher resistance to rutting, such as porous asphalt and stone mastic asphalt (SMA);
• the recycling of demolition materials from roads, the use of industrial wastes and by-products (rubber, cellulose, roofing in bituminous mixes);
• the renovation of cracked surfacings by using interlayer systems to delay and slow the propagation of cracks;
• the behaviour of pavement structural and surface characteristics under traffic;
• maintenance management systems for secundary roads (VIAGERENDA®);
• equipment for visual inspection of roads;
• pavement surveying methods : evenness, transverse profile, rutting, deflection, skid resistance;
• the surface texture of road pavements;
• traffic characteristics, traffic counts, classification, static and dynamic axle loads;
• drainage, sewer systems, hydrometeorological measurements, sewer surveys, sewer inspection with a video camera;
• air-entraining agents, the frost-susceptibility of concrete;
• noise pollution;
• speed-reducing devices;
• road markings, signing and safety on work sites;
• transport models for economic, environmental and safety assessments.

Standardization is also a major concern, together with regulation and certification.

BRRC develops products or services that can be proposed to the sector, e.g. a maintenance management system or software for asphalt mix design, and carries out specific studies and tests, check tests and expert studies.
