Automobile roads of general use. Technical requirements for the diagnosis and certification of highway engineering structures on automobile roads

2Scope / Description

1.1 This standard specifies the general requirements for the diagnosis and passporting of man-made structures on public transport roads. 1.2 The requirements of this standard apply to the following types of man-made structures:
　——Bridge structures (bridges, overpasses, viaducts, aqueducts, open bridges, livestock crossings, animal crossings, bridge-type biological crossings, etc.);
　——Man-made structures within the roadbed (fill-in overpasses, drainage culverts, or pipelines for any other purpose);
　——Tunnel structures (highway tunnels, pedestrian tunnels, tunnel-type biological crossings, etc.);
　——Avalanche protection structures (galleries, snow barriers);
　——Rockfall protection structures (galleries);
　——Drainage and diversion structures (drainage channels, drainage ramps);
　——Avalanche ramps, hillside pipes, sluice gates;
　——Retaining walls. 1.3 This standard does not apply to the diagnosis of man-made structures managed by river registries (ferry terminals, pontoon bridges), and hydraulic facilities that do not fall under the category of bridges crossing rivers (regulating facilities, bank protection facilities, etc.). 1.4 At the national level, additional and/or specific rules may be specified for this standard, which apply to the requirements for the diagnosis and passporting of artificial structures on bus routes, modifications thereof, and rules for the application or discontinuation of these documents in various countries.
