  Safety Inspections of Road Tunnels

  Road tunnels have several systems to ensure a good exploitation of the tunnels, both in regular and emergency conditions. These systems must be inspected periodically to verify whether they work properly. In Brazil, these kind of inspections are mandatory every 3 years, as stated in Brazilian legislation, ABNT NBR 15661 “Proteção contra incêndio em túneis”.In Spain, these inspections are compulsory according to Royal Decree (RD) 635/2006 about minimum safety requirements in Spanish road tunnels. Within this context, in June of 2010 the Road Department of Ministry of Public Works (DGC) gave the start for the contract “Tunnels’ Inspection, according to RD 635/2006, Zone 1 (North) of Spanish road tunnels”. In this paper a summary of the inspection works is presented, developed between 2010 and 2012, in tunnels of the Spanish Road Network (SRN) located in the North of Spain.
