Maintenance of the highway network must consider the following priority order:
1º Paved Highway Network 2º Unpaved Basic Network 3º Primary Local Network 4º Secondary Local Network
Generate the best possible capacity for management and control of the highway network in the regional and provincial spheres.
Use the Technical Specifications in the Highway Manual,
Volume 7, “Highway Maintenance” in all bidding for maintenance
works.
3. Maintenance Policies
Mini

as In all maintenance activities, consider aspects of highway safety, informative signage, the environment, and citizen participation as appropriate.
Planning for maintenance of the highway network should utililze:
The SAM methodology for routine maintenance.
Models of the HDM type for periodic maintenance.
Models of prioritization of works. Inventory of Highway Maintenance.
Basic roads: for the gravel and dirt network, solutions of “Basic Roads” should be attempted where possible.
