6. Design and Implementation of Road Maintenance Reform. Republic of Moldova
To carry out
• Describe the Road Network
– Data collection (condition data)
• Quantifying the amount of road works needed
• Timing the road works (periodic mtnce, rehab)
• Present a (usually) 3-5 year plan
• Check the available annual budget
• Adjust the planned activities
