ROAD PAVEMENT - Vulnerability Assessment
ROAD PAVEMENT - Vulnerability Assessment
-
Increased Flooding and Rainfall Intensity: Samoa's location in the Pacific exposes it to frequent tropical storms and cyclones, which are expected to increase in intensity due to climate change. The increased rainfall can lead to higher water volumes that ROAD PAVEMENT might not be designed to handle, potentially causing overtopping or structural failure.

- < 5,000 VPD
- < 10,000 VPD
- >10,000 VPD
-
Is the road prone to extensive pavement maintenance activities?
- No
- Maintenance occurs once per year
- Maintenance occurs twice per year
- Maintenance occurs more than three times per year
- High Maintenance Required
-
Is the road accessible during extreme weather events?
- Not Accessible extreme risk to public safety
- Accessible with some Risk to Public Safety
- Accessible during extreme weather events
-
How does heavy rainfall affect the road's general condition and usability?
- No affect - Good Drainage - Road Operates Well
- Some Affect - Moderate Drainage - Minor Maintenance
- Large Affect - Poor Drainage - Major Maintenance
-
Is there a history of flooding or coastal tidal or storm surge impacts affecting the road?
-
How often do road closures occur due to weather conditions?
- Road Closure <1 times per year
- More than 1 < Road Closure < less than 3 times per year
- Road Closure greater than >3 times per year
-
Is there an adequate drainage system in place to manage storm water runoff?
-
If the road was required to be closed for an extended period would it cause significant effect to the road network, communities, businesses and emergency services (i.e. Are alternative routes available)
- Alternative Route Available - Minimal Delays
- Alternative Route Available - Significant Delays
- No Alternative route Available - Extensive delays
-
