Road Asset Management System (RAMS) Lite
A simplified approach to Road Asset Management
Objective of RAMS
• Initial exposure
• Setup organisational policy
• Accessible / Cost effective RAMS
• Conform to asset management guidelines (TMH 22)
Components
• Road asset register
• Asset condition assessment
• Life cycle analysis
• Reporting
• Visualisation
• Gap analysis
Assets
Asset Register
• Roads links – uniform sections
• RISFSA classification
• Geo-location
• Asset components – Surfacing, base, abutments etc.
Field Assessment
• MOBICAP
– Geo-reference roads
– Assess pavement visual condition (TMH9)
Road Condition
• TMH 9 visual assessment
– Defects• Cracking
• Failures
• Functional condition
– Degree / extent rating
RAMS Analysis – MS Excel / VBA
• MS Excel environment
• Basis of analysis – asset visual condition
• Life cycle cost analysis
– Condition analysis
– Prioritisation
– Deterioration / Amelioration
– User and agency costs

LCA - Modelling of Road Condition
• M+R effects
– Adjust degree / extent
• Deterioration
– Sygmoidal model
– HDM 4 deterioration model

LCA – Maintenance and Rehabilitation
• M+R triggers– Defect / degree / extent
• Opex– Crack seal
– Patch
• Capex– Overlay
– In-situ recycle
– New construction

LCA - Prioritisation
• Road condition (TMH 9)
• RISFSA classification
– Strategic importance
– Socio-economic benefit
– Corridor development
• Traffic type and volume
LCA Output
• Road network condition
– Distribution based on available budgets
– Target / Current / Model

Conclusion
• Simplified approach to RAMS
• Foundation in basics of roads asset management
• First step to:
– Asset Register
– Level III / IV RAMS
– Integrated Asset Management
