INTRODUCTION
Within This Page
Pavements are the essential connector within DoD Installations, airfields, waterfronts, and to and from adjacent communities. Pavements include both concrete and asphalt surfaces that create the following:
- Airfield runways, parking ramps and hangars
- Roads
- Bridges
- Waterfront
- Piers
- Dry-docks
- Sidewalks
- Walking paths
- Walkways (elevated)
Corrosion impacts these surfaces in the following manner:
- Asphalt binder breakdown
- Loss of flexibility
- Cracking & pothole failure
- Base course & structural failure
- Concrete reinforcing steel corrosion (spalling)
Corrosion stressors include:
- Thermal & Photo Oxidation
- Ultra-violet Radiation degradation
- Freeze Thaw (Frost Heave)
- Corrosion of reinforcing steel (Concrete Pavements)
- Chemical impacts (salt & other chemicals)
- Heat impacts of jet blast
- Interaction of aircraft with the pavement (e.g. friction loss, surface breakdown, etc.)
Operational and Mission Impacts can be serious and include the following:
- For operational pavements such as airfields & critical road infrastructure, loss of mission capability affecting the National Defense.
- For roads & related pavements, inability to support designed functions creating delays, congestion, disruption.
- For bridges, access denial and life safety.
- For dry docks and waterfront pavements, loss of mission capability, life safety.
DESCRIPTION
Pavements represent the lifeline between essential requirements. Corrosion impacts are extensive and pervasive. The cost to construct these facilities is significant, but sustaining them is much more of a challenge. Keeping facilities infrastructure operational is a full time task requiring ever increasing resources. It is often easier to avoid or defer pavement repairs while they are seemingly functional. Failure can be both gradual and catastrophic. In both instances the cost to defer essential repairs is costly and mission impacting.
These pictures provide a small sample of concrete and asphalt failure issues. The cost to repair these pavement facilities is not trivial.

Pavement Challenges
Understanding the pavement technology, design, construction and sustainment and the associated risks and stresses is an absolute must for engineers, architects and sustainment engineers. Salt water is an excellent electrolyte contributing to an aggressive corrosive environment. Hydrostatic forces, wind, salt spray, ultraviolet radiation, temperature variations, frost, heave, surface erosion, asphalt binder failure all contribute to corrosion and erosion of concrete and asphalt pavements. Utilizing sustainment management system tools such as Paver™ will assist the installation in tracking pavement facilities and identifying maintenance requirements such that they can be funded and sustained.
Pavement Management Techniques
Methods of Corrosion Control for Pavements include:
- Utilizing an SMS tool such as Paver
- Good design practice
- Good construction practice
- Good Quality Control and Quality Assurance focused on CPC in pavements
- Corrosion awareness and facility monitoring
- Material selection
- Selection of appropriate surface treatments
- Proactive sustainment management
- CPC Training
Through understanding the severity and stresses associated with pavement design and construction and pavement sustainment, new and existing pavements will have a greater possibility of meeting mission requirements over the life cycle. It is essential that the right materials are selected, installed and maintained. Pavements have to hold up to repetitive stresses and forces that can be marginalized by corrosion stressors. The engineer, architect and sustainment professional should seek assistance of SMEs in this area to ensure that their projects will remain durable and sustainable over the desired life cycle. The extensive list of Resources listed below is an indication of the enormity of issues associated with concrete and asphalt pavements.
Consulting a Pavements Subject Matter Expert (SME)
Pavement Discipline Area SMEs provide invaluable consultation skills developed from years of experience assessing corrosion prevention requirements and many environments. The SMEs can translate local conditions into the interdisciplinary solutions that provide immediate and long-term benefits to the installation and its SRM bottom line costs. Typical consulting services provided by the SMEs include:
- Multi-discipline coordination and understanding
- Airfield pavement friction analysis
- Bridge inspections
- Materials analysis and selection
- Problem assessment
- Failure analysis
- Environmental Severity impacts
- System and material selection
- Review and assessment of contractor deliverables
- Quality assurance
- System design
- SRM analysis and recommendations (system inspection and testing assistance)
- Hazards analysis
- Assessment of the sustainability and durability of new technologies
- Process analysis
- Anti-terrorism threat analysis and protection technologies
