Antoun’s Project on MAPMP Expedient Pavement
Melbourne Airport Accelerated Pavement Rehabilitation – Slab Replacement Program
Antoun was commissioned to execute a critical airport concrete rehabilitation initiative at Melbourne Airport, encompassing works on Taxiway Kilo and Runway 16. The project involved the expedited replacement of 32 deteriorated rigid pavement slabs in one of the busiest 24-hour airports globally, ensuring continuous aerodrome operations throughout.
Significantly, this project formed the empirical case study for an academic article published in the International Journal of Pavement Engineering, titled “On-site strain and temperature monitoring of belitic calcium sulfoaluminate cement concrete airport slabs: feasibility of maturity method” antoun.com.au+1. The study reflects the real-world application of maturity-based monitoring techniques, underscoring the project’s contribution to innovations in concrete performance tracking and quality assurance in airport pavement engineering.
Project Background and Rationale
The targeted sections of airport pavement had endured cumulative damage from sustained heavy aircraft loading, environmental exposure, and thermal cycles, leading to premature deterioration. Conventional reconstruction methods—characterised by extended setting and curing durations—were ruled out due to the risk they posed to flight scheduling and airport logistics.
In response, Antoun developed and implemented an accelerated concrete solution using airport high early strength concrete, enabling structural readiness within hours. This innovative approach, supported by maturity monitoring as detailed in the mentioned academic publication, allowed for after-hours concrete installation and ensured seamless reinstatement of operations each day.
Scope of Works
All works were confined to tightly managed six-hour night-time possession windows and encompassed:
- Demolition and removal of existing rigid airport slabs
- Placement of new Rapid Set Concrete slabs engineered for immediate structural performance
- Decommissioning, replacement, and reactivation of Airfield Ground Lighting (AGL) within the same shift
- Implementation of robust safety, environmental, and quality control protocols
- Management of PFAS contaminated airport concrete, retained on-site as per Melbourne Airport and Airport Environment Office guidelines for future reuse
Risk Management and Operational Coordination
Execution in an active airside environment demanded rigorous planning and multidisciplinary coordination. Key strategies included:
- Ensuring zero disruptions to aircraft movements and avoiding extended closures of taxiways or aprons
- Real-time collaboration with Melbourne Airport infrastructure teams, operations personnel, safety officers, and environmental compliance units
- Incorporation of maturity method monitoring, providing real-world performance data for each slab, enhancing the reliability of airport slab replacements
Over eight weeks, the Melbourne Airport accelerated pavement rehabilitation program successfully delivered:
- The replacement of 32 airport slabs with no impact on flight operations
- Daily reinstatement of all affected airport pavements to full operational capacity
- Integration of maturity monitoring technology, as explored in the academic paper, into broader airport pavement engineering practices
This project stands as a testament to Antoun’s leadership in airport infrastructure maintenance, merging innovative airport high early strength concrete methods with operational excellence—while contributing valuable research insights to the field.
