AIRFIELD PAVEMENT DESIGNPROPOSED ACPS DESIGN METHODOLOGY

OBJECTIVE OF ACPS DESIGN FOR AIRFIELD PAVEMENTS To meet the design criteria

Cumulative Damage Factor (CDF) Edge Stress of concrete slabs

To meet the requirement from ICAO by providing Aircraft Classification Number (ACN) Pavement Classification Number (PCN)

To meet standard international requirements for General Aviation (GA) and Non- General Aviation (Military aircrafts)

DESIGN RATIONAL FOR AIRPORT USING ACPS

The main design rational are To meet the requirement for the

Cumulative Damage Factor (CDF) below 1.0

To match the Edge Stress between the FAARFIELD requirement and the edge stress from the ACPS calculations

By meeting those two items above, the ACPS design is classified as “rational design” that meets the requirement of FAA and ICAO

ADVANTAGES OF ACPS Installed rapidly Cause minimum disruption Better construction of slab off-site (pre-cast) Better quality control of concrete materials (pre-cast) Better concrete curing regiment (controlled curing) More durable materials (K-400 concrete) Multi tasks (non-linear construction activities) during

panel installation in the project Field acceptance testing is minimal Longer life pavement, minimum maintenance

CONCLUSIONS Design of ACPS is based on the latest airport

pavement design software from FAA, FAARFIELD

Proposed ACPS Design is based on FAA Circular Cumulative Damage Factor Edge Stress Criteria

Meet the requirements of ICAO Aircraft Classification Number (ACN) Pavement Classification Number (PCN)
