8 - ACR/PCR Explained: The New Standard for Airport Pavement Management

Описание: Dive into the future of airport infrastructure with this detailed explanation of the Aircraft/Pavement Classification Rating (ACR/PCR) system. This video breaks down the new era in airport pavement asset management, step by step.
What you will learn:
• The Core Principle: Understand the fundamental rule of ACR ≤ PCR for unrestricted aircraft operations.
• Key Changes: Discover how the new system uses advanced mechanistic-empirical procedures to calculate pavement strength and aircraft impact.
• Calculating ACR: Learn how the Aircraft Classification Rating (ACR) is determined for both flexible (asphalt) and rigid (concrete) pavements using the Derived Single Wheel Load (DSWL).
• Understanding PCR: We explain the Pavement Classification Rating (PCR) and its standardised reporting format (e.g., 800 F/C/W/T) published in the AIP.
• Cumulative Damage Factor (CDF): See visual examples of how different aircraft in a traffic mix (like the B777-300ER, A380, and A320neo) contribute to pavement wear.
• Overload Operations: Find out how airports can safely manage aircraft with an ACR higher than the pavement's PCR, assessing the actual impact on pavement life.
This new system overcomes the limitations of the old ACN-PCN method, allowing for optimised use of pavements for airport owners and optimised operating weights for airlines.
