The method has been the official ICAO pavement rating system for pavements intended for aircraft of apron (ramp) mass greater than 5700 kg from 1981 to 2020. [1] The method is scheduled to be replaced by the ACR-PCR method by November 28, 2024. [2] For the safe and efficient use of pavements, the method has been designed to:
