INTEGRATING REGIONAL PAVEMENT TEMPERATURE INTO SIMPLIFIED MATERIAL CHARACTERIZATION FOR AIRPORT PAVEMENT RATING

Abstract

Indonesia currently complies with the Aircraft Classification Number – Pavement Classification Number (ACN-PCN) system for airport pavement rating. The outdated ACN-PCN system is known to be inconsistent with modern airport pavement design methods. To resolve this issue, the International Civil Aviation Organization (ICAO) introduced a new Aircraft Classification Rating – Pavement Classification Rating (ACR-PCR) system. The transition to ACR-PCR resulted in substantial expenses for the industry. The lack of an organized record of airport pavement construction posed a challenge in implementing the new system without a comprehensive yet costly pavement investigation. The objective of this study is to propose simplified and rational methods for the characterization of airport flexible pavement material that is compatible with the newly published ACR-PCR system. Implementation of the proposed method is demonstrated through an example case. This study compares the pavement rating between material characteristics proposed by the method and values obtained from the field non-destructive pavement deflection test. The proposed method integrates the Asphalt Concrete (AC) modulus prediction model based on pavement temperature observation. Analysis was performed using FAARFIELD and ICAO-ACR computer programs. The results show that the proposed method would exhibit a more conservative rating for the pavement. This method is expected to provide a practical and cost-effective solution for airports, particularly those with limited funding, in transitioning to the ICAO ACR-PCR system.
