  • Study on Roughness Evaluation of Airport Pavements Based on Aircraft Response
    JOURNAL OF PAVEMENT ENGINEERING JSCE, 2004
    Co-Authors: Yukitomo Tsubokawa, Yoshitaka Hachiya, Qinxi Dong, Kenji Himeno, Akira Kawamura

    Abstract:

    The purpose of this study is to develop roughness criteria of airport pavements based on Aircraft Response to ensure the safety in operation and the ride comfortability of Aircraft. As the results, relationship between Aircraft vertical acceleration and roughness of pavement was clarified using simulation program of Aircraft Response, APRas, and the roughness criteria in order to keep Aircraft vertical acceleration under 0.4g for both runway and taxiway were obtained. To verify these roughness criteria, longitudinal profile was measured on runway of major domestic airport for three years, and roughness evaluation of the airport pavements was carried out using these criteria.

  • Airport pavement roughness evaluation based on Aircraft Response
    Health Monitoring and Smart Nondestructive Evaluation of Structural and Biological Systems III, 2004
    Co-Authors: Qinxi Dong, Akira Kawamura, Yoshitaka Hachiya, Kenji Himeno, Katsura Endo, Kunihito Matsui

    Abstract:

    Runway roughness affects primarily ride quality and dynamic wheel loads. The forces applied onto the airport pavement by Aircraft vary instantaneously above and blow the static weight, which in turn increase the runway roughness. One method to effectively assess the ride quality of the airport runway is to measure its longitudinal profile and numerical simulate Aircraft Response performing a takeoff, landing or taxiing on that profile data. In this study the Aircraft Responses excited as the Aircraft accelerates or moves at a constant speed on the runway during takeoff and taxi are computed by using the improved computer program TAXI. This procedure is capable of taking into account both the effects of discrete runway bumps and runway roughness. Thus, sections of significant dynamic Response can be determined, and the maintenance and rehabilitation works for airport runways will be conducted.

  • Aircraft Response based airport pavement roughness evaluation
    Doboku Gakkai Ronbunshu, 1999
    Co-Authors: Yoshitaka Hachiya, Jianjun Yin, Osamu Takahashi, Kenji Himeno

    Abstract:

    Airport pavement roughness is studied including both the subjective evaluation and digital simulation. Pilots’ subjective evaluation on surface characteristics is clarified by questionnaires, which indicates that the roughness is one of the most highly influential factors on riding quality and safety. The Response of Aircraft motion to the longitudinal profiles of airport pavements when departing on runways and taxiing on taxiways was simulated using the program TAXI. The results indicate that the Aircraft Response varies not only with the surface characteristics (i. e., the amplitudes and wavelengths of the profile), but also with Aircraft speed. Finally, roughness criteria for runways and taxiways are proposed.
