COMPARISON OF RIGID PAVEMENT DESIGNS FOR AIRPORT RUNWAYS UNDER STRONG AND WEAK GROUND CONDITIONS AT LOW AND HIGH TRAFFIC AIRPORTS

Abstract

In this study, the FAARFIELD program was used to evaluate the construction of rigid pavements for the airport under different soil conditions, aircraft types, and annual traffic loads (number of take-offs). This is because take-off movements are important parameters for runway strength in design. In addition, gross weight values for each aircraft type were entered into the system and obtained from the system with annual tariff growth rates. For pavement life, 20-year periods were considered. The study includes 2 different traffic loads: low and high traffic. The high traffic study is an example of 1 year of flight operations (1 year of total departures for each aircraft type) at a hub airport with +50 million passengers per year. Low traffic is Air Traffic Management (ATM) traffic for 1 year of total departures at a small local/regional airport. The CBR (California Bearing Ratio) value was taken as 5 for low strength soil and CBR=15 for good soil. CDF (Cumulative Damage Factor) and P/C values were examined in the results of the data obtained from the analysis of rigid pavement designs for airport runways under strong and weak soil conditions for low and high traffic airports with the FAARFIELD program.
