A Study on the Factors Affecting on the Remaining Life of Airfield Concrete Pavement

Airfield concrete pavement evaluation methodology has classified into two categories, One is using the reverse of pavement design process, in which flexural strength of the concrete and past franc is used, and the other is using a mechanistic logic in which elastic modulus are basically used. But it has been skeptical if the flexural strength or modulus of concrete is really an indicative of remaining life. In this study various field tests, as well as lab test, were conducted in loading zone and unloading zone in an old airfield pavement. As a result, It was found from the study that the most important factor affecting on the remaining life was load transfer efficiency rather than flexural or elastic modulus. A validation test was conducted on an other airfield pavement.
