Research Abstract	The limit value of rut depth of runway and taxiway in Japan was decided empirically. However the groove is constructed on runway surface to enhanced drain performance of the runway, there is no limit value of groove deformation in maintenance stage of runway pavement. If rut depth become large or groove is worn down due to the running of aircraft on runway and taxiway, hydroplaning may occur. This study is conducted analytically to clarify the effect of rut depth and shape of groove on drain performance of runway and taxiway.
