Shake table tests on deformation profile and FWD deflection of pavement after liquefaction of foundation

Abstract

Shake table tests of large model in 1g gravitational field were conducted to estimate deformation characteristic of asphalt pavement and change of bearing capacity of foundation caused by liquefaction during and after earthquake. FWD used for the maintenance management and damage survey after earthquake of actual airport pavement to confirm of bearing capacity was used for these shake table tests. As a result, subsidence of asphalt pavement became large with rise grade of excess pore water pressure. And FWD deflection of about 1 hour after became smaller than that before shaking, and the result which the bearing capacity of the foundation increases was obtained.
