AN INVESTIGATION OF SURFACE PROFILE AND PAVEMENT STRUCTURE ON LIQUEFACTION EXPERIMENT SITE

Abstract

This paper reports an investigation on liquefaction experiment site. In the experiment, surface deformation and FWD deflection were measured on asphalt and concrete pavements which were on improved ground for liquefaction or unimproved one. The result showed that difference of elevation between pavement on improved ground and unimproved one were approximately 30 cm at most. The transformation of surface deformation continued for only a few hours. FWD deflection just after liquefaction exceeded that before liquefaction, and deflection kept decreasing for about seven day
