Abstract
Light weight deflectometer (LWD) has been widely used for quality assurance in road construction, in particular compaction of both chemically treated subgrade soil and aggregate subbase. However, it has been recognized that LWD measurements vary with many factors. Based on LWD tests in actual road construction, this presentation provides updated information on the LWD deflection measurements for both chemically treated subgrade soil and aggregate subbase.
