Review of Push-Off Tests for Base Friction of Cement Concrete Pavement
Keyword(s):
Concrete pavement slabs experience volume change due to the variation of temperature and moisture level. The frictional drag acting on the bottom of slab due to the base friction is in the opposite direction of horizontal slab displacement, and resist against the horizontal slab movements. The magnitude of frictional force and horizontal slab displacement has interdependent relationship. In the present study, the interface friction of typical concrete pavements was evaluated by performing a number of push-off tests. In this paper, reviews of classical friction theory and friction characteristics at the interface of concrete slabs and the underlying subbases are presented.
