The Nailed-slab System is a new proposed method to solve the problem of rigid pavement on soft soils.
In this paper, Nailed-slab model tests were conducted to learn the behavior of this system. The models are
presented as strip section of rigid pavement on soft clay and consist of concrete slab, short friction piles
which installed under the slab, and vertical wall barrier at the end of slab. The models were loaded by
repetitive loadings. Tests result will be compared to the calculated deflection by using Finite Element
analysis. Further discussion about the comparison of slab deflection related to vertical wall barrier under
repetitive loadings will be presented.
