Abstract

vement on soft soils. This system consists of a thin reinforced concrete slab, and short piles attached underneath. The installed piles under the slab were functioned as slab stiffeners and anchors. This research is aimed to learn the deflection behavior of Nailed-slab System by conducting full scale testing model. The tested full scale model was 6.00 m x 3.54 m slab area with 0.15 m in slab thickness, and consists of 15 short micro piles (0.20 m in diameter, 1.50 m in length, and 1.20 m A new kind of rigid pavement is Nailed-slab System. It is not a soil improvement method, but rather as an alternative method to improve the performance of rigid pavement on soft soils.

Nevertheless, the testing results show good performance. The model experienced very small deflection and has higher bearing capacity above 160 kN because of the linear elastic-response is kept until load 160 kN. Loading position was not significantly influenced to the maximum deflection and bearing capacity. Differential settlement due to monotonic loadings tend higher than the one caused by repetitive loadings for interior loading. All total and differential settlements were smaller than allowable deflections.
