Abstract

A proposed alternative solution for rigid pavement problem on soft soil is the pavement of Nailed-slab System. It is a kind of developing the rigid pavement. Equivalent modulus of subgrade reaction (k’) can be used to analyze Nailed-slab System. This modulus consists of the modulus of subgrade reaction from plate load test (k) and additional modulus of subgrade reaction due to pile installing (∆k). The ∆k can also be determined by using the curve of the displacement factor. This research is aimed to validate the theory of additional modulus of subgrade reaction by using the curve of displacement factor due to the results of a prototype test of Nailed-slab with 1 pile row. The prototypes were constructed on soft clay and the connection between pile and slab was perfect monolithically. These systems were loaded by monotonic loads. Calculated deflections based on the method of the additional modulus of subgrade reaction were compared to the observed deflection and the results from the Finite Element Method. The result shows in good agreement with the observation. The proposed method of analysis was practical in use and timeless consuming. Designing the Nailed-slab by considering a single pile row which used k’ will result in design in the safety zone.
