Conventional rigid pavement on soft soil needs more thickness of slab which increases self weight, and it is unbeneficial for soft soils. The pavement of Nailed-slab System has been proposed by previous researcher as an alternative solution for pavement on soft soils. This system is not a soil improvement method, but rather as an alternative method to improve the performance of rigid pavement on soft soils. The installed piles under the slab were functioned as slab stiffeners. This paper is aimed to inform the performance of Nailed-slab System on soft clay, its consideration forprospect of practical application, and designing method.The full scale Nailed-slab System was conducted by Puri (2015a) on soft clay which consisted of 6.00 m x 3.54 m slab area with 0.15 m in slab thickness, 15 short micro piles (0.20 m in diameter, 1.50 m in length, and 1.20 m in pile spacing) as slab stiffeners which installed under slab. Piles and slab were connected monolithically, then in due with vertical concrete wall barrier on the two ends of slab. The system was loaded by vertical monotonic and repetitive loadings. One pile row Nailed-slab was also conducted and tested by compression and pull out loadings. Results show that the installed piles under the slab which embedded into the soils were functioned as slab stiffeners and were able to response similarly in 3D. Observed differential settlements were very small. This system has higher resistance due to vibration. Good performance was also shown by this system due to uplift load, as well as swelling pressures of expansive soils. Thereby, the Nailed-slab system is promising for practical application. Hence, it is needed conducting of a field trial on a road section laid over soft clay or expansive soil.
