Rigid pavement with Nailed-slab system is a development of the chicken claw method that changes the pavement shell of the chicken claw system with short piles. One of the most important things in designing rigid pavements with a Nailed-slab system is lateral and eccentric loads. This study aims to determine the influence of lateral and axial loads on the behavior of pavement slabs, including the influence of gaps due to lateral loads on the bearing capacity of pillars and the deflection of pavement slabs on Demak soft soils. The results showed that Demak soft soil had a shear strength of 21.4 kPa with a moisture content of 33.1% with a fine grain dominance of 93.2%. The rigid-slab system exhibits significant initial deflection and shift due to the presence of eccentric and lateral axial loads, but still achieves stability within safe limits for applications in Demak soft soils. The gaps that occur due to lateral loads cause significant pile shifts at the beginning of the phase, reducing temporary bearing capacity and increasing slab deflection. However, the pavement structure remains stable after reaching a gradual shift pattern.
