Abstract

The Nailed-slab Pavement System was proposed as an alternative improving for rigid pavement performance on soft soils. Puri, et.al. (2012a) proposed a new approach for practical purpose in designing where pile friction resistance is fully mobilized and the tolerable settlement is considered. The additional modulus of subgrade reaction due to pile installing is defined by using safety factor 2.5. Effect of variation in safety factors (SF) were not considered yet. In this paper, effect of SF variation due to slab deflection will be considered by using SF 1.0 to 3.0. The slab deflection will be calculated by using beam on elastic foundation theory. Analysis will use data of loading test on 1-pile row full scale Nailed-slab by Puri, et.al. (2013). Observed deflection data will be used to determine the additional modulus of subgrade reaction. Calculated deflection based on the additional modulus of subgrade reaction is compared to the observed deflection. Results show that SF variation affects the calculated deflections. Good results are obtained in the sense that the calculated settlement is in good agreement with observation. The SF = 1.0 is adequate for analysis. The Nailed-slab in the field will have extensive area and alot of number of installed pile under the slab. Hence, the performance of this system would be better due to reduction on the slab deflection.
