Numerical Analysis of Fiber-Reinforced Whitetopping Pavement Under Wheel Loading
Ultra-thin Whitetopping (WT) is a technology in which a thickness of less than 100 mm of high early strength concrete pavement overlay is laid on a distressed bituminous pavement as a rehabilitation measure. WT modified by the application of Fiber-Reinforced Concrete (FRC) is adopted in this study. The three-dimensional finite element modeling developed in this study is for four-layered pavement with top fiber-reinforced WT layer, second bituminous layer, third sub-base, and bottom subgrade layer. Thickness and material properties of fiber-reinforced WT layer and bituminous layer are also varied for the parametric study. Loading is applied as per IRC:58-2015 and IRC:6-2010. Three different loading conditions such as interior, corner, and edge are considered, and maximum deflections at those loading positions are found out. The effect of temperature differentials is also studied. It is found that the deflection of fiber-reinforced WT pavement is maximum at slab corner, and it should be 5–10% times higher than edge and interior loading.
