Abstract: Most highway and airport rigid pavements constructed today consist of a subbase layer, giving rise to a system of a concrete slab supported on a two-layer foundation. This paper makes use of the solution of a slab on a ...

Abstract: This paper describes the development of a solution of surface deflections for the problem of infinite-slab-on-elastic foundation and its use in back-calculation analysis. Numerical integration is employed to compute the ...

Abstract: This paper presents a new procedure for back-calculating the properties of a concrete pavement with two slab layers using deflection measurements from nondestructive deflection testing. The two slab layers are first ...

Abstract: The wear of aluminum alloy may be decreased by its reinforcement with quasicrystals (QCs) prepared by melt, which in itself has good wear-resisting properties. This research paper considers the part played by a dense ...
