The Impact of Changes in the Designs of Concrete Airport Pavement on Its Strength Properties
Journal Title: Machine Dynamics Problems - Year 2018, Vol 42, Issue 1
Abstract
The article presents the analysis of dowelled slabs made of reinforced concrete which were subjected to thermal and operational loads, in the aspect of varying diameter of the dowels and their arrangement. The main object of the study was to present a stress-strength analysis of a fragment of a concrete airport pavement composed of a system of four identical slabs with dimensions of 5m x 5m and 0.3m thickness which were dowelled with one another. Using modifications of both the diameters of the dowels and their spacing, a detailed assessment of the state of stresses and displacements was made both in selected portions of airport concrete slabs and in dowels themselves using the finite element method. Using certain variants of dowel settings and diameters, an assessment was made as to the selection of optimum parameters for concrete airport pavement designs.
