Opis:
This paper focuses on a better understanding of the process of reflective cracking propagation through the pavement structure. A series of finite element numerical simulations were conducted to investigate the initial stress and strain states in typical semi-rigid pavements with and without reflective cracks under traffic loading. It was assumed that reflective-cracks propagate from the base layer to the pavement surface. The influence of selected parameters, such as the load position, overlay thickness, and subgrade quality on stress and strain concentrations was investigated. The behaviour of the pavement structure under repeated traffic loading was analyzed in terms of ground compaction. The original theoretical model proposed by Prof. Andrzej Sawicki was used to predict the deformation of a pavement subgrade subjected to traffic loading. The damaging effect of cracks appearing in the pavement structure was investigated. It was found that even a single crack in the pavement structure may significantly reduce the pavement lifetime.

Opis:
Underground mining operations cause surface deformations which influence structures. A particular group of structures which are susceptible to the influence of mining operations are so-called “linear objects”, whose characteristic parameter is their length. Linear objects consist of, for example: roads, rails, sewers and water supply systems. Changes in the length of measurement bases (deformations) accompanying mining deformations and changes in ordinates, including the difference in subsidence (inclination), to a large extent determine the utility properties of the structures and create a significant nuisance when using them and even causing them to fail completely. It is worth emphasising that when applying proper preventive measures once continuous deformations have begun, it is possible to use the objects for a relatively long period of time. In the case of discontinuous deformations, the utility properties are significantly deteriorated, which most often leads to failures, significantly hastening the decision to conduct repair works. This article presents selected cases of the continuous influence of mining operations on a sewer system and of discontinuous deformations on a road pavement. The presented research and in situ observations may be useful in assessing, designing or re-building such structures in areas where mining operations are planned.
