Rehabilitation treatments applied to a local road prone to terrain subsidence from mining excavation should be designed considering cost-efficient and effective reinforcement solutions. In the analysed case, a glass-fibre mesh was applied under asphalt concrete layers in 2008, in one lane while another was left without the reinforcement. The main objective of this paper was to investigate the effectiveness of reinforcement by analysing the amount of produced on the pavement and the influence on pavement deflection. It was found that the reinforcement retracted the number of cracks, however, did not affect the bearing capacity. The influence of the applied geosynthetic was manifested in the values of the radius of curvature. The overall technical state of the road requires immediate treatment and the applied reinforcement proved obsolete because in this particular case of road located in the mining active terrain the glass fiber mesh did not prolong the life of the pavement.

Construction is one of the industrial sectors responsible for the use of large quantities of natural raw materials. This fact makes it necessary to look for new technologies of producing construction materials based as much as possible on waste materials. Such a solution could have positive effects on the environment and reduce construction costs. This paper presents the results of a study on the deformability of a mix made from anthropogenic waste combined with a hydraulic binder. The presented mixes consist of unburnt coal mining slates (mine waste), shredded rubber waste, silica fly ash and CEM I 42.5 R cement. Samples with two different contents of shredded rubber waste 0% and 10% were made from the mixtures and subjected to destructive compressive strength testing. The strength testwas combined with sample deformation measurement performed with the Aramis 3D Video Correlation System. The results presented show the effect of the shredded rubber waste content on the deformability of the sample.
