Abstract

The paper presents the research in laboratory conditions and the analysis of the benefits that could be brought by the transfer into the road repairs of the technological concept currently used in the field of civil and industrial constructions for buildings repairs and consolidations, namely the guniting procedure. We analyzed the influence of the deposition under pressure of the asphalt mixture layer, in order to highlight if further compaction, vibration and jointing operations are needed, which would increase the costs of the works. The results are gratifying and we bring this procedure to the attention of the road maintenance authorities, as it has similar results to the current procedures, but with low costs.
