The paper deals with investigation and analysis of strength characteristics development of cement stabilized courses made from mine refuse materials from Rudnany. Cement stabilized courses made from the material from the dump Patoraka (graphite) - Rudnany B and the dump Zimna (diabases) - Rudnany C underwent a long-term investigation by destructive and non-destructive methods. Long-term investigation were carried out on testing beams (10x10x40) cm3 in laboratory conditions.From the reported results follows that the investigated materials are suitable for the pavement foundation of roads. It is also obvious that for the investigated cement stabilized courses, for which the mixture composition is known and which were treated in the same way, it is possible to determine working characteristics with required accuracy and as a consequence to predict the development of strength characteristics of these mine refuse materials. When the cement stabilized courses are built in the pavement foundation of roads and highways, the asphalt layer are laid upon them after some time and the roads are opened to traffic. This raises the question about the way in which the strength increasing in time influences the service life of roads and whether this process results in the formation of shrinking cracks in the cement stabilized courses which are copied in the wearing course. At the implementation of cement stabilized course in the pavement foundation of a road it is therefore necessary to include in the technological process of road construction also treatment of these courses until the asphalt layers are laid upon them. |
