CONCRETE PAVING

Mobile road construction plant When paving in inset application, the concrete is delivered by trucks and dumped ahead of the slipform paver. It is spread by an excavator or second paver when working with large paving widths. Depending on the paver model used, the material is then distributed evenly across the full paving width by a spreading auger or spreading plough. The robust paving mould slipforms the concrete pavement while travelling over the previously distributed concrete material. Electrical vibrators emitting high-frequency vibrations ensure optimum compaction of the concrete during the slipforming process. Tie bars and dowel bars are inserted into the freshly paved concrete automatically. Last but not least, a finishing beam and super-smoother put the finishing touches to the new pavement.

Optimal structure and protection of concrete surfaces Travelling on concrete pavements produces noise of different levels and frequencies, depending on the surface texture. Self-propelled texture curing machines are capable of giving concrete surfaces the desired surface texture by applying a broom that lightly brushes the surface. A dispersion is additionally spread on the concrete surface by the integrated spraying system. It prevents premature drying of the concrete surface and edges.
