Road construction with SUPER 800 Mini Class paver

When also used to pave coloured asphalt, the modern tracked paver showcases its skills as a landscape architect: apart from its striking appearance, with many different shades to choose from, coloured asphalt also offers key advantages over the coloured coatings which are sometimes employed – for instance, instead of becoming slippery, it retains its grip even when wet, thus enhancing safety.

Since contracts involving coloured asphalt are relatively few and far between, many contractors are naturally wary of processing the material. Of course a number of details must be kept in mind when producing the asphalt, particularly concerning the careful selection and coordination of the materials, but once on the job site the process itself is conventional: mix lorries deliver the material right into the material hopper of the SUPER 800.

The large material hopper with separately folding sides is designed so that the machine can always be supplied with paving material in the best, most cost-effective way. This allows material to be fed even if the feed vehicle is unable to dock centrally in front of the machine, such as when paving along walls, for instance.

There is a very important difference when paving coloured asphalt, however: the asphalt mixing plant, the feed lorry and of course the construction machinery used must be cleaned thoroughly beforehand so that the coloured asphalt is not contaminated. “We won this contract in a bidding process. The fact that our company produces, delivers and paves the asphalt itself meant that we were able to prepare the entire supply chain perfectly for the red material,” said Li Limin. “Aside from the fact that it cools a little quicker than conventional mixes, it behaves normally,” Li added. To ensure that the material always arrived on the job site quickly, Shandong Hongyu Construction Engineering Co., Ltd. made sure it had enough lorries from its fleet in operation at all times.
