Outstanding efficiency as a decisive factor
Paving at such extreme widths and efficient, high-quality compaction are a logistically and technically challenging proposition. The construction contractor, Jincheng Luchuang Asphalt Application Co., Ltd., left nothing to chance when planning the project. After a thorough analysis of all available machine technologies, the contractor picked out the two Wirtgen Group machines. Their exceptional efficiency was the main factor that swung the decision in their favour. The SUPER 2180-3 Li, for instance, is specially designed for high paving performance. Amongst other features, its efficient material management and the particularly high capacity of its material hopper made it the ideal choice for the project. The hopper boasts a capacity of 15 t and thus guarantees the rapid transfer of asphalt mix from tipper trucks and contributes to an uninterrupted paving process.
Paver with a fixed width screed for large paving widths
The impressive qualities of the SUPER 2180-3 Li Highway Class paver and the SB 300 TV fixed width screed become particularly clear when paving extreme widths. This was also the case on the highway construction project in Shanxi: The Vögele paver paved the 6 cm surface layer of asphalt concrete at a laydown rate of 2 to 4 m/min – an impressive figure, considering the extreme paving width of 11 to 12.5 m. With the fixed-width screed, the paving crew achieved an even and seamless, high-quality paving result across the entire width. In the course of this, the SB 300 delivered not only high paving performance, but also maximum flexibility and efficiency: Thanks to the extra-wide hydraulic bolt-on extensions, the width of the screed can be hydraulically varied by up to 2.5 m. In view of the varying working widths in Shanxi, this was particularly practical and time-saving, as it was unnecessary to install or remove any bolt-on extensions on the fixed width screed. The operator was able to simply vary the width with the SmartWheel function on the screed control console.
