Germans laid yellow asphalt for a dash of colour

Indeed, yellow coloured asphalt is gaining in popularity nearly everywhere. On an ever growing number of job sites, urban planners are going for that bright touch in path construction, as was the case for two combined foot and cycle paths built in a residential area in Delitzsch.
The contract for paths 160m and 250m long, was awarded to contractor Ezel Torgau GmbH. Although for the surfacing of the paths, a special coloured mix was to be laid, work began as with any conventional path. Torgau’s paving team used a Super 1800-2 to place a base course, bonded with black bitumen as usual, between the previously installed kerbstones.
In Delitzsch, it laid an 80mm deep base course 4m wide, and its AB 500-2 extending screed in TP1 version, achieved a high degree of precompaction. As a mix, TS 0/22 C 70/100 RC was used.
Yellow surfacing
Once the base course had been placed, the paver would usually have needed thorough cleaning in order not to soil the yellow surface course mix, and produce an absolutely clean final result. It was a lucky coincidence that just at that time, the contractor took delivery of a brand-new Super 1303-2 from Vgele’s compact equipment class. So this machine, sparkling with cleanliness, was put straight to the task of paving the yellow surfacing.
It placed the yellow mix type Deucolor W Sabbia i8 without a hitch. Ezel Torgau’s paving team, laid the coloured surfacing on the combined foot and cycle paths to a width of 4m. “Even we were surprised at just how smoothly everything went. From supply of the paver with mix through to paving and compacting, everything went as usual,” reported Stephan Portsch, the contractor’s job site manager.
The AB 340 TV extending screed, mounted on the Super 1303-2, achieved an excellent degree of precompaction with tamper and vibrators.
No training required
The paving team easily got to grips with its brand-new paver right from the start. This was due to ErgoPlus®, the innovative operating concept installed on all dash 2 generation Vgele pavers. For teams already familiar with a paver of the current generation, there is no need for extra instructions or training.
Finally, a Hamm DV 40 VV vibratory roller, thoroughly cleaned and spick and span, produced the final asphalt density. The machine was equipped with intelligent Hammtronic Technology, which optimises machine functions, and as a result, provides economical operations and increased productivity.
Highly satisfied
The town planners of Delitzsch were highly satisfied with the paving result. “That the coloured asphalt could be paved in such outstanding quality was great. The yellow paths have exactly the appearance we imagined at the planning stage,” said Ms Richter, a member of the civil engineering department of Delitzsch.
