Voegele sets paving record

摘要

Using material transfer vehicles (MTVs) can play a major role in delivering high quality road surfaces. These units can help boost quality by minimising the risk of material or thermal segregation. A major road paving project has been carried out in Germany using innovative paving methods. For the first time ever, binder and surface courses were paved over a width of 15.5m. This paving job was carried out on a 4.2km stretch of the busy A10 Autobahn ring road around Germany's capital Berlin. The tenders were called for by the German Federal Ministry of Transport, which specified jointless paving over the full 15.5m road width so eliminating potential problems of freeze thaw cracking originating from the joints, a major cause of early road surface failure. The aims of the project were to prove that high paving quality can be achieved over large widths and show that the temperature of the asphalt mix could be maintained from the asphalt plant to paving work.
