In order to solve the problems of asphalt pavement cracks, deformation, granule peeling and other diseases, Dynapac has proposed an innovation in the construction of asphalt pavement: composite asphalt mixture surface layer, and the double paver is exactly this idea. Results. The machine will layer the two layers of the two different asphalt mixtures in one layer with a double paver. The difference from the traditional 4cm surface paving is that the surface layer is reduced to only 2cm.
This new paver is a composite because it contains the overall structure and technical components of the upper paver and its own energy supply system. In addition to the screw conveyor, the screw conveyor replaces the scraper conveyor on the conventional paver and transports the mix from the elevated upper hopper to the paving slab. This component is trailer-style and can be contracted as the paver walks. In addition, since the asphalt mixture of different compositions is simultaneously paved to produce a thick asphalt mixture laminate, it will cool very slowly and utilize the waste heat of the next layer.
