Compactasphalt, developed by Dynapac, allows the simultaneous laying of two different layers in a single pass. Both the upper asphalt layers – the wearing and binder courses – are laid and compacted simultaneously ‘hot-on-hot.’ As a result, the new concept provides a better interlocking of the two courses, ensuring increased life expectancy, higher deformation resistance, and lower maintenance costs.
Compactasphalt features a paver with two separate material hoppers for both asphalt mixes, and a special unit to convey the wear course material to a second screed.
The hopper for the lower layer – generally the binder – has a capacity of 45 t. The hopper for the wearing course holds 27 t. The use of mobile feeders allows a continuous movement of the paver, improving the surface evenness.
