AccuFoamer - Laboratory Bitumen Foaming System


The new AccuFoamer from D&H Equipment, Ltd. is ideal for repeatable batching of foamed asphalt samples in the laboratory. AccuFoamer is designed to fit on a laboratory counter top and can easily be used to check the proper ratio of bitumen to additive used in Warm Mix Asphalt (WMA) for variety of different conditions. The unit includes pressurized reservoirs for bitumen and liquid additives (water or other chemicals) and can accurately batch 150 to 6800 grams through the mixing chamber.


  • Accurate foaming device in a small and compact design.
  • The AccuFoamer System costs thousands less than much larger foaming devices.
  • Evaluate asphalt binder prior to production and not during.
  • The foaming system allows users to evaluate changes to the absorption of the aggregate in the mix design stage.
  • The AccuFoamer allows the user to optimize the mixture by adding and evaluating the interaction of other additives with the mix.


  • Bitumen Chamber heated accurately up to 200°C (390°F)
  • Can heat additive to 82°C (180°F)
  • Accurate and repeatable adjustment of liquid additives from 0 to 9%
  • Bitumen and additive volumes controlled by air pressure
  • Expels foamed mixture into sample container or directly into mixing bucket
