AN 164 ACCUPYC ASFALTO

Asphalt Density Using AccuPyc II TEC

Measuring asphalt density per ASTM Test Method D70-09 requires the use of a glass pycnometer and very tedious analysis conditions. Using this ASTM method as a guide, the density of asphalt is measured using an AccuPyc II TEC and 3.3-cc disposable aluminum cups. The density results of four different asphalt samples using the AccuPyc are compared to results obtained by a third party using the ASTM glass pycnometer method. Results from the two methods ranged from a 0.003% to 0.026% difference.
