Bituminous Mixtures Theoretical Maximum Specific Gravity Tester
Description
Application Range:
The instrument is suitable to determine the theoretical maximum relative density of asphalt mixture by vacuum method, and is used to calculate porosity and compaction for asphalt mixture ratio design, road condition investigation or road construction quality management.
Application EXCLUDES determine of asphalt mixtures with porous aggregates with water absorption rate more than 3%.
Referring to standard of T0711-2011 and ASTM D2041
