Asphalt Mixture Maximum Theoretical Relative Density Tester With Microprocessor Control

Description

The asphalt mixture maximum theoretical relative density meter is used to test he asphalt mixture theoretical relative density thus to provide reference for asphalt mixture match ratio design, road condition survey, road construction management avoid ratio and compaction degree calculation, it’s kind of common asphalt testing equipment.

Noted: it can’t test porosity asphalt aggregate whose absorption over than 3%.
