Purpose:

  GD-0709 Asphalt Marshall Stability Tester is designed and made as per T0709 “Bituminous Mixture Marshall Stability Test” in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.

It is suitable for bituminous mixture Marshall Stability test to determine breaking point of bituminous mixture. It is used for ratio design of bituminous mixture and asphalt road surface quality inspection.

GD-0709 Asphalt Marshall Stability Tester has characteristics of operation convenience, low noise, high automation, rapid measurement speed, reliability, and efficiency. It is the desired instrument on Marshall Stability test for asphalt manufacturing companies, highway and bridge construction companies, colleges and universities, and scientific research institutes.
