Marshall Stability Test Apparatus LWD

Item Code:LWD Features:
  • Description
  • Main Specifications
  • Accessories
The Apparatus is used to test the thermal stability and capability of resist-plasticity deformation of bituminous mixture material and flow value to provide accurate basis for the composition of bituminous mixture material. Based on LWD-1, LWD-2 is with load and displacement transducer as well as micro-processing technology, carrying out control during the test and data acquisition and processing, at last, it will save flow value of the biggest stability and stability. It can automatically increase load and automatically draw up the relationship curve between the load and deformation. It is suitable for traffic engineering, university and research institute to do the experiment etc.
