Digital Marshall Stability Test Apparatus
Model No.: SET-1327
Civil Lab Equipment Manufacturer is a leading manufacturer and supplier of Digital Marshall Stability Test Apparatus. The machine is priced reasonably and has been manufactured in sync with international quality standards. Our range of test apparatus offers excellent performance and meets the requirements of the clients quite perfectly.
The Marshall Stability Test Equipment is mainly used for determining the stability of the bituminous samples that are used by contractors, laboratories and government agencies. The equipment is specifically designed to measure the resistance of the plastic flow of the cylindrical specimen for the bituminous paving of the loaded mixture on a flat surface.
The test samples and made available and is tested at a speed which is approximately 50.8mm/mi. The highest load (stability) along with the deformation, i.e. flow, of the sample is recorded with the help of digital indicator along with S type load cell and 25mm LVDT. Normally, the test is suitable for hot mixing designs with the help of maximum size bitumen and aggregate of highest size, i.e. 25mm. The machine is specifically used for the purpose of evaluating and fabricating the bituminous paving mixes.
