Product Description

Digital Marshall Stability Tester Machine for maximum load and flow values of bituminous mixtures


The Marshall stability tester is mainly used to test the stability and flow value of asphalt mixtures. Asphalt mixture is a key material in road construction, and its performance directly affects the quality and service life of the road. Through Marshall stability testing, the mechanical properties of asphalt mixtures under specified pressure and deformation conditions can be determined, providing key data support for designing reasonable asphalt mixture formulations, evaluating their quality, and controlling road construction quality.

The marshall test is a proven method for determining the load and flow rate of asphalt elements. It starts with compaction into molds using either individuals or automatic Marshall Compactors, and is then conditioned in a water bath at the preset temperature. The Industrial Standard T0709-2011 and ASTM D6927 in TG E20-2011 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering are used to develop and manufacture the Digital Marshall Stability Tester Machine. Additionally, it is employed when testing bituminous materials for Marshall stability.

Features

1. The Marshall Testing Equipment includes stopwatch, automated test control, measurement calibration, and parameter setup features. The control unit will instantly assess the peak value and gather the sample's stability and flow values.
2. The stability, flow value, curves, outcome, and time are displayed on the LCD monitor.  The test effect is intuitive.
3. The device can hold 100 sets of test data and test time that can be called up as required. The entire process will be managed effortlessly.
4. A RS232 connection for transmission. Realize the higher computer's transmission. A PC can manage the data processing, storing, printing, and displaying. A PC can also be used to manage the evaluation processes.
5. The Marshall Testing Equipment also has functions for manual lifting, lowering and stopping. Convenient to use.
    
Ф100mm sample clamp is in standard accessory list for this instrument. Users can also select clamps as blow:
1. Sample clamp:   Ф150mm, one piece
2. Sample clamp:   Ф100mm and Ф150mm, one for each.
