OEM Asphalt Marshall Compression Machine Automatic Marshall Stability Tester Manufacturers, Supplier

Used for Marshall stability test and water-immersion Marshall stability test to design the mix ratio of asphalt mixture or inspect the quality of asphalt pavement construction. The water-immersion Marshall stability test (vacuum saturated water Marshall test can also be performed as needed) is used to test the ability of asphalt mixture to resist peeling when damaged by water, and to test the possibility of mix ratio design by testing its water stability.

Used to determine the thermal stability and resistance to plastic deformation of asphalt mixture - stability and flow value. Provide accurate basis for the composition and mix ratio design of asphalt mixture. Can measure stability and flow value.

Product Description

Instrument Composition

The system is a comprehensive testing solution which includes the host, force measuring device, flow value measuring device, printing device, and related accessories. The host is designed for versatility, capable of completing various vertical load tests with minor adjustments and specific accessory equipment.

Performance Characteristics

1. Automatic Function

Fully automated capabilities for loading, stopping, and data display. It can collect data, judge peak values, hold them, and print both data and analytical curves.

2. Circuit Design

Advanced design featuring separation of strong and weak currents, as well as digital and analog signals. Industrial-grade electronic components ensure stable performance and strong anti-interference across wide temperature ranges.

3. Protection Function

Precautions for Use

The power ground wire must be grounded separately. Ensure pressure and flow sensor plugs are connected correctly.
For unstable voltages or power grid interference, use an AC purification power supply or voltage stabilizer.
Avoid stressing the load control and printer cables. Do not share power sockets with high-power appliances.
Store the instrument in a dry area. In humid environments, keep sensors in a drying box to maintain precision.
