Custom Low Temperature Storage Asphalt Stability Testing Machine Manufacturers, Supplier

The modified asphalt storage stability tester mainly simulates the actual situation of storage stability of various properties of asphalt, considering the influence of factors such as volume, temperature, and rotation speed on the storage stability of various properties of asphalt. The asphalt storage stability testing machine can effectively evaluate the stability of various properties of asphalt during low-temperature storage, as well as the influence of storage conditions on the quality of modified asphalt during storage. It can automatically control temperature, adjust speed and stir, and use nitrogen atmosphere to eliminate the oxidation of modified asphalt or asphalt during storage, so as to better simulate the on-site conditions and make the index test more representative.

Product Description

Working Principle

Generally, the modified asphalt sample is placed in a specific container (such as an aluminum metal tube), heated to a specified temperature and maintained for a certain period of time, so that the modified asphalt undergoes a storage process at high temperature, and then observes and detects the performance difference between the upper and lower parts of the sample, such as the difference in softening point, to judge the storage stability of the modified asphalt.

Structural Composition

  • Heating system: Composed of a heating furnace, heating wire, etc., which can make the sample evenly heated at a set temperature.
  • Temperature control system: Including temperature sensors, controllers, etc., which can accurately control and display the heating temperature to ensure temperature stability.
  • Sample container: Usually an aluminum metal tube that meets the standard requirements, with a suitable height-to-diameter ratio, which is convenient for sample loading and unloading and test operation.
  • Brackets and fixtures: Used to support and fix the sample container to ensure the stability of the container during the test.
