Sand & Gravel Permeameter

  • Permeability in sands and gravels can help determine the drainage and porosity characteristics of materials.

  • This information aids in asphalt pavement design and placement.

  • The Permeameter conforms to ASTM D2434 for determining permeability of soils, sands & gravels by the constant head method.

  • Required equipment consists of a Permeameter, and a manometer panel to measure the flow-rate of water, a constant head tank to provide the water source, along with a stopwatch.

  • The inside of the cylinder at each port is machined out & lined with a #100 mesh stainless steel screen to prevent outward migration of fines during the test.

  • A spring inside the top is used to apply between 5-10 pounds of force against the top sample porous stone or screen.

  • This is to prevent material density changes during the test.4.5"Sand/Gravel Permeameter.
