Asphalt in-situ permeameters measure one of the fundamental characteristics of porous asphalt (or draining asphalt), basically its capacity to allow water to drain through the asphalt and onto the lower layers, improving the friction characteristics of the road and reducing road spray. A range of asphalt permeameters, complying with various international standards, is available in this section.
For measuring the water percolation time through the draining pavements. The apparatus comprises a graduated transparent cylinder, a metal support, a rubber gasket and a 20 kg counterweight with handles.
