NCAT Field Asphalt Permeameter Kit

    NCAT Field Asphalt Permeameter Kit

    $0.73

    The NCAT Field Asphalt Permeameter Kit was selected by the National Center for Asphalt Technology (NCAT) for its close correlation with laboratory test results. This falling-head permeameter uses Darcy’s Law to determine the rate of water flow through asphalt pavement. The unit permits accurate, on-site estimation of permeability, eliminating the need for coring, patching, and laboratory testing. Corrections to mix and placement procedures can be implemented right away and testing can be completed in just 10—15 minutes by one technician, with no extensive training necessary.

    The 4-tiered graduated standpipe is supplied in two sections and constructed of rugged plastic. A sealing material is placed on the base plate and the unit is positioned on the test site and seated against the pavement using gentle foot pressure and included base weights. After filling with water, the outflow is observed against the clearly marked graduations and timed. The uppermost tier allows rapid determinations in low-porosity pavements. The larger diameter tiers offer enough time to accurately read flow on more porous pavements. An alternate top section is included to replace the two top tiers with one larger diameter tier for extended test times on moderately permeable mats or for rapid filling when testing highly permeable mixes.

    The Kit includes the 4-tiered Permeameter, Alternate top section, Filling Tube, a package of Moldable Sealant material, Whisk Broom for test site preparation, and four 5lb (2.3kg) Base Weights. The kit is packaged in a convenient carrying case.
