Laboratory Asphalt Permeameters

Description

Asphalt Permeameters

STANDARDS  : FM 5-565

Laboratory Asphalt Permeameters measure the hydraulic conductivity of saturated 6in (152mm) diameter asphalt cores or laboratory-compacted specimens using

the falling head method.

The simple, easy-to-use method is based on procedures developed at the Florida DOT.

A version for 4in (102mm) test specimens is also available but does not meet the sample size requirements for the test method.

An asphalt sample is secured by expanding discs inside a cylinder lined with a replaceable latex membrane.

A self-contained manual pump provides a vacuum to draw the membrane against the cylinder during sample placement, as well as pressurizes the membrane during testing

to fill voids and eliminate flow down the outside of the specimen.

A dial gauge displays pressure applied by the hand pump.

Permeability of the prepared specimen is determined by the timing flow of water from the included 500cc Manometer through the sample
