1 Scope
This document specifies a test method to determine the resistance of bituminous materials to de-icing
fluids. The procedure determines the surface tensile strength of a specimen of asphalt which has been
stored in de-icing fluid.
This document is primarily used as a test on asphalt to be laid on airfields, but it can be used for asphalt
to be laid on roads or other paved areas.

surface tensile strength
tensile stress at maximum force when testing according to this test method
4 Principle
Testing is performed on a sawn cylindrical specimen of asphalt on which a well-defined test surface has
been drilled out in the bituminous mixture to a depth of about 5 mm. A steel plate is bonded to the test
surface of each specimen in turn. Four specimens are stored and four are not stored in a de-icing fluid.
During testing, the plate is pulled off with a tensile force increasing at a rate of 200 N/s, the force being
applied perpendicular to the test specimen surface. The tensile force at
