NBN EN 12697-20:2004

The indentation test serves to determine the depth of indentation, and thus to test the behaviour of mastic asphalt, rolled and other such asphalts, when force is applied to them via a cylindrical indentor pin with a circular flat-ended base. Mastic asphalt as described in prEN ((WI 00227009)-6) for road construction, in prEN ((CEN/TC 303WICCCC)-2) for floor screeds and in prEN (WI 31407) for waterproofing in building and engineering constructions can be tested following the test method prescribed hereafter. The maximum nominal size of the aggregates in the mix is up to and including 16 mm.
