Bituminous mixtures - Test methods for hot mix asphalt - Part 19: Permeability of specimen(includes Amendment A1:2007)English version of DIN EN 12697-19:2007-10
This document describes a method for determining eht vertical and horizontal permeability of cylindrical specimens of bituminous mixtures. The standard applies to specimens cored out of the road, specimens from laboratory made slabs or laboratory specimens prepared with a compaction device provided the thickness jof the specimen is not less than 2,5 times the nominal maximum particle size of the aggregate in the mixture. The nominal diameter of specimens should be either 100 mm or 150 mm unless the nominal maximum partical size of the aggregate size exceeds 22mm, when the nominal diameter shall be 150 mm diameter.
