there is described a method for road surface marking with tape material , including the steps of forming an essentially bituminous primer layer on such surface and then pressingly laying a prefabricated tape material on said primer layer , such layer being formed with an essentially adhesive composition having a relatively low viscosity when contacted with the road surface and comprising a substantial percentage of cross - linkable components at least part of which is hydrophilous . the layer is capable of attaining within a few minutes a viscosity of about 10 5 cp and then further hardening to provide a final resistance to horizontal stresses applied to the tape material of at least 3 kg / cm 2 . there also are described devices for promoting cross - linking by preforming pre - polymers of a two - component reactive composition .
