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 105 cp and then further hardening to provide a final resistance to horizontal stresses applied to the tape material of at least 3 kg/cm2. There also are described devices for promoting cross-linking by preforming pre-polymers of a two-component reactive composition. |
