•   In the last few years asphalt grids and nets have been used in enormous amount in Hungarian road construction, without any overall laboratory researches. In this article, we want to clarify conceptual confusions about grids and nets, define the repairing and--in some cases--damaging effect of grid usage. The biggest question in fortification of pavement, is the possibility of mixture of grid and net with the asphalt layer below. To observe these attributes we used the method used at bridge lining: slide method. Small and large wheel observations have been made to research track appearances in fortified construction. The lifetime of the construction have been observed by a fatigue method: the standard four point bending method. The computer limited number models have been used to prove fatigue results, and with the adequate material model development used at different type of asphalts showed how gross asphalt can be replaced by the nets and grids usage.
