The behavior of grids and nets in asphalt pavement

Abstract

In this article, we want to clarify conceptual confusions about grids and nets applying in asphalt pavements structures, define the repairing and -in some cases- damaging effect of grid usage. The biggest question in reinforcement 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 and master curve of the structure. The computer limited number model 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. © Periodica polytechnica 2011.
