Research on geogrids in asphalt pavements

Due to the increased load (cargo weight) per truck axle, the introduction of super-single tyres, the continuously growing traffic numbers and the political difficulties to achieve widening of roads, the individual layers of pavement structures are degrading at a faster rate, while there is in fact no time frame left to do structural maintenance. Also there is the desire that pavements should last longer and when a maintenance treatment on a specific jobsite is necessary, it should be carried out in a short(er) period of time. Furthermore, maintenance intervals for pavements should become more accurately predictable, so they can be planned better in combination with other works on for instance bridges, safety barriers, dynamic traffic management infrastructure, etc. With respect to rural roads, it has become clear that because of the reduced budgets more cost-effective ways to upgrade pavements are needed. From the foregoing it can be concluded that there is a clear need for reliable, robust and cost effective (structural) maintenance technologies for roads. The (right) use of grids in asphalt layers can certainly meet this demand.
