The N614 Runs NE from the River Meuse town of Amay to near the medieval town of Tongeren across the Belgian lowlands west of Liege. This long straight Roman Road receives heavy traffic, placing stress on the sub layers below the asphalt. The Belgian Roads and Traffic Administration (AWV) who monitor the road, noted severe damage of a 2.7km length caused by reflective cracking, especially where transverse cracks were forming at the end of the concrete slabs which made up the sub surface pavement.
Replacing the pavement would have been prohibitive and the administration were looking for a surface reinforcing solution to reduce this movement. AWV were attracted to the stiffness and robustness of the steel Fortifix product which is able to control lateral movements between the slabs. In addition Jan van Gestel (Project Manager AWV) commented “The interlayer performs best when laying perfectly smooth. While synthetic meshes can shift, Fortifix® rolls out evenly onto the road surface and adheres perfectly to the elastomer emulsion. The magnetic properties of the steel enables separation from the asphalt, making the materials 100% recyclable. What gave us the reassurance to try out Fortifix® is the fact the product had already been added to the standard specification documents. Fortifix® has been thoroughly investigated during the R&D phase and also the OCW (the Research Center for Road Construction) had given its approval.”
The ABG Service ABG are able to give specific advice on the application for this type of asphalt reinforcement and provide an installation service along with the supply of the Fortifix steel cord rolls.
ABG are official UK distributors of Fortifix® steel-based solution to road cracking manufactured by Bekaert.
Jan van Gestel (Project Manager AWV) “ The biggest challenge for this project was to choose a reinforcement solution that adheres perfectly to the milled surface of the road, but which can still be easily removed and recycled when the time finally comes that the road needs to be completely renewed. In this case, in about ten years.”
