Patent

CA 2200315

The present invention provides a stress absorbing composite for road repair that comprises a low stiffness geotextile, a viscoelastic material disposed over the low stiffness geotextile, and a high stiffness geotextile disposed over the viscoelastic material. Also provided is a method for retarding reflective cracking in an overlay using a stress absorbing composite and a repaired road containing a stress absorbing composite.

L'invention concerne un composite absorbant les contraintes et servant à réparer une route. Ce composite est constitué par un géotextile à rigidité limitée, par un matériau viscoélastique situé au-dessus du géotextile à rigidité limitée et par un géotextile à rigidité élevée situé au-dessus du matériau viscoélastique. Elle concerne également un procédé servant à retarder la fissuration par réflexion dans un revêtement au moyen d'un composite absorbant les contraintes, ainsi qu'une route réparée contenant un composite absorbant les contraintes.
