Pavement rehabilitation by using an asphalt reinforcement grid made of high modulus polyester
The rehabilitation of an existing cracked pavement made of concrete slabs or asphalt can be simply done by the installation of new asphalt layers. Due to external forces from traffic and natural temperature variations, existing cracks or joints rapidly propagate out of the old pavement into the new asphalt overlay. The application of an asphalt reinforcement showed excellent results in delaying the development of reflective cracks. The installation of a high modulus polyester grid led to a considerable extension of pavement life. This paper shows typical applications and limits for the use of asphalt reinforcement in rehabilitating deteriorated pavements. This will be described through basic theory, results of laboratory investigations and our practical experiences from the last 40 years with asphalt reinforcement.
