Increased traffic frequency and axle loads combined with changes in pavement temperature exert stresses on asphalt pavements. These stresses induce the formation and propagation of cracks in the asphalt pavement, allowing precipitation and oxygen to penetrate into the underlying structure, thus accelerating the deterioration of bitumen binders. This results in cracked pavement layers and stripping of the asphalt surface.

TenCate® Geosynthetics pavement rehabilitation solutions such as Polyfelt® PGM and Polyfelt® PGM-G geotextiles address the demands of both large-scale highway projects as well as smaller residential projects. Our interlayer products provide solutions to the most common problems of maximizing maintenance cost, improving ride quality and reducing pavement deterioration.

Keeping the existing road pavement inventory in a serviceable condition is one of the major challenges of road authorities world-wide. Therefore, the focus of attention is on maintenance techniques and rehabilitation methods which allow the working life of the basic road structure to be extended in a cost effective and technically reliable manner.

One method which has been successfully used world-wide for more than 30 years is the maintenance of asphalt and concrete roads using paving interlayers. This method represents an economical means of considerably increasing the maintenance intervals and thus the working life of the road.
