REJUVE

Rejuvenating porous asphalt


REJUVE

The winter months in Europe can be damaging for road surfaces, as the combination of water and frost accelerates the degeneration of the surface material. The open structure of porous asphalt (ZOAB) is more prone to damage than the closed structure of regular asphalt concrete. This susceptibility increases progressively with age. With porous asphalt being the road surface material of choice on Dutch motorways, Rijkswaterstaat has a keen interest in reducing frost damage, as it would prolong the life span of road surfaces, requiring less frequent resurfacing, with associated hindrance to the traffic. Rijkswaterstaat therefore invests in a core research action carried out by the Technical University Delft to discover the key factors behind the phenomenon.

In addition, Rijkswaterstaat has started technical trials on rejuvenating the aged bitumen binder in ZOAB, ZOAB+ and double layered ZOAB. Three products are being tested and monitored over several years. The first product should prevent ravelling (fragments coming loose from the road surface), the other two products should work on curing when ravelling has commenced. The trial aims to achieve an increased lifespan of porous asphalt.
