摘要

Worldwide, asphalt is used as material for road construction due to its excellent cost and performance. In reality however, roads can show several signs of damage such as rutting, settlements and all kinds of cracking phenomena. Reflective cracking is a type of crack caused by the reflection of a crack somewhere in a base layer through the surface, for example when concrete slabs are overlaid, during road widenings, etc. Today, different anti-cracking interface systems exist, such as SAMFs, non-woven geotextiles, geogrids (plastic, glass and carbon), combigrids and steel-reinforced nettings. The different interlayer systems all have their specific properties with advantages and disadvantages. Moreover, the performance of a specific product is not only dependent on the product properties and the root cause of the cracks but also on the correct installation of the product. Past research revealed steel to be an ideal material for an anti-reflective cracking interlayer. Steel netting as currently known is very rigid and needs to be optimally fixed by nails or a slurry seal. In addition, the relatively thick net requires an overlayer thickness of at least 5 cm to prevent the reflection of the net through the asphalt surface. In this paper we present a new, innovative, steel-based anti-reflective cracking interlayer with improved installation properties compared to traditional steel netting, enabling fast and easy installation.
