Anti-reflective cracking interlayers for the renovation of roads have been extensively used for the last decades. Today different anti-cracking interface systems exist: SAMI’s, non-woven geotextiles, geogrids (plastic, glass or carbon), combigrids and steel reinforcing nettings. The different interlayer systems all have their specific properties with advantages and disadvantages. Moreover the performance of a specific product is not only depending on the product properties and the origin of the cracks but also on the proper installation of the product. Past research revealed that steel is an ideal reinforcement material for an anti-reflective cracking interlayer. Steel nettings as they are known today are very rigid and require a good fixing by nails or a slurry seal. Due to their dimensions, it is also advisable to use an overlayer thickness of at least 5 cm in order to prevent the reflection of the crack/joint through the asphalt surface. In this paper we present a new steel based anti-reflective cracking interlayer with improved installation properties compared to traditional steel nettings, enabling a fast and easy installation. |
