Bitumens for joint and crack filling

Bitumens for filling joints and cracks in pavements of roads, airports, parking places and other trafficked areas are specially modified bitumens, so as to resist thermal tensile and compressive stresses developed as a result of temperature changes. At the same time, they possess excellent resistance to permanent deformation. Depending on the additives incorporated in the bitumen, these modified bitumens can also be fuel resistant. 

Bitumens for filling joints are hot-applied (160°C-180°C) or cold-applied at ambient temperatures. 

More information on the specified properties of hot-applied and cold-applied bitumens for filling joints and cracks according to European standards is given in CEN EN 14188-1 (2004) and CEN EN 14188-2 (2004), respectively. 

The corresponding American standards on bitumens for filling joints and cracks are ASTM D 3406 (2006), ASTM D 5329-07 (2009), ASTM D 5893-04 (2010) and ASTM D 7116 (2005). 

To ensure construction quality and since there is a great variety of polymer-modified bitumens in the market, the properties of the polymer-modified bitumen must be specified precisely to satisfy the needs.
