The traditional procedures for preparing roadway cracks for sealing/filling are largely ineffective, labor intensive, and/or dusty. Further, working crews can be often exposed to safety hazards. Although routing is the best approach among the methods listed below for cleaning cracks, it is not a solution for complete crack preparation. Routing only excavates narrow cracks on both sides of the crack surface.
All routing equipment shall consist of mechanical routers capable of continually creating well-defined right angled routs and keeping the rout centreline within 8 mm of the centre of the crack and providing a rout width of 40 to 50 mm and a depth of not less than 8 mm.
