Crack Preparation Methods Based on Crack Size

Crack Preparation Methods Based on Crack Size
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.
 
Shanghai Doan Machinery Technology Co.,Ltd. is professional pavement crack router machine manufacturer and supplier in China. If you have any question about the crack router machine, welcome to contact with us, we will reply to you as soon as receive your inquiry.
