The weight of crack router is approximately 100 lbs.; this study found the weight to be sufficient to keep the equipment stabilized while alleviating operator fatigue during its operation. In addition, the weight ensures relatively easy loading and unloading of crack router from a truck or trailer; loading and unloading of the conventional routers, which generally weigh over 500 lbs., require additional effort and may cause safety risks.
Crack router uses a cutting saw (i.e., blade) in a pneumatic manner, making it suitable for routing and widening cracks in both concrete and asphalt surfaces. Similar to CCD, an air blasting nozzle directly behind the blade attachment expels fine-grained particulate (e.g., concrete and asphalt dust) from the crack.
