Although a rear nozzle behind the rotary attachment produces enough air to clean loose particles from cracks, a larger volume of air is still needed to clean or chase away the dirt, debris, and/or vegetation on the pavement surface that results from the crack-routing process. Conventionally, a separate leaf blower or an air wand directly connected to an air compressor is used to clean the pavement surface after cracks are cut.
However, it is considered an additional task on a jobsite and therefore increases the costs as well as the number of operators associated with the crack-routing process. In order to eliminate this additional task, an air wand with a 3/8” inner diameter was connected to crack router machine in the same manner. After routing, the air wand can be used to clean cracks and the pavement surface. This mainly helps eliminate the process of disconnecting crack router from the air compressor to use a traditional air wand to clean the pavement.
