The types of crack router that are available to cut asphalt cement pavement include rotary-impact routers and saws. An important factor that is involved in selecting the best equipment to create the reservoir include: productivity, meaning how many linear feet can be routed in a period of time, operating costs for the machinery, including the number of people needed to carry out the routing or sawing functions, maneuverability in order to follow the meandering crack and choosing the mechanism that has a limited potential to create damage to the pavement.
The rotary-impact router is said to be the most recommended and commonly used machine to rout reservoirs because it has the highest production-rate, the lowest cost of operation, good maneuverability and has less potential to damage the pavement especially when using carbide-tipped router bits.
