Description

Technical Field

[0001] The utility model relates to the technical field of municipal roads, in particular to a municipal road pavement cutting device. Background Art

[0002] Municipal roads refer to urban roads. Municipal roads are divided into five levels according to their position in the road network, traffic functions and service functions along the route: expressways, trunk roads, secondary trunk roads, branch roads and district roads (residential and industrial areas).
