Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, and more specifically, to a highway construction and maintenance device. Background Technology

[0002] Highway construction and maintenance refers to a series of engineering and technical activities for the construction, maintenance and repair of highways. It includes the construction of new highways, the maintenance of existing highways, and the repair and upgrading of highway facilities. The purpose of highway construction and maintenance is to ensure the safety, comfort and traffic capacity of highways, extend the service life of highways, and improve the efficiency of transportation.
