Technical Field
[0001] The utility model relates to the technical field of roadbed construction, in particular to a paving device for roadbed construction. Background Art
[0002] The roadbed is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide necessary conditions for track or road paving and train or vehicle operation, and to bear the static and dynamic loads of tracks and locomotives or road surfaces and traffic loads, while transferring and diffusing the loads deep into the foundation. Roadbed engineering construction refers to construction through machinery including earth-moving machinery, excavation and loading machinery, engineering transport vehicles and compaction machinery.
