目前,提高公路养护机械的科技含量,必须逐步使公路养护向机械化、环保化、多功能化和自动化迈进。机械化我国现有300多家生产筑养路机械的企业,但总体来看,目前国产养护机械品种少、规格不全、技术水平低。发达国家很早就开展了公路的施工建设,同时养护管理工作也跟上了建设的步伐。由于日常养护工作做得好,很多高速公路虽然已经使用了近半个世 At present, to improve the scientific and technological content of highway maintenance machinery, we must gradually make the road maintenance mechanization, environmental protection, multi-functionalization and automation. Mechanization of China’s existing production of more than 300 road building machinery business, but overall, the current domestic maintenance of small varieties of machinery, specifications, technical level is low. Developed countries have long carried out the road construction, maintenance and management work also keep up with the pace of construction. As a result of routine maintenance work well, many highways have been used for nearly half a century
