The second is to establish conservation machinery is the new concept of advanced productivity. The use of modern science and technology and new technology, new materials production of conservation machinery, is the materialized the advanced productive forces. As long as the use, maintenance, management properly, is able to play a better social and economic benefits. Such as Xiangtan Road Machinery Factory production of asphalt superconducting heating equipment, a good solution to the asphalt storage, heating, insulation, high cost, time-consuming, laborious, easy to aging asphalt, polluting the environment and a series of problems, rewrite the road maintenance with asphalt The use of soil pool, soil stove plus firewood history, it is worth promoting and use. pavement preservation maintenance surface grinder wheel speed cracks in asphalt driveway material transfer vehicle for sale
