<P>First, the scientific arrangements for conservation plans. According to the 2016 road, bridge and tunnel inspection and evaluation results, combined with the development trend of disease, traffic and other factors, the scientific development of 2017 minor maintenance plan, do a good job of road maintenance,unpaved roads meaning daily maintenance, marking line, bridge maintenance and reinforcement, The Synchronous road maintenance, preventive maintenance and other conservation projects in the early work. 2017 plans to invest 460 million yuan to complete the 185 km of the general provincial highway safety life protection project, 160,000 square meters of road repair, 300,000 square meters mark marking line, the general provincial highway excellent road rate stabilized at 89%.</P>
<P>Second, deepen the market reform of conservation. The development of ordinary provinces trunk highway maintenance training, contract management, quality inspection, inspection and evaluation standards, the maintenance of enterprises to strictly manage and improve the quality of market maintenance and efficiency. The development of market access conditions, corporate credit evaluation standards, etc., to guide and nurture the healthy and sustainable development of the market. The development of ordinary provinces trunk road maintenance training guide,usa road asphalt alligator cracks repair clear the specific standards of conservation work.</P>
<P>Third, strengthen the bridge and tunnel maintenance management. Earnestly implement the "ten systems of safe operation of the bridge", bridge management "four one" system, strengthen the bridge dynamic operation supervision. And strive to three or four types of bridge disease in the identification within one year after the completion of maintenance reinforcement treatment, as soon as possible to eliminate the bridge security risks,how to repair cracked concrete the five types of bridges in a timely manner to take measures to shut down traffic, according to the program organization repair, to ensure the safety of the bridge. 2017 plans to 12 three or four types of bridge maintenance and reinforcement, the implementation of nine dangerous bridge renovation project, a class of more than 95% of the bridge.</P>
<P>Fourth, consolidate and improve the quality of conservation. Strengthen the dynamic supervision and maintenance of road safety, timely detection to eliminate hidden dangers, consolidate and enhance the achievements of security projects. To the new State Road 308 transformation demonstration model as a model, and actively carry out road maintenance management demonstration project, and start the G204 demonstration project construction, promote the maintenance of standardization projects. The completion of the provincial road network to adjust the milestones, signs and other replacement work, to achieve a more accurate road traffic signs set, point to a more clear.</P>
<P>Five is to improve the maintenance of production technology. Vigorously implement the mechanized operations, improve the maintenance of production efficiency,seal coating crushed recycled asphalt illinois paving shorten the maintenance time. Actively promote the recycling of waste pavement materials and life cycle cost of conservation technology to speed up the elimination of backward technology. Preliminary completion of the port road heavy traffic characteristics and durability of the pavement structure research project.</P>
