Asphalt pavement must be regular and cyclical conservation, we must implement the civilized construction, safe production policy, the development of technical safety measures to strengthen safety education,popular road construction equipment strict implementation of safe operating procedures to ensure safety in production. Here are some of the initial asphalt pavement maintenance methods:

1, hot mix asphalt mixing pavement of the initial maintenance: (1) paving, compaction of the hot mix asphalt mixture pavement, to be spread the layer of natural cooling, the mixture surface temperature below 50 ? before opening the traffic. (2) vertical and horizontal construction joints is the weak link of asphalt pavement, should strengthen the initial maintenance, at any time with a three-meter ruler to find the exposed slightly uneven, shovel high fill low, after the hair, real.

2, the initial maintenance of asphalt pavement: (1) after the completion of the road, open traffic, the driving speed limit of 15Km / h below, according to the surface forming situation,asphalt crack filling equipment and gradually increased to 20Km / h. (2) Traffic or set up temporary road signs, according to the first two sides, after the middle of the control vehicle easy rutting to achieve full compaction. (3) should be at any time to disperse the traffic jam back to sweep, sweep, compaction, to form a flat and dense on the seal layer. When the road after the oil, it is necessary to timely fill with the construction of the last layer of mineral material the same embedded material, while control driving roller.

3, the asphalt surface treatment of the initial maintenance of the road: (1) layering the construction of the asphalt surface treatment of the initial maintenance of the pavement and the basic requirements of the same type of road. (2) Mixing the construction of the asphalt surface treatment of the initial maintenance of the pavement and hot mix asphalt basic requirements are basically the same. Emulsified asphalt pavement of the initial curing emulsified asphalt pavement of the initial stability is poor, the compaction of the road should be done early maintenance,asphalt crack filler price set up management, according to the actual demulsification situation, closed traffic 2-6h, in the unbreaking section, All vehicles, people through, open traffic early, should control the speed of not more than 20Km / h, and shall not brake and U-turn. When there is damage should be timely repair.
