混凝土道路施工方案_（The construction scheme of concrete road _） 1, mixture using Xuzhou model is LTU125 type automatic leveling asphalt paver (maximum paving width 12.5m), for full width paving and scraping. When the paver is automatic, the height of the spreading layer is controlled by the reference line formed by the metal side pile and the hanging steel wire. The horizontal slope is controlled by the cross slope controller, and the accuracy is in the range of + 0.1%. 2, when paving, asphalt mixture must be slow, uniform, continuous, spreading shop. Do not arbitrarily change speed or pause halfway. Paving mixture machine screw feeder in keeping the height of not less than 2 / 3 of the height of the feeder. And ensure that the paver on the full width of the section does not occur segregation. 3. The paving of the mixture is done with a domestic paver, and the reference line is used to control the elevation of the paving layer. 4, the transverse seams between the two floors should be staggered over 50cm. 5. In the place where the machinery can not be paved and repaired, artificial paving and refurbishing can be done with the consent of the supervising engineer. 6. During the construction schedule, asphalt mixture paving shall not be carried out when the temperature is below 10. (two) rolling? 1. Once the asphalt mixture is paved and leveled and irregular surface is trimmed, the material is compacted evenly and immediately. 2, the initial pressure in the mixture after paving high temperature, asphalt mixture should not be less than 120 degrees, can not produce passage, crack. The 14T double roller vibratory roller (wheel width 2.16m) is used to crush the wheel when it is rolled. The driving wheel shall be facing the paver, and the rolling route and the direction of rolling shall not be changed suddenly. The initial pressure shall be two times times. ? 3, followed by pressure to initial pressure in asphalt mixture, not less than 90 DEG C, the complex pressure type LY25 tyre ro
