1. Mixture proportioning technology
For the mixing ratio of asphalt raw materials and other raw materials in the process of highway construction, it is necessary to adopt appropriate usage and process means, and also meet the requirements of relative indicators. This mixing ratio technology requires professional construction personnel to carry out corresponding guidance.
2. Asphalt paving technology
In the process of highway construction, the asphalt paving process is a very important construction technology. Its laying needs to follow certain principles. In the laying process, it needs to be continuous and uniform, and it should be carried out slowly. It is necessary to ensure the orderly progress of construction work, and at the same time, it is also necessary to ensure the quality problems of construction. In the process of asphalt laying, it is necessary to ensure the continuity of construction period, and intermittent construction is not allowed. To ensure the whole construction period, it is necessary to closely contact a series of completion work. It cannot be stopped in the middle without special circumstances. After the asphalt paving is completed, the pavement shall be checked in time and the problems found shall be repaired in time. Inspection and repair of some small problems in the paving process can better prevent, control and solve them. In the process of asphalt paving, it is necessary to ensure the uniformity and continuity of the paving process in order to ensure the flatness of the pavement.
3. Pavement rolling technology
In the process of construction, the pavement shall be rolled for many times for the laying of asphalt. The overall contour of the subgrade shall be carried out through the overall rolling of the construction pavement. In the process of laying, there shall be quite high requirements for the paver. Among them, the speed requirements must be maintained at a relatively stable speed without variable speed movement. In the process of asphalt pavement rolling, there are mainly three stages of work, including initial rolling, re rolling and final rolling. The rolling work at each stage must be done well. For the initial rolling, it is the overall control of the subgrade. Re compaction is further treated and solved on the basis of initial compaction, in which one pass of rolling is enough to avoid damage to the asphalt pavement in the process of rolling. After the road surface is stable, the close connection at the mixing joint shall be carried out, and corresponding measures shall be taken to ensure that the road surface is not sinking and the road surface is flat. The final rolling is not only a crucial work, but also the most important step. After the rolling is completed, the highway construction is basically completed.
