1. Low cost
The road local cold recycling machine uses all the old road formwork raw materials, which reduces the foundation pit excavation, transportation, waste and purchase of new materials of the old formwork raw materials during road maintenance or renewal, resulting in a significant reduction in the cost. Compared with the traditional method, the local cold regeneration of the road can control the cost with the difference of the thickness of the regeneration layer. The thicker the thickness of the cold regeneration pavement is, the more the control cost is. For example, in the construction of the reconstruction project of Panshi section of Jilin Provincial Railway in 2005, after the technical mutual exclusion plan of economic development is relatively, the cold recycling construction and processing technology of concrete is selected to carry out the recycling of rural road base, saving nearly 43% of the project investment. The thickness of the recycled layer is 27cm, and the engineering budget of the recycled layer is 42 yuan / m2. However, the traditional handicraft is selected, which needs double-layer water stability reinforcement. In addition, the external transfer of raw materials of the original pavement needs to be eliminated, and the engineering cost is 73 yuan / M2. In the following example, it can be seen that the cold recycling technology can greatly reduce the engineering cost. In the rural base course of pavement, the reuse of its raw materials can save a lot of project investment. In the low-level pavement, the use of cold regeneration processing technology can improve the level of rural base course of pavement and reduce the capital investment of the overall surface course. The existence of such objectivity and specific advantages is the original power to promote the recognition of in-situ cold regeneration technology and obtain the rapid development trend.
2. High efficiency
The construction of road local cold recycling machinery and equipment can carry out asphalt road, crushing, addition, mixing and paving at one time, which simplifies the construction procedure and reduces the construction period. The local cold regeneration mechanical equipment shall be applied, and the daily construction can carry out the labor volume of square meters.
3. Little harm from temperature standard
The cold regeneration of old land can be constructed under the standard of uncertain temperature and natural environment. Except for the general changeable temperature and drizzle temperature when the precipitation is large, the cold regeneration machine can be constructed immediately even after the rainstorm.
4. The harm to urban public transport is significantly reduced
The characteristics of cold regeneration rental construction are that the cold regeneration process is simple and clear, there are few construction equipment, and it is not sensitive to the impact on traffic travel. All cold regeneration machinery and equipment can be located in the same traffic lane without endangering the driving of motor vehicles in another traffic lane. Open construction can be carried out, which is very suitable for road construction under the condition of large traffic flow or narrow road width. When half of the road is constructed, the other half is still used, which greatly improves the traffic conditions under construction. Therefore, as a road maintenance method and new technology with high efficiency, environmental protection and energy conservation, environmental protection, pavement cold recycling machine has long become one of the key ways of road renewal and reconstruction in the world.
