Raw Material Proportioning Plan for Asphalt Concrete Mixing Plant Processing
In China, most of the raw materials used in highway construction are asphalt, so asphalt concrete mixing plants have also developed rapidly. However, with the rapid development of China's economy, there are gradually more problems with asphalt pavement, so the market's requirements for asphalt quality have become increasingly high.
There are many factors that affect the quality of asphalt use. In addition to meeting conventional requirements for asphalt concrete mixing plant equipment, the proportion of raw materials is also very important. Currently, the existing industry standards in China state that the large particle size of asphalt mixture used in the upper layer of highways cannot exceed half of the thickness of that layer, and the large particle size of the aggregate in the middle of the asphalt mixture cannot exceed two-thirds of the thickness of that layer, The large size of the structural layer cannot exceed one-third of that of the same layer.
From the above regulations, it can be seen that for a certain thickness of asphalt layer, if the particle size of the selected asphalt mixture is particularly large, it also has a significant impact on the construction of asphalt concrete pavement. In order to achieve a reasonable proportion of raw materials, it is necessary to investigate the aggregate resources as much as possible. In addition, the model of asphalt concrete mixing plant is also one of the factors that need to be considered.
In order to ensure the quality of road laying, staff must conduct strict screening and inspection of raw materials. The selection and determination of raw materials should be based on the requirements of road structure and usage quality, and combined with the actual supply situation to select materials, so that all indicators of raw materials can meet the specified requirements.
