Mixing Ratio Plan of Raw Materials Processed by Asphalt Concrete Mixing Plant
In China, asphalt is mostly used as raw material for highway construction, so the asphalt concrete mixing plant has developed rapidly. However, with the rapid development of China’s economy, the problems of asphalt pavement have gradually increased, and the market’s requirements for asphalt quality have become higher and higher.
There are many factors affecting the quality of asphalt use. In addition to the requirement that the asphalt concrete mixing plant equipment needs to meet the conventional requirements, the mixing ratio of raw materials is also very important. At present, China’s existing industry standards stipulate that the large particle size of asphalt mixture used for the upper layer of highway pavement cannot exceed half of the thick layer, and the large particle size of asphalt mixture for the middle layer cannot exceed two-thirds of the layer thickness. The large size of the structural layer cannot exceed one-third of the same layer.
From the above regulations, it can be seen that if the asphalt layer has a certain thickness and the particle size of the asphalt mixture used is particularly large, it will have a very big impact on the construction of asphalt concrete pavement. If you want to have a reasonable ratio of raw materials, you must investigate the aggregate resources as much as possible. In addition, the type of asphalt concrete mixing plant is also one of the factors that need to be considered.
In order to ensure the quality of road pavement construction, personnel must strictly screen and inspect raw materials. When selecting raw materials, it is necessary to consider the requirements of pavement structure and use quality, combined with the actual supply situation, so as to select materials that meet the required specifications.
