LB1000 asphalt mixing plant raw material ratio scheme

Asphalt pavement is the most widely used road, which is one of the reasons why the asphalt mixing station develops so rapidly. However, under the situation of rapid economic development, the quality problems on the surface of asphalt pavement are also increasing, which puts forward higher and higher requirements for the use quality of asphalt. It is understood that the primary factor influencing the quality of asphalt use is the proportion of raw materials, which is also involved in the introduction of LB1000 asphalt mixing station. We can discuss it together.

In order to obtain high quality asphalt products, besides meeting the requirements of asphalt production plant, the selection of suitable asphalt mixture gradation type is also the most important. According to the regulation, the maximum size of asphalt mixture on the upper layer of the highway should not exceed half of the thickness of the asphalt mixture. The maximum size of aggregate of middle layer asphalt mixture should not exceed 2/3 of the thickness of the layer. The maximum nominal size of aggregate of asphalt pavement structure layer mixture should not exceed one third of the thickness of asphalt pavement layer.

So, if according to the standard choice, asphalt mixture aggregate size will be bigger, which will inevitably brings difficulty to the construction of asphalt concrete pavement construction. Through investigation, test, analysis and comparison, it can be seen that there is a wide choice of the lower layer, so the AG-201 type can be adopted. And top layer mixture type choice difficulty is big, in order to realize the reasonable selection of the mixture ratio, and on the one hand to examine aggregate resources as much as possible, on the other hand to consider the type of mixing equipment.

In order to guarantee the project quality, we must strictly select and inspect engineering materials, so choice of the raw materials should be according to the pavement structure and the requirement of quality, and conjunctively material supply situation, in accordance with the requirements of the relevant test procedures for inspection, and then optimize the material selection, so as to make each technical indexes are in conformity with the provisions of the materials technical requirements.
