From the road situation, the use of LB2000 Asphalt Mixing Plant made in china is the most, which is also one of the reasons for the rapid development of asphalt mixing station. Under the situation of rapid economic development, the quality problems on the surface of asphalt pavement increase gradually, which puts forward higher and higher requirements for the use quality of asphalt. It is understood that the primary factor affecting the use of asphalt quality is the ratio of raw materials, which is also involved in the introduction of asphalt mixing station, we can discuss together.
In order to obtain high-quality asphalt products, in addition to high quality LB1500 Asphalt Mixing Plant to meet the requirements, the selection of the appropriate asphalt mixture grading type is also the most important. According to the current regulations of China, the maximum particle size of asphalt mixture in the highway upper layer should not exceed half of the thickness of the layer. The maximum aggregate particle size of the middle layer asphalt mixture should not exceed two-thirds of the thickness of the layer. And the aggregate maximum nominal size of asphalt pavement structure layer mixture should not exceed one third of the thickness of the layer.
Based on this analysis, if the asphalt surface layer with a certain thickness is selected according to the above specifications, the particle size of asphalt mixture aggregate is generally larger, which is bound to bring difficulties to the construction of low price LB1000 Asphalt Mixing Plant price. Through investigation, experiment, analysis and comparison, it is known that the selection of the lower layer is wide, so the ag-201 class can be used; It is difficult to choose the mixture type of the upper layer. In order to realize the reasonable selection of the mixture ratio, on the one hand, it is necessary to investigate the aggregate resources as much as possible, and on the other hand, it is necessary to consider the model of stirring equipment.
In order to guarantee the project quality, must strict selection and inspection of engineering materials, so choose, to determine the raw materials should be used 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, make each technical indexes are in conformity with the provisions of the materials technical requirements.
