沥青混凝土拌制原理以及符合哪些要求
来源：http://www.ycgjglcl.com/ 日期：2022-07-13
沥青砼路面质量受人员、材料、设备、技术工艺及水平、环境等多种因素，以及其他方面，施工单位应严格按照批准的施工组织设计以及规范要求进行正确有序地施工才能保证获得合格的沥青砼路面。下面来讲讲沥青混凝土拌制原理以及符合哪些要求吧。
The quality of asphalt concrete pavement is affected by many factors such as personnel, materials, equipment, technical process and level, environment, and other aspects. The construction unit should carry out correct and orderly construction in strict accordance with the approved construction organization design and specification requirements in order to ensure the qualified asphalt concrete pavement. Now let's talk about the mixing principle of asphalt concrete and what requirements it meets.
沥青砼拌制过程中沥青混合料时而会出现质量不稳定或波动性大，诸此任何一种沥青混合料，在规范化、机械化的流水作业施工中，都是很难保证沥青砼路面的质量。例如，混合料温度不均匀或者原各种不同规格矿料组成的变异性大或生产过程中没有经常检验各种不同规格矿料的颗粒组成，将导致流值、孔隙率的变化，从而影响路面质量。
In the process of asphalt concrete mixing, asphalt mixture sometimes has unstable quality or large fluctuation. Therefore, any kind of asphalt mixture is difficult to ensure the quality of asphalt concrete pavement in the standardized and mechanized flow construction. For example, the uneven temperature of the mixture, the large variability of the composition of the original mineral materials with different specifications, or the particle composition of mineral materials with different specifications is not often tested in the production process, will lead to changes in flow value and porosity, thus affecting the quality of the pavement.
因此施工时应每天进行抽取筛分试验，并将结果汇纵进行分析，使之成为指导生产的依据，并要求及时调整冷料仓比例；必须严格控制拌合楼的震动筛筛孔尺寸。实践证明，按下列尺寸控制的筛孔为宜。
Therefore, during construction, sampling and screening tests should be carried out every day, and the results should be summarized and analyzed to make it a basis for guiding production, and the proportion of cold silo should be adjusted in time; The size of the vibrating screen hole of the mixing plant must be strictly controlled. Practice has proved that it is appropriate to control the mesh size according to the following dimensions.
1#筛=级配控制很大粒径+（1-2）毫米2#筛=（级配控制很大粒径-5毫米）/2+（1-2）mm3#筛=5mm+（1-2）mm4#筛=3mm依此可做适当调整，如何同三线冠新段AC25沥青砼选择筛孔为33、16、6、3的振动筛效果较好。为保持沥青砼混合料应有的质量，我们专职试验监理人员进行日常产生过程中的检验，发现问答题及时纠正处理。
1 # sieve = grading control large particle size + (1-2) mm 2 # sieve = (grading control large particle size -5 mm) /2+ (1-2) mm3 # sieve =5mm+ (1-2) MM4 # sieve =3mm, which can be adjusted appropriately. How to choose the vibrating sieve with sieve holes of 33, 16, 6 and 3 with AC25 asphalt concrete in the new section of the third line crown has a better effect. In order to maintain the proper quality of asphalt concrete mixture, our full-time test supervision personnel carry out the inspection in the daily production process, and correct and deal with the problems found in time.
济南沥青砼厂家提醒，沥青混合料的拌制应符合下列要求：
Jinan asphalt concrete manufacturer reminds that the mixing of asphalt mixture should meet the following requirements:
（1）根据配料单进料和拌制，严格控制各种矿料和沥青用量。（2）控制各种材料和沥青混合料的加热温度。（3）拌和后的沥青混合料均匀一致，无花白、无粗细料分离和结团成块等现象。（4）每班抽样做沥青混合料性能、矿料级配组成和沥青用量试验。（5）每班拌和结束时，清洁拌和设备，放空管道中的沥青。作好各项检查记录，不符合规定技术要求的沥青混合料应禁止出厂（场）。
(1) Feed and mix according to the batching list, and strictly control the consumption of various mineral materials and asphalt. (2) Control the heating temperature of various materials and asphalt mixtures. (3) The asphalt mixture after mixing is uniform, without hoarding, separation of coarse and fine materials and agglomeration. (4) The asphalt mixture performance, mineral aggregate grading composition and asphalt dosage test shall be carried out by sampling in each shift. (5) At the end of each shift, clean the mixing equipment and vent the asphalt in the pipeline. All inspection records shall be made, and asphalt mixtures that do not meet the specified technical requirements shall not be allowed to leave the factory (site).
