瀝青砼路面質(zhì)量受人員、材料、設(shè)備、技術(shù)工藝及水平、環(huán)境等多種因素，以及其他方面，施工單位應(yīng)嚴(yán)格按照批準(zhǔn)的施工組織設(shè)計(jì)以及規(guī)范要求進(jìn)行正確有序地施工才能保證獲得合格的瀝青砼路面。下面來(lái)講講瀝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.

瀝青砼拌制過(guò)程中瀝青混合料時(shí)而會(huì)出現(xiàn)質(zhì)量不穩(wěn)定或波動(dòng)性大，諸此任何一種瀝青混合料，在規(guī)范化、機(jī)械化的流水作業(yè)施工中，都是很難保證瀝青砼路面的質(zhì)量。例如，混合料溫度不均勻或者原各種不同規(guī)格礦料組成的變異性大或生產(chǎn)過(guò)程中沒(méi)有經(jīng)常檢驗(yàn)各種不同規(guī)格礦料的顆粒組成，將導(dǎo)致流值、孔隙率的變化，從而影響路面質(zhì)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.

因此施工時(shí)應(yīng)每天進(jìn)行抽取篩分試驗(yàn)，并將結(jié)果匯縱進(jìn)行分析，使之成為指導(dǎo)生產(chǎn)的依據(jù)，并要求及時(shí)調(diào)整冷料倉(cāng)比例；必須嚴(yán)格控制拌合樓的震動(dòng)篩篩孔尺寸。實(shí)踐證明，按下列尺寸控制的篩孔為宜。

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 # 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.

濟(jì)南瀝青砼廠家提醒，瀝青混合料的拌制應(yīng)符合下列要求：

Jinan asphalt concrete manufacturer reminds that the mixing of asphalt mixture should meet the following requirements:

（1）根據(jù)配料單進(jìn)料和拌制，嚴(yán)格控制各種礦料和瀝青用量。（2）控制各種材料和瀝青混合料的加熱溫度。（3）拌和后的瀝青混合料均勻一致，無(wú)花白、無(wú)粗細(xì)料分離和結(jié)團(tuán)成塊等現(xiàn)象。（4）每班抽樣做瀝青混合料性能、礦料級(jí)配組成和瀝青用量試驗(yàn)。（5）每班拌和結(jié)束時(shí)，清潔拌和設(shè)備，放空管道中的瀝青。作好各項(xiàng)檢查記錄，不符合規(guī)定技術(shù)要求的瀝青混合料應(yīng)禁止出廠（場(chǎng)）。

(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).
