瀝青混凝土路面的碾壓分三個步驟進行

瀝青混凝土路面的碾壓分三個步驟進行：第一次壓、第二次壓、終壓。碾壓縱向從低邊到高邊慢速均勻的前行。濟南瀝青砼廠家來講講，使用以下方法進行碾壓：

The compaction of asphalt concrete pavement is carried out in three steps: first compaction, second compaction, and final compaction. Roll longitudinally and move slowly and evenly from the low edge to the high edge. Jinan asphalt concrete manufacturer will explain how to use the following methods for rolling:

(1)第一次壓：使用鋼輪壓路機慢壓1遍～2遍，碾壓速度應當保持在在2.1km/h～4.1km/h。碾壓過程中應把壓路機的驅動輪面向攤鋪機，由外到內開始碾壓，在超高路段則從低到高碾壓，在坡道上應當把驅動輪由低處向高處開始碾壓。

(1) First compaction: Use a steel wheel roller to slowly compact once to twice, and the compaction speed should be maintained at 2.1km/h to 4.1km/h. During the rolling process, the driving wheel of the roller shall face the paver, and the rolling shall start from the outside to the inside. In the superelevation section, the rolling shall start from the low to the high. On the ramp, the driving wheel shall start rolling from the low to the high.

(2)第二次壓:應當緊緊跟在初壓后開始，而且不能夠隨意停頓。碾壓速度應當控制在3.1km/h～5.1km/h。使用雙鋼輪壓路機碾壓1遍，然后再振壓2遍，挨著的碾壓帶重疊后輪的一半寬度，而且不應當小于200mm。

(2) Second pressure: It should start closely after the initial pressure and should not stop at will. The rolling speed should be controlled between 3.1km/h and 5.1km/h. Use a double steel wheel roller to compact once, and then vibrate twice. The adjacent compaction strip should overlap half the width of the rear wheel and should not be less than 200mm.

(3)終壓：緊接在復壓之后就要開始，倘使經復壓后已無很突出輪跡時可不用終壓。終壓可使用雙鋼輪壓路機碾壓應當多于2遍，直到無突出輪跡為止。碾壓溫度應和碾壓速度都應控制得當。

(3) Final pressing: It should start immediately after re pressing. If there are no prominent wheel marks after re pressing, final pressing may not be necessary. The final compaction can be carried out more than 2 times using a double steel wheel roller until there are no protruding wheel marks. The rolling temperature and speed should be properly controlled.

此外接縫處理直接影響著公路工程的外觀和舒適性，所以需要做好此項工作，接縫處理主要包括橫向接縫和縱向接縫，橫向接縫首先采用3m的靠尺檢測公路的平整度，然后通過人工清除的方法處理質量問題，后涂刷瀝青，下一次進行接縫處理前，應該在已鋪層5～10mm左右的地方進行重疊，并且涂抹混合料。

In addition, joint treatment directly affects the appearance and comfort of highway engineering, so it is necessary to do a good job in this work. Joint treatment mainly includes horizontal and longitudinal joints. The horizontal joints first use a 3m guiding rule to check the flatness of the road, and then manually remove the quality problems. After that, asphalt is applied. Before the next joint treatment, overlap should be done at a place about 5-10mm away from the already laid layer, And apply the mixture.

縱向接縫一般針對由于行人和車輛的不注意造成的路面變形或污染。而對于未壓實或坍陷的部分，首先需要采用切割機進行鑿除，然后才能進行瀝青混凝土的涂刷。

Longitudinal joints are generally aimed at road surface deformation or pollution caused by carelessness of pedestrians and vehicles. For the uncompacted or collapsed parts, it is necessary to first use a cutting machine to chisel them out before applying asphalt concrete.
