濟(jì)南瀝青料施工廠家表示在實際施工過程中，彩色瀝青混凝土的施工工藝同普通瀝青混凝土的施工工藝相差不多，但需要注意以下幾個方面：

Jinan asphalt construction manufacturer said that in the actual construction process, the construction process of colored asphalt concrete is not much different from that of ordinary asphalt concrete, but the following aspects need to be noted:

1、基層的準(zhǔn)備和透油層的構(gòu)造：在鋪設(shè)下層瀝青混合物之前，清潔基層，以確?；鶎由晕⒏稍锖颓鍧?，沒有任何松散的石頭，灰塵和雜質(zhì)。噴油。鋪展后，它不會流動，不會滲入基部至一定深度，也不會形成油膜。彩色瀝青施工廠家表示在鋪裝上層之前，請清潔下層的表面，以確保表面上沒有灰塵，灰塵和其他碎屑，然后噴涂粘性油層。

1. Preparation of base course and construction of prime coat: Before laying the lower asphalt mixture, clean the base course to ensure that the base course is slightly dry and clean, free from any loose stones, dust and impurities. Fuel injection. After spreading, it will not flow, penetrate into the base to a certain depth, nor form an oil film. The colored asphalt construction manufacturer said that before paving the upper layer, please clean the surface of the lower layer to ensure that there is no dust, dust and other debris on the surface, and then spray the viscous oil layer.

2、參考線的確定：底層準(zhǔn)備完畢后，進(jìn)行測量和放樣，標(biāo)出疏松瀝青材料的厚度，并指導(dǎo)鋪路機(jī)運(yùn)行方向和高度的控制參考線。已發(fā)布。

2. Determination of reference line: after the bottom layer is prepared, measure and set out, mark the thickness of loose asphalt material, and guide the control reference line of the running direction and height of the paver. Published.

3、瀝青混合料的混合與運(yùn)輸：彩色瀝青施工廠家表示瀝青的加熱溫度控制在170180℃（改性瀝青的溫度應(yīng)高1020℃），礦物材料比瀝青高1020℃。將瀝青混合料的生產(chǎn)溫度控制在150175℃?；旌虾?，瀝青混合料是均勻的，沒有增白，粗料和細(xì)料的分離以及結(jié)塊。瀝青混合料由自卸車運(yùn)輸，在運(yùn)輸過程中，瀝青混合料用防水油布覆蓋。發(fā)現(xiàn)溫度低于要求，顆粒具有不符合規(guī)格要求的白點(diǎn)，偏析，結(jié)塊，水分等，混合物將被丟棄。

3. Mixing and transportation of asphalt mixture: the color asphalt construction manufacturer said that the heating temperature of asphalt should be controlled at 170180 ℃ (the temperature of modified asphalt should be 1020 ℃ higher), and the mineral material should be 1020 ℃ higher than asphalt. The production temperature of asphalt mixture shall be controlled at 150175 ℃. After mixing, the asphalt mixture is uniform without whitening, separation and agglomeration of coarse and fine materials. The asphalt mixture is transported by dump truck. During transportation, the asphalt mixture is covered with waterproof tarpaulin. If the temperature is lower than the requirement, the particles have white spots, segregation, caking, moisture, etc. that do not meet the specification requirements, the mixture will be discarded.

4、瀝青混合料攤鋪：使用帶有自動找平裝置的瀝青攤鋪機(jī)攤鋪，并在攤鋪前30分鐘將整平板加熱至80-100°C。雨水和污水檢查井的圓環(huán)用鋼板覆蓋，混合物手動鋪設(shè)在附近并被夯實。確保攤鋪溫度不低于110130℃。

4. Asphalt mixture paving: use asphalt paver with automatic leveling device to pave, and heat the whole slab to 80-100 ° C 30 minutes before paving. The rings of rainwater and sewage inspection wells are covered with steel plates, and the mixture is manually laid nearby and compacted. Ensure that the paving temperature is not lower than 110130 ℃.

5、接縫施工：人行道分兩段施工時，縱向節(jié)理采用自然節(jié)理。攤鋪前，請清除界面處的松散混合物。在瀝青路面攤鋪過程中，當(dāng)需要暫停施工時，下層采用斜接縫，上層采用平接縫。平縫的施工在同一天完成后，切割，清潔并形成縫。

5. Joint construction: when the sidewalk is constructed in two sections, natural joints are used for longitudinal joints. Before paving, remove the loose mixture at the interface. In the process of asphalt pavement paving, when the construction needs to be suspended, the lower layer adopts inclined joints and the upper layer adopts flat joints. After the construction of flat joints is completed on the same day, cut, clean and form joints.

6、碾壓瀝青混合料：在正常碾壓之前，橫向縫被碾壓。沿接縫在垂直于車道的方向上進(jìn)行，并且支撐板放置在路面的縱向邊緣上，其長度足以使?jié)L子離開滾動區(qū)域。瀝青混合料攤鋪成型后應(yīng)立即進(jìn)行壓延。軋制步驟為：初始壓實→再壓縮→終壓實。

6. Rolling asphalt mixture: the transverse joint is rolled before normal rolling. The joint shall be carried out in the direction perpendicular to the lane, and the support plate shall be placed on the longitudinal edge of the pavement, and its length shall be sufficient to make the roller leave the rolling area. The asphalt mixture shall be rolled immediately after being paved. The rolling steps are: initial compaction → recompression → final compaction.

7、成品的保護(hù)和開放：瀝青混凝土人行道的終壓力完成后，當(dāng)人行道的溫度降至室外溫度時，在人行道通行之前應(yīng)清除人行道上的工具和其他雜物。

7. Protection and opening of finished products: after the final pressure of the asphalt concrete pavement is completed, when the temperature of the pavement falls to the outdoor temperature, the tools and other debris on the pavement shall be removed before the pavement passes.

此外要注意，瀝青路面容易滲透，發(fā)車轍和裂縫。維護(hù)分為兩個方面：預(yù)處理和后期維護(hù)。在早期階段，應(yīng)嘗試選擇良好的骨料，合理的配比和合理的瀝青層結(jié)構(gòu)設(shè)計；后期裂縫的維護(hù)主要是噴涂乳化瀝青，注漿和局部修復(fù)。更多事項就來我們網(wǎng)站http://www.tainorosa.com咨詢！

In addition, it should be noted that asphalt pavement is easy to penetrate, rut and crack. Maintenance is divided into two aspects: pretreatment and post-maintenance. In the early stage, we should try to select good aggregate, reasonable proportion and reasonable asphalt layer structure design; The maintenance of cracks in the later stage mainly includes spraying emulsified asphalt, grouting and local repair.
