彩色沥青施工要点有哪些？
来源：/ 日期：2023-03-13
济南沥青料施工厂家表示在实际施工过程中，彩色沥青混凝土的施工工艺同普通沥青混凝土的施工工艺相差不多，但需要注意以下几个方面：
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、基层的准备和透油层的构造：在铺设下层沥青混合物之前，清洁基层，以确保基层稍微干燥和清洁，没有任何松散的石头，灰尘和杂质。喷油。铺展后，它不会流动，不会渗入基部一定深度，也不会形成油膜。彩色沥青施工厂家表示在铺装上层之前，请清洁下层的表面，以确保表面上没有灰尘，灰尘和其他碎屑，然后喷涂粘性油层。
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、参考线的确定：底层准备完毕后，进行测量和放样，标出疏松沥青材料的厚度，并指导铺路机运行方向和高度的控制参考线。已发布。
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、沥青混合料的混合与运输：彩色沥青施工厂家表示沥青的加热温度控制在170180℃（改性沥青的温度应高1020℃），矿物材料比沥青高1020℃。将沥青混合料的生产温度控制在150175℃。混合后，沥青混合料是均匀的，没有增白，粗料和细料的分离以及结块。沥青混合料由自卸车运输，在运输过程中，沥青混合料用防水油布覆盖。发现温度低于要求，颗粒具有不符合规格要求的白点，偏析，结块，水分等，混合物将被丢弃。
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、沥青混合料摊铺：使用带有自动找平装置的沥青摊铺机摊铺，并在摊铺前30分钟将整平板加热80-100°C。雨水和污水检查井的圆环用钢板覆盖，混合物手动铺设在附近并被夯实。确保摊铺温度不低于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、接缝施工：人行道分两段施工时，纵向节理采用自然节理。摊铺前，请界面处的松散混合物。在沥青路面摊铺过程中，当需要暂停施工时，下层采用斜接缝，上层采用平接缝。平缝的施工在同完成后，切割，清洁并形成缝。
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、碾压沥青混合料：在正常碾压之前，横向缝被碾压。沿接缝在垂直于车道的方向上进行，并且支撑板放置在路面的纵向边缘上，其长度足以使滚子离开滚动区域。沥青混合料摊铺成型后应立即进行压延。轧制步骤为：初始压实→再压缩→终压实。
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、成品的保护和开放：沥青混凝土人行道的终压力完成后，当人行道的温度降室外温度时，在人行道通行之前应人行道上的工具和其他杂物。
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，沥青路面容易渗透，发车辙和裂缝。维护分为两个方面：预处理和后期维护。在早期阶段，应尝试选择良好的骨料，合理的配比和合理的沥青层结构设计；后期裂缝的维护主要是喷涂乳化沥青，注浆和局部修复。更多事项就来我们网站咨询！
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.
