标准沥青路面施工需要注意哪些流程？
来源：/ 日期：2022-03-21
施工机械：施工前应对拌和厂及沥青路面施工机械和设备的配套情况、性能、计量精度等进行检查。拌和前特别要注意沥青拌和楼电子秤的准确度。从而保证骨料、粉料、沥青等各种物料配比精度。
Construction machinery: before construction, the matching condition, performance and measurement accuracy of mixing plant and asphalt pavement construction machinery and equipment shall be checked. Before mixing, pay special attention to the accuracy of the electronic scale in the asphalt mixing plant. So as to ensure the proportioning accuracy of aggregate, powder, asphalt and other materials.

试验段试铺
Trial paving of test section
公路面层在施工前应铺筑试验段。试验段的长度应根据实验目的确定，宜为100~200M。试验段宜在直线上铺筑。
The test section shall be paved before the construction of the surface course of high-grade highway. The length of the test section shall be determined according to the purpose of the experiment, preferably 100 ~ 200m. The test section should be paved on a straight line.
在试验段的铺筑过程中，应认真做好记录分析，直接取得一手施工资料。在正式路段上施工时，要按照试验段施工时所取得的试验数据进行施工。
During the paving process of the test section, careful records and analysis shall be made to directly obtain first-hand construction data. When constructing on the formal road section, the construction shall be carried out according to the test data obtained during the construction of the test section.
施工阶段包括：沥青混凝土混合料的拌和、运输、摊铺、接缝处理及碾压。
The construction stage includes: mixing, transportation, paving, joint treatment and rolling of asphalt concrete mixture.
拌和：沥青混合料必须在沥青拌和厂采用拌和机械拌制。可采用间歇式拌和机或连续式拌和机拌制。当工程材料从多处供料、来源或质量不稳定时，不宜采用连续式拌和机。
Mixing: the asphalt mixture must be mixed by mixing machinery in the asphalt mixing plant. Batch mixer or continuous mixer can be used for mixing. When the engineering materials are supplied from multiple sources or the quality is unstable, the continuous mixer should not be used.
运输：混合料的运输采用较大吨位的自卸汽车运输。从拌和机向运料车上放料时，应每卸一斗混合料挪动一下汽车位置，以减少粗细集料的离析现象。运输过程中注意加盖蓬布，用以保温、防雨、防污染。沥青混合料运输车的用量应较拌和能力或摊铺速度有所富余，保证摊铺机连续不间断摊铺。注意卸料与摊铺机之间的距离，防止碰撞摊铺机或倒在摊铺机外，引起摊铺不均匀，影响路面的平整度。
Transportation: the mixture is transported by dump truck with large tonnage. When discharging materials from the mixer to the truck, move the truck position for each bucket of mixture to reduce the segregation of coarse and fine aggregates. During transportation, the tarpaulin shall be covered for thermal insulation, rainproof and pollution prevention. The amount of asphalt mixture transport vehicle shall be more than the mixing capacity or paving speed to ensure the continuous paving of the paver. Pay attention to the distance between the unloading and the paver to prevent collision with the paver or falling outside the paver, resulting in uneven paving and affecting the flatness of the road.
摊铺：在合格的基层上按规定撒布透层、粘层、铺筑下封层后，可进行混合料的摊铺。进行施工放样。准确的施工放样避免基准钢线的重度影响，其钢支柱纵向间距不宜过大，一般5~10米并用紧线器拉紧。同时要加强监视，防止现场人员扰动，造成摊铺面的波动。摊铺前，还要及时进行立柱、横坡度、厚度等项指标的检查，发现问题及时处理。
Paving: the mixture can be paved after the prime coat, tack coat and lower seal coat are spread on the qualified base course according to the regulations. First, carry out construction setting out. The accurate construction setting out shall avoid the severe influence of the reference steel line, and the longitudinal spacing of the steel pillars shall not be too large, generally 5 ~ 10m, and shall be tightened with a wire tightener. At the same time, the monitoring shall be strengthened to prevent the disturbance of on-site personnel from causing the fluctuation of paving surface. Before paving, the column, cross slope, thickness and other indicators shall be checked in time, and the problems found shall be handled in time.
摊铺机摊铺速度匀速行使不间断，借以减少波浪和施工缝，试验人员随时检测成品料的配比和沥青含量，及时反馈拌和厂，及时调整。设专人粗细集料离析现象，如发现粗集料窝应予铲除，并用新料填补。此项工作必须在碾压之前进行，严禁用薄层贴补法找平，以免贴补层在使用过程中脱落压碎，引起面层推移破裂。
The paving speed of the paver is uniform and uninterrupted, so as to reduce waves and construction joints. The tester shall detect the proportion and asphalt content of the finished material at any time, feed back to the mixing plant in time and adjust it in time. Special personnel shall be assigned to eliminate the segregation of coarse and fine aggregates. If coarse aggregate pits are found, they shall be removed and filled with new materials. This work must be carried out before rolling, and it is strictly prohibited to level with the thin-layer patching method, so as to prevent the patching layer from falling off and crushing during use, resulting in the displacement and fracture of the surface layer.
碾压：保证路面达到设计的密实度和良好的平整度，是沥青路面摊铺碾压阶段的主要工作目标。达到此目的关键是要使沥青混合料在适当的温度下实施碾压。尤其是初压阶段，应尽量在规范要求的温度范围内的较高温度下短时间完成。这就要求在施工组织上拌和机和摊铺机在单位时间内的工作量必须匹配，即拌和量略大于摊铺量,使混合料铺筑在缓慢、均匀、连续不断的条件下进行，并作到边铺边压。
Rolling: ensuring that the pavement reaches the designed compactness and good flatness is the main work goal of asphalt pavement paving and rolling stage. To achieve this goal, the key is to make the asphalt mixture roll at an appropriate temperature. In particular, the initial pressing stage shall be completed in a short time at a higher temperature within the temperature range required by the specification as far as possible. This requires that in the construction organization, the workload of mixer and paver in unit time must be matched, that is, the mixing volume is slightly greater than the paving volume, so that the mixture paving can be carried out under the condition of slow, uniform and continuous, and the mixture can be paved and pressed at the same time.
