施工機械：施工前應對拌和廠及瀝青路面施工機械和設備的配套情況、性能、計量精度等進行檢查。拌和前特別要注意瀝青拌和樓電子秤的準確度。從而保證骨料、粉料、瀝青等各種物料配比精度。
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.

試驗段試鋪
Trial paving of test section
高級公路面層在施工前應鋪筑試驗段。試驗段的長度應根據(jù)實驗目的確定，宜為100~200M。試驗段宜在直線上鋪筑。
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.
在試驗段的鋪筑過程中，應認真做好記錄分析，直接取得一手施工資料。在正式路段上施工時，要按照試驗段施工時所取得的試驗數(shù)據(jù)進行施工。
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.
施工階段包括：瀝青混凝土混合料的拌和、運輸、攤鋪、接縫處理及碾壓。
The construction stage includes: mixing, transportation, paving, joint treatment and rolling of asphalt concrete mixture.
拌和：瀝青混合料必須在瀝青拌和廠采用拌和機械拌制。可采用間歇式拌和機或連續(xù)式拌和機拌制。當工程材料從多處供料、來源或質量不穩(wěn)定時，不宜采用連續(xù)式拌和機。
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.
運輸：混合料的運輸采用較大噸位的自卸汽車運輸。從拌和機向運料車上放料時，應每卸一斗混合料挪動一下汽車位置，以減少粗細集料的離析現(xiàn)象。運輸過程中注意加蓋蓬布，用以保溫、防雨、防污染。瀝青混合料運輸車的用量應較拌和能力或攤鋪速度有所富余，保證攤鋪機連續(xù)不間斷攤鋪。注意卸料與攤鋪機之間的距離，防止碰撞攤鋪機或倒在攤鋪機外，引起攤鋪不均勻，影響路面的平整度。
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.
攤鋪：在合格的基層上按規(guī)定撒布透層、粘層、鋪筑下封層后，可進行混合料的攤鋪。首先進行施工放樣。準確的施工放樣避免基準鋼線的重度影響，其鋼支柱縱向間距不宜過大，一般5~10米并用緊線器拉緊。同時要加強監(jiān)視，防止現(xiàn)場人員擾動，造成攤鋪面的波動。攤鋪前，還要及時進行立柱、橫坡度、厚度等項指標的檢查，發(fā)現(xiàn)問題及時處理。
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.
攤鋪機攤鋪速度勻速行使不間斷，借以減少波浪和施工縫，試驗人員隨時檢測成品料的配比和瀝青含量，及時反饋拌和廠，及時調整。設專人消除粗細集料離析現(xiàn)象，如發(fā)現(xiàn)粗集料窩應予鏟除，并用新料填補。此項工作必須在碾壓之前進行，嚴禁用薄層貼補法找平，以免貼補層在使用過程中脫落壓碎，引起面層推移破裂。
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.
碾壓：保證路面達到設計的密實度和良好的平整度，是瀝青路面攤鋪碾壓階段的主要工作目標。達到此目的關鍵是要使瀝青混合料在適當?shù)臏囟认聦嵤┠雺骸Ｓ绕涫浅鯄弘A段，應盡量在規(guī)范要求的溫度范圍內的較高溫度下短時間完成。這就要求在施工組織上拌和機和攤鋪機在單位時間內的工作量必須匹配，即拌和量略大于攤鋪量,使混合料鋪筑在緩慢、均勻、連續(xù)不斷的條件下進行，并作到邊鋪邊壓。
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.
