47、 not more than建筑石油沥青building petro-bitumen（GB49475）10号520195991.0230痕迹water mark拌和：在搅拌站将10#建筑沥青加热至180190摄氏度，按设计中砂与沥青配合比7：93与混合，中砂加热温度比沥青高1020摄氏度，搅拌均匀，沥青混合料出厂温度控制在170185摄氏度。Mixing: To heat the bitumen 10# up to 180190 Celsius degrees ，and bitumen is mixed with sand at the mix ratio of 7 to 93, while

48、the sand temperature shall be 1020 Celsius degrees higher than that of bitumen. The mixture temperature shall be controlled at 170185 Celsius degrees.运输：拌和的混合料，装车后应控制行车时间，及时运往工地。在运输中，不论天气如何，必须加盖保温蓬布，以保证到场混合料温度在160170摄氏度。运输时应控制装车量，并将蓬布加盖密实，且车辆选用自卸车，防止沥青漏出。运输到场后先量测温度，对低于100摄氏度的废弃不用，并查找原因，分清是运输延误时间降温，还

49、是拌和站拌和原因，如是后者，及时通知拌和站调整温度。由于沥青粘性比普通沥青大，运料车运料前车厢底部应涂刷适量的油混合料，避免粘车，并注意使油料不能混入沥青砂垫层中。沥青砂中混入油料的部分不能用到沥青砂垫层中去，废弃部分及时清理出场。Transportation: the mixture shall be delivered to the field promptly and insulate during transportation to ensure the temperature to be kept at 160170 Celsius degrees. If its lower tha

50、n 160 which is transported to the jobsite, the mixture shall be rejected and the root cause shall be investigated and necessary correction be taken.摊铺：采用人工作业铺筑的施工方法。摊铺前检查摊铺温度，温度低于100的沥青砂禁止施工，清除出现场，保证摊铺过程中均匀前进，对边角或弧形地带，采用局部加工调整处理。摊铺时在已摊铺的沥青砂垫层上铺钢板，工人用斗车经过钢板将沥青砂运至未铺设区域，摊铺工人站在未铺设区域，边摊铺边后退。在摊铺后，应及时检测摊铺厚

51、度，若不合要求，及时调整。Laying: to lay manually and the mixture temperature shall be higher than 100 to ensure the laying to be done evenly. The edges or arc area shall be trimmed properly. After laying, the layer thickness shall be checked and make any adjustment if necessary.碾压：沥青混合料的碾压，压实采用400kg压路机，在终压温度前消除

52、人为全部轨迹，达到设计要求的厚度即停止作业，以免过压。先摊铺第一层沥青砂，厚度大约40mm，并在模板上做出标记。摊铺均匀后，用400kg压路机压实，压路机无法压实的区域采用人工夯实。第一层施工完毕，经SEPCO、PMC、BSC验收后方可进行第二层施工。然后按第一层沥青砂铺设厚度与压实厚度之比摊铺第二层沥青砂，使压实后标高达到设计标高。中心点半球型将使用球形铁板压实成型。对于接茬处应将沥青砂层铲成斜面，使接茬相互搭接,上层接茬缝与下层接茬缝必须错开，防止裂缝。上下层间接茬前也应喷洒一层热沥青。最后人工平整使碾压达到7.5.2.1中质量标准的要求。施工中每隔30分钟进行一次测温，并进行详细测温记录。每车沥青砂测温点5个，中心一个，每个边角一个，共5个。修补沥青砂温度必须大于100摄氏度，施工
