9、自卸汽车运输。为满足平整度和压实度要求，项目部配备了LT320B压路机1台、LGS820压路机1台、855装载机3台，准备了1台晨光洒水车供施工和养生用水。3.5.试验室准备3.5.1.试验室组织为了对整个施工过程进行质量跟踪检测，项目部在工区建立了工地现场试验室，负责本段施工准备阶段原材料及混合料配合比试验，到施工阶段的压实度自检、试验检测，为项目实施提供试验检测数据。除此以外，试验室还配备了8名有多年经验试验员，负责材料取样、试件制作、养护等工作。3.5.2.设备配置根据级配碎石底基层施工试验检测项目的要求，工地试验室配备了完整配套的试验设备。各种仪器、设备均经过检测标定 ，能够独立完成各

10、项工程试验。3.6.辅助工程准备3.6.1.生产、生活用水生活用水采用自来水，施工用水采用自来水，水质均能满足施工和生活的需要，保证施工用水要求。3.6.2.生产、生活用电生活用电采用就近接驳地方电网，工区安装变压器，并配备发电机组作为备用电源。4.级配碎石底基层施工方案、施工工艺、施工方法及技术措施4.1.施工准备4.1.1.下承层的表面应平整、密实，具有规定的合格的高程、宽度、横坡度，没有任何松散的材料及弹簧、翻浆等不合格情况。4.1.2.检查下承层的平整度和压实度是否符合规范的规定，如不符合，则立即采取有效措施，使其符合规范规定的要求。4.1.3.路基不论路堤或路堑，须用1820T压路机

11、或等效的碾压机械进行碾压检验。在碾压过程中，如发现土过干、表层松散应适当洒水；如土过湿、发生“弹簧”现象，采取合理措施，使下承层符合规范规定的要求。4.1.4.试验室对原材料进行取样检测并进行配合比组成试验，送监理工程师审批。4.1.5.已经完成对测、试、检及电脑计量设备的检校、标定工作并报监理工程师审批。4.2.测量4.2.1.在下承层上恢复中线桩，并在两侧边缘外0.30.5米钉钢钎，标出级配碎石底基层边缘的松铺高程和设计高程。直线段每1020米设一桩，平曲线段每10米设一桩。4.2.2.进行水平测量。在两侧钢钎上用红漆定出底基层的设计标高，挂基准线。4.2.3.根据路面宽度提前将摊铺宽度用

12、白灰撒于下承层上。4.3.集料的拌和及运输拌和站根据施工配合比进行配料，拌和时对含水量、混和料级配进行严格控制，混合料出场时试验人员进行抽样检查，做到不合格的材料坚决不准出场；混合料采用自卸汽车运输，在摊铺前运输到现场，运输时料斗加盖帆布，以避免水分损失，质检人员在现场随时检查来料的级配与含水量。拌和生产过程中，含水量要略大于最佳值1%2%，以弥补混合料在运输、摊铺、碾压过程中水分损失。4.4.摊铺4.4.1.采用摊铺机施工，根据测量成果钉钎挂基准线，每10米钉一个钎，事先确定不同横坡段及渐变段，小弯道及超高部位每5米钉一个钎。在路中撒出一条灰线，内侧摊铺机的内侧电脑传感器走基准线，外侧电脑传

13、感器走基准梁，外侧摊铺机的内侧电脑传感器走已经摊铺未经碾压的结构层，外侧电脑传感器走基准线。摊铺厚度为设计厚度乘以松铺系数。4.4.2.及时消除可能出现的粗细集料离析现象，摊铺机后设专人及时进行补料。对于局部低洼处，应用齿耙将其表面5厘米以上耙松，并用新拌的混合料找补平整，在初步整形后检查混合料的松铺厚度；混合料摊铺采取半幅摊铺，两台摊铺机一前一后呈阶梯状，相隔510米，同步匀速摊铺混合料，以减少纵缝接茬。4.4.3.用摊铺机摊铺混合料时，不宜中断，如因故中断时间过长，应设置横向接缝，摊铺机应驶离混合料末端：A.人工将末端混合料弄整齐，并做成坡状，以便压路机驶出施工现场。B.混合料碾压密实。压

14、实遍数根据试验段取得的技术指标及施工工艺确定。C.在重新摊铺混合料之前，由人工切除斜坡，把已经压实的工作面切成垂直的断面。4.5.碾压成型4.5.1.经铺筑及整型的混合料应立即在全宽范围压实，按施工前确定的技术指标和施工工艺进行施工，监理工程师另有指示时除外。整形后，当混合料的含水量为最佳含水量（0.5%1.0%）时，应立即用压路机在结构层全宽内进行碾压，碾压时，轮迹重叠3050cm。压路机的碾压速度，头两遍采用1.51.7km/h，以后采用2.02.5km/h。4.5.2.碾压过程中，质检员随时检查压实度，压到规范要求的密实度为止。4.5.3.严禁压路机在已完成的或正在碾压的路段上“调头”和

15、急刹车。如必须在其上“调头”，应采取措施，以保证基层表面不受破坏。4.5.4.在混合料的含水量达到最佳时进行碾压。4.5.5.压实后应达到表面平整密实、无坑洼，施工接茬平整、无缝隙。4.5.6.碾压过程中，如有“弹簧”、松散、起皮现象，及时处理，使其达到质量要求。4.5.7.经监理验收合格后清除杂物，进行基层施工。4.6取样和试验级配碎石混合料取样试验应在施工现场每天进行一次或每2000取样一次，检查混合料的级配是否在规定的范围内；并按公路路面基层施工技术规范规定的标准方法进行压实度取检测。每200米每车道2处。（后附级配碎石底基层施工工艺流程框图）。专心-专注-专业附图：项目管理组织机构框图
