6、.5mm,9.5-19mm，,19-31.5mm四种规格的碎石。所需原材料的石料强度经过检查全部合格，加工出来的各级材料都必须经过试验检测合格，有机质不能大于2%,才能投入使用。此外在运输和储存过程中应加强管理，使材料不会变质、不被污染。1、材料规格：0-4.75mm,4.75-9.5mm,9.5-19mm,19-31.5mm三种，经轧制碎石的材料可以是各种类型的岩石(软质岩石除外)、圆石或矿渣。2、碎石中针片状颗粒的总含量应不超过20。碎石中不应有粘土块、植物等有害物质。3、细集料采用专门轧制的细碎石集料。也可以用天然砂砾或粗砂代替石屑。天然砂砾的颗粒尺寸应该合适，必要时应筛除其中的超尺寸颗

7、粒。天然砂砾或粗砂应有较好的级配。水泥稳定碎石颗粒级配范围要求见下表：粒径（mm）通过下列筛孔（mm）的质量百分率（%）31.526.5199.54.752.360.60.075通过百分率（%）10090-10072-8947-6729-4917-358-220-7七、水泥稳定碎石配合比设计1、目标配合比 根据图纸设计及试验、施工规范要求，经试验确定目标配合比。2、 生产配合比a、按生产配合比进行试拌，铺筑试验段，由此确定生产用的标准配合比。标准配合比一经确认，不得随意改动，如材料确实发生变化时，需立即上报监理、业主重新认证标准配合比。b、水泥稳定碎石已进行检测，物理指标如下(1)颗粒组成应是

8、一根顺滑的曲线。（2) 3.5%水泥稳定碎石最大干密度为2.32 g/cm3，最佳含水率为 6.0% ；5%水泥稳定碎石最大干密度为2.34g/cm3，最佳含水率为5.8%，集料压碎值26。 （3）5%水泥稳定碎石上基层7天无侧限抗压强度3.2mpa，3.5%水泥稳定碎石7天无侧限抗压强度2.8mpa，水稳中水泥含量不应超过5%。八、施工准备对k10+525k10+725段路面底基层严格按照相关技术规范要求进行验收，各项检测指标符合设计要求，经业主及监理批准同意经行基层试验段铺筑。对施工工人、机械操作手进行全方位培训，以确保施工时有序地保质保量的进行安全文明施工。对施工作业段派出专人提前采取安

9、全措施、实施有效的交通安全管制。对各种施工机具进行全面检修，应经调试并使其处于良好的性能状态。应配备有足够的机械，施工能力需配套，重要机械宜有备用设备。工艺流程如下：底基层验收与清理水泥级配碎石水施工放样拌合机和混合料摊 铺 机 就 位混合料质量检验稳拌站运输水泥稳定级配碎石摊铺检 查 与 修 整碾 压压实度高程平整度检测 养 生 九、施工放样施工前对铺筑路段按10m一个断面进行路线标高及中边桩测量。各结构层的纵断面高程（厚度）采用悬挂基线来控制。每间隔20米设一基准线立柱，弯道处根据现场情况增加立柱，高程通过悬挂钢丝控制。为保证钢丝绷紧，在两端紧线器上安装紧绳器，以防止钢丝下垂影响高程控制。

10、钢丝基准线悬挂完成后，对基准线进行复测。为保证工程质量，摊铺机操作始终沿灰线行走，根据钢丝控制高程。十、中心站集中加工、运输、摊铺、碾压、接茬施工1、水泥稳定碎石料在指定石料厂加工，经检测合格运至稳拌站。2、不同粒级的碎石和石屑等细集料需隔离，分级分仓堆放。3、水泥稳定碎石搅拌由中心站通过电脑计量按设计配比拌制，拌制后级配碎石抽检其级配，满足要求后运至现场。4、本合同段水泥稳定碎石基层采用摊铺机摊铺混合料。5、基层施工前先进行底基层的验收工作。验收包括量测宽度、厚度、高程、横坡、压实度等各项实测结果，实测结果达到质量标准的规定值和允许偏差符合技术规范要求后进行基层施工，路面底基层应坚实、平整无

11、坑洼、松散、现象。不合格及时修理。在施工该基层前对底基层进行清扫和洒水使表面潮湿，下基层施工完毕，重复上述工序进行剩余两层上基层施工。6、材料的运输采用15t以上的自卸式汽车进行运输，运输到现场后由专人指挥，保证材料运输到规定的位置；材料的摊铺采用摊铺机进行摊铺，局部地方采用人工辅助添料；摊铺过后采用20t以上的振动式压路机进行压实，碾压按照先轻后重的原则，用振动压路机紧跟混合料的摊铺面进行碾压。开始用振动压路机不挂振进行碾压12遍，然后挂振碾压。直线段由两侧路边向路中心或自横坡度低的一侧向高的一侧碾压，碾压范围应比边缘宽出10cm，碾压时重叠1/2轮宽，碾压速度1.51.7km/h。复压时用

12、振动压路机继续碾压。碾压速度2.02.5km/h。碾压顺序同前，碾压至要求的压实度为止。碾压过程中如气温高或风天基层表面易风干，人工进行喷水，继续碾压。在操作中应做到三快即快运输、快摊铺、快碾压。确保从稳拌站出料到碾压完毕时间不超过2小时。在施工过程中应控制结构层高程，宽度，厚度，平整度，横坡等。7、接茬：（1）水泥稳定碎石施工是按基层全宽度半幅摊铺。（2）操作人员将末端混合料横向切齐，紧靠混合料放两根方木，方木的高度与混合料的压实厚度相同，然后将末端混合料压平且符合设计高程。（3）将混合料按高程碾压密实，然后将方木和砂砾材料除去，并将底基层清扫干净。（4）如摊铺中断后因故未能按上述方法处理横

13、向接缝，且中断时间已超过2小时，将未压实的混合料铲除，并且在铲除过程中用3m直尺检测平整度，将已碾压密实且高程、平整度符合要求的末端挖成一横向与路中心线垂直的向下的断面。同时及时清理干净底基层表面混合料。（5）水泥稳定碎石基层碾压成型，压实度合格后，在基层顶面覆盖土工布，立即开始用洒水车洒水养生。洒水次数视气候而定，在养生期间始终保持基层表面潮湿。十一、质量控制标准（一）一般规定1 、必须建立、健全工地试验，质量检查及工序间的交接验收等制度。试验、检验应做到原始记录齐全，数据真实可靠。2、 工地试验室应能进行所用基层材料的各项试验，还应具备进行现场压实度和平整度检查的能力，应配备弯沉测量的仪器

14、。3 、各个工序完结后均应进行检查验收。经检验合格后方可进行下一道工序。凡经检验不合格的段落，必须进行补救，使其达到要求。具体项目见下表：水泥稳定碎石基层实测项目项次检查项目规定值或允许偏差高速公路一级公路检查方法和频率1压实度(%)98按附录b检查。每200m每车道2处2纵断高程（mm）+5，-10水准仪：每200m测4个断面3宽度（mm）符合设计要求米尺：每200m测4处4平整度（mm）83m直尺：每200m测2处*10尺5横破（%）0.3水准仪：每200m测4个断面6厚度（mm）代表值-8按附录h检查，每200m每车道1点合格值-157强度符合设计要求按附录g检查(二)材料的标准试验1、

15、 在组织现场施工以前以及在施工过程中，原材料或者混合料发生变化时，必须对拟采用的材料进行规定的基本性质试验，评定材料质量和性能是否符合要求。2 、对用做基层的原材料，应进行公路路面基层施工技术规范jtj034-2006表9.2.2所列的试验。十二、试验数据的整理和结果（一）压实度及含水量 序号桩号碾压第五遍压实度/含水量碾压第六遍压实度/含水量碾压第七遍压实度/含水量碾压第八遍压实度/含水量1k10+525左幅91.4/5.591.8/5.291.8/5.793.1/5.993.1/5.493.5/5.795.3/5.795.7/5.895.3/5.297.4/5.587.8/5.597.8/

23、系数为1.3，以此控制现场施工。（4）填料的含水量控制在最佳含水量的2%之间。（5）碾压方法：先轻后重，由两侧路边向路中心或自横坡度低的一侧向高的一侧碾压，碾压范围应比边缘宽出10cm，碾压时重叠1/2轮宽，碾压速度1.51.7km/h。english is the most widely spoken language in the history of our planet, used in some way by at least one out of every seven human beings around the globe. half of the worlds books
