第一卷 水泥砼路面机械摊铺
    1特点
    1．1本工法采用螺旋布料器布料、多根振动棒振动密实、振捣器上下振捣压入粗骨料、成型模板挤压成型和抹光等工序，确保了水泥混凝土路面密度，特别是路面的平整度有了明显的提高，能满足高等级道路、机场飞行区等工程的高标准质量要求。
    1．2摊铺施工过程全部自动化，采用电动液压控制系统、传感器控制转向和升降，它集水泥混凝土的布料、摊铺、密实、成型和抹光等功能，使水泥混凝土路面一次成型。并且还能适应不同宽度（3．66～9．75m）和不同厚度（最大厚度可达48．3cm）的水泥混凝土路面施工要求，摊铺速度根据混凝土的供料速度而定。
    1．3在摊铺过程中，辅以人工配合，能按设计要求在水泥混凝土路面中间或两侧边自动打入钢筋传力杆。
    2适用范围
    适用于水泥混凝土类的高等级公路、城市道路、机场飞行区、集装箱堆场和广场地坪等工程。
    3工艺原理
    水泥混凝土路面滑模式摊铺机工艺原理如下图所示：
 
通过螺旋布料器（包括二次布料器）均匀布料，振动棒和振捣器的振实，经滑模板滑出成型，最后由抹光板搓柔整修表面。
    4施工工艺
在验收合格的基层或对基层进行整修合格后，进行摊铺基准
Volume of cement concrete pavement paving
    1 Features
    1.1 The Public Law spiral cloth fabric devices, and more dense root vibration vibrator, vibrators vibrating pressure down into the coarse aggregate, forming the template and the trowel and other extrusion processes, to ensure that the cement concrete pavement density, especially the smoothness of the road has increased significantly, to meet the high-grade roads, airport flight zone and other projects of high standards of quality requirements.
    1.2 Paving the process fully automated, using electro-hydraulic control systems, sensors, steering and lift control, it set the fabric of cement concrete, paving, compacting, forming and trowel etc, to make a molding of cement concrete pavement. And can adapt to different widths (3.66 ~ 9.75m) and different thickness (maximum thickness of up to 48.3cm) of cement concrete pavement construction requirements for concrete paver speed based material speed.
    1.3 in the paving process, supplemented with artificial, can according to design requirements in the cement concrete pavement into the middle or side edge of reinforced dowel bar automatically.
    2 Scope
    Applicable to the cement concrete highway class, urban roads, airport flight zone, container yard and plaza floor works.
    3 Process principle
    Cement concrete pavement slippery principle of spreading machines process as shown below:
 
Device through the spiral fabrics (including secondary fabric devices) Uniform fabrics, vibrator and vibrators tap, slide out by sliding the template shape, and finally by the trowel plate rubbing the surface of soft refurbishment.
    Construction Technology 4
In the acceptance of primary or basic refurbishment after passing paving benchmark
