a、路面砼采用C30混凝土。

b. The trial blending of the pavement concrete is performed strictly according to the design requirement.

b、严格按照设计要求进行路面砼进行试配。

c. Before casting, the final finished surface is calculated according to the slope settling requirement of the designed pavement, the elevation of the concrete pavement is measured at arch camber in the middle of the side form, and control points are set at intervals of 3m; during the casting of the pavement which is 9,000mm in width, a longitudinal seam is formed in the middle of the pavement, and a longitudinal seam plate must be mounted strictly according to the slope settling requirement of the pavement in the designed drawing.

c、浇筑前，应根据设计路面放坡要求计算出最终完成面，然后在边模、中间起拱处测量出砼路面标高，并且每隔3m一个控制点；如浇筑9000mm宽路面时，在路中设置一道纵缝，纵缝模板安装时必须严格按照设计图纸路面放坡要求进行安装。

d. During the concrete casting of the pavement, discharging paving is performed along the casting direction, and a flat plate vibrator and a vibration rod should be tracked in place to ensure that the rod and the materials are synchronous, so that the phenomena of bubbles and slurrying occur; and the pavement is compacted initially and ground along the top of the plate by using 8# channel steel which is 5,000mm in length, a roller oraluminum alloy bars, the grinding elevation of the pavement should be 5 to 8mm higher than the preset height to ensure that the pavement concrete which is subjected to water closing and press polish meets the requirement of design elevation.

d、路面砼浇筑时，沿着浇筑顺序方向进行卸料摊铺，平板振动器及振动棒跟踪到位，保证料到棒到，以出现气泡及起浆为主；采用5000mm长8#槽钢、滚筒或是铝合金条沿着模板顶初压实、磨平，路面磨平标高应预高5~8mm，以保证路面砼闭水、压光后满足设计标高要求。

e. The press polish of the concrete pavement should be divided into three processes, namely initial grinding after casting, secondary press polish within 3 hours after casting completion and the final press polish before final setting (time is controlled by touch trial of fingers); during the secondary press polish, grinding is performed by using a polishing machine, the deformation and unevenness of abrasive discs of the polishing machine should be avoided, the grinding is performed from one end at which the concrete is cast to the other end, the intersection lengths of the abrasive discs every two times are not less than 20cm, and grinding miss positions do not occur. The polishing is performed by two operators, one person is responsible for holding the machine to ensure the stability of the polishing machine, and the other person moves a power cord.

e、砼路面压光应分三道工艺，浇筑完成后第一道初磨平；浇筑完成后3小时第二道压光；第二道压光采用，磨光机进行磨平，磨光机磨片要求无变形且无凹凸现象，磨光时由先浇筑砼一端开始磨向另一端，每两次磨片相交不少于20cm，且无漏磨处。磨光时，由二个作业员同时进行，一人撑机，保证磨光机的稳定性，一人同时移动电源线。终凝前最后一道收光（以手指触试控制时间）。

f. Galling of pavement

f、路面拉毛

The galling of the pavement is planned by using a roller or is constructed by using a special cutting machine.

路面拉毛拟采用滚筒拉毛，或者采用专用切割机进行施工。

During the galling of the roller, analuminum alloy bar or a steel pipe (which cannot slide) is positioned on the pavement in the transverse direction according to the length of the roller to avoid the influence on a galling effect due to the inclination of the roller, the galling should be performed from one side of the pavement to the other side before the final setting of the concrete and should be formed at one time, and if the roller inclines, press polish should be performed immediately, and then, the galling is performed again, wherein space between galling

lines is about 2cm.

采用滚筒施工拉毛时，根据滚筒的长度，在路面横向处安放一条铝合金条或钢管（不能滑动），以免滚筒倾斜，影响拉毛效果，拉毛应在砼终凝前从道路一侧拉向另一侧，且一次成型，如有倾斜应立即进行压光后，重新拉毛，拉毛线间距约为2cm。

Cutting should be performed by using the special cutting machine after the final setting of the concrete, lines are snapped on the pavement for mesh division according to the total width of a group of cutting discs. The width of a group of cutting lines is about 35cm, the width of the position without the cutting lines is about 65, and cutting is performed in a staggered mode according to the half width of the pavement, shown in the figure as below, the depth of the seam is about 5mm.

采用专用切割机切割时，应在砼终凝后进行，根据一组切割片的总宽度，在路面进行弹线分格。切割线一组宽度约为35cm，无切割线位置约为65cm，即按路面一半宽度错开切割，如下图所示，缝深约5mm。

Before cutting, the depths of cut of the cutting discs should be adjusted, and the cutting directions of the cutting discs should be adjusted at any time during cutting. When the cutting is stopped, a knob switch should be turned off, the cutting discs are lifted to the concrete pavement, and running is stopped.

开始切割前，应调整刀片的进刀深度，切割时应随时调整刀片切割方向。停止切割时，应先关闭旋钮开关、将刀片提至砼路面，停止运转。

During cutting, the cutting discs should be cooled by cooling water, and after cutting for partitioning is completed, slurry in the seam should be washed immediately by using pressure water.

切割时，保证刀片有冷却水对刀片进行降温处理，切割分段完成后应立即采用压力水对缝内的浆水进行冲洗干净。
