裂缝是路面常见病害之一，裂缝形成后若不及时处理，雨水将通过裂缝进入面层和基层，在行车荷载的作用下形成动水对结构层造成冲刷，产生唧浆或基层松散等水损害，终导致路面产生龟裂、坑槽等病害。
Cracks are one of the common diseases on road surfaces. If not treated in a timely manner after the formation of cracks, rainwater will enter the surface layer and base layer through the cracks. Under the action of driving loads, dynamic water will form and cause erosion on the structural layer, resulting in water damage such as slurry pumping or loose base layer, ultimately leading to cracks, potholes, and other diseases on the road surface.
灌缝是处理裂缝的常用方法之一。灌缝是一种有效的预防性养护措施，灌缝的目的就是防水。
Grouting is one of the commonly used methods for treating cracks. Grouting is an effective preventive maintenance measure, with the purpose of waterproofing.
灌缝可延长沥青路面的使用寿命，且施工费用较低，仅为挖补路面费用的1/6。因此路面灌缝机得到了广泛应用。
Filling joints can extend the service life of asphalt pavement, and the construction cost is relatively low, only 1/6 of the cost of repairing the pavement. Therefore, road joint filling machines have been widely used.
春季是灌缝施工的黄金季节，它减少了热涨冷缩对路面裂缝的影响。同时温度变化小，气候温和对灌缝料的高温稳定性影响较小。
Spring is the golden season for joint grouting construction, which reduces the impact of thermal expansion and contraction on road cracks. At the same time, the temperature change is small, and the mild climate has little impact on the high-temperature stability of the grouting material.
灌缝所需要的材料也有特殊要求。灌缝胶要与缝壁粘结能力强，高温时不粘轮，低温时不脆裂，耐久性好。
There are also special requirements for the materials required for joint filling. The joint sealant should have strong adhesion to the joint wall, not stick to the wheel at high temperatures, and not brittle at low temperatures, with good durability.
灌缝的工艺流程如下：
The process flow of joint filling is as follows:
灌缝工艺流程
Grouting process flow
开槽按照裂缝标示，调整好开槽机的开槽宽度和深度，对准裂缝的中线切割出均匀的U型凹槽n，开槽深宽比不应超过2:1，开槽少1厘米宽，1.2厘米深。
According to the crack marking, adjust the slot width and depth of the slot machine, align it with the centerline of the crack, and cut a uniform U-shaped groove n. The depth to width ratio of the slot should not exceed 2:1, and the slot should be at least 1 cm wide and 1.2 cm deep.

清理裂缝时为保证灌缝胶与缝壁间粘结牢固，多采用压缩空气法和钢丝刷法清理裂缝。
When cleaning cracks, compressed air method and wire brush method are often used to ensure the firm adhesion between the sealant and the joint wall.
在灌缝时，为了防止车轮粘起灌缝胶，有时在灌入灌缝胶后还要在其上撒上砂子。
When filling the joint, in order to prevent the wheel from sticking the joint sealant, sometimes sand is also sprinkled on it after pouring the joint sealant.
对裂缝灌填完成后，根据气温情况，冷却10-20min后开放交通。
After filling the cracks, cool down for 10-20 minutes according to the temperature and open up traffic.
灌缝注意事项：
Cautions for joint filling:
一、施工温度：施工温度是造成密封胶脱落的原因之一。路面潮湿和温度低于4℃就会降低密封胶的粘结力，容易脱落。
1、 Construction temperature: Construction temperature is one of the reasons for sealant detachment. Wet road surfaces and temperatures below 4 ℃ can reduce the adhesive strength of the sealant, making it easy to peel off.
路面整体温度较低，密封胶灌缝后，温度下降较快，密封胶收缩明显，密封胶与槽壁之间温度应力较大，将降低密封胶与路面的粘结力。
The overall temperature of the road surface is relatively low. After the sealant is poured into the joint, the temperature drops quickly, and the sealant shrinks significantly. The temperature stress between the sealant and the groove wall is relatively high, which will reduce the bonding force between the sealant and the road surface.
二、裂缝湿度：灌缝时路面应干燥，如潮湿会降低密封胶与路面的粘结力，造成部分密封胶脱落。
2、 Crack humidity: When filling cracks, the road surface should be dry. If it is damp, it will reduce the bonding force between the sealant and the road surface, causing some of the sealant to fall off.
三、保持清洁：灌缝前，用空压机将开过槽后的裂缝中的灰尘杂物及周边松动的物体干净，保持裂缝的清洁。
3、 Maintain cleanliness: Before filling the crack, use an air compressor to clean the dust, debris, and loose objects around the crack after the slot has been opened, and maintain the cleanliness of the crack.
四、灌缝范围：车辙严重，尤其是形成网裂的路面，不宜用此方法处理裂缝。
4、 Crack filling range: Severe rutting, especially on road surfaces that form mesh cracks, should not be treated with this method.
