按路面结构形式分类，有沥青混凝土路面和水泥混凝土路面;按路面维修形式分类，有路面开裂等病害的维修和路面拓寬;按路面等级形式分类,有高速公路路面维修，一级公路路面维修,二级公路路面维修,市政路面维修。
According to the classification of pavement structure, there are asphalt concrete pavement and cement concrete pavement; according to the classification of pavement maintenance, there are pavement cracks and other diseases of maintenance and pavement widening; according to the classification of pavement grade, there are highway pavement maintenance, class I highway pavement maintenance, class II Highway Pavement Maintenance, municipal pavement maintenance.
       沥青混凝土是使用最广泛的一种材料，用来保养或修复损坏的路面以及高等级沥青混凝土路面反射裂缝的预防,即使从结构上看是良好的路面，然而，一个主要的问题是，重新翻修路面后以及新建使用不久后路面常常开裂，这种开裂反映了道路原有结构中的缺陷，降低了路面的使用寿命，道路设计及施工部门已经采取了各种不同的措施来试图减轻消除反射性开裂的问题，但效果都不理想而玻璃纤维土工格栅的高抗拉强度,高弹性模量和低延伸率等特性，为消除反射裂缝提供了可靠的技术保证。
Asphalt concrete is one of the most widely used materials, which is used to maintain or repair the damaged pavement and prevent the reflection cracks of high-grade asphalt concrete pavement, Even if it is a good pavement in terms of structure, however, a major problem is that the pavement often cracks after the pavement is rebuilt and newly built for use, which reflects the defects in the original structure of the road and reduces the service life of the pavement. The road design and construction departments have taken various measures to reduce the problem of eliminating reflective cracking, but The results are not ideal and the characteristics of GFRP geogrid, such as high tensile strength, high modulus of elasticity and low elongation, provide a reliable technical guarantee for eliminating reflection cracks.
       对日沥青混凝土路面维修，可采用锚固法或自粘法，在原路面上铺设玻璃纤维土工格栅。如原路面损坏严重，可在原路面上做30~40 mm的细料沥青混合料找平层，再铺设玻璃纤维土工格栅，对旧水泥混凝土路面维修，采用自粘法、铺设玻璃纤维土工格栅。
For the maintenance of asphalt concrete pavement in Japan, the anchoring method or self-adhesive method can be used to lay glass fiber geogrid on the original pavement. If the original pavement is seriously damaged, a 30-40 mm fine asphalt mixture leveling layer can be made on the original pavement, and then a glass fiber geogrid can be laid. For the maintenance of the old cement concrete pavement, a self-adhesive method and a glass fiber geogrid can be used.
       面层中使用一层玻璃纤维土工格栅，可减少车辙现象50%，裂缝长度占面积百分比由0. 39%减少到0. 09%。延长路面使用寿命10~15年。基础层中使用一层玻璃纤维土工格栅，可节约结合料60%。
Using a layer of glass fiber geogrid in the surface layer can reduce the rutting by 50% and the percentage of crack length in the area from 0.39% to 0.09%. Extend the service life of the pavement for 10-15 years. Using a layer of glass fiber geogrid in the foundation layer can save 60% binder.
       路基层中使用一层玻璃纤维土工格栅，能提高路基.承载力17% ~43%。相同中面使用寿命使用一层玻璃纤维土工格栅，可节省沥青混合料30%。在公路工程中应用玻璃纤维土工格栅相当于投入工程造价1% ~2%的资金，可获得40%的经济效益。
Using a layer of glass fiber geogrid in the subgrade can improve the subgrade bearing capacity by 17% - 43%. Using a layer of glass fiber geogrid with the same service life of the middle surface can save 30% of the asphalt mixture. The application of GFRP geogrid in highway engineering is equivalent to 1% - 2% of the project cost, and 40% of the economic benefits can be obtained.
       铺设玻纤土工格栅时,应保证铺设平顺并使纵横向.张紧，然后用钢钉或射钉把格珊固定，固定材料一般用φ30x0.3 mm铁皮和2英寸钢钉或射钉。铺设格珊的搭接，纵向接头搭接距离不小于15cm，横向接头搭接距离不小于10 em。纵向搭接应根据沥青摊铺方向将前一幅置于后一幅上。
When laying the glass fiber geogrid, it shall be ensured that the laying is smooth and the vertical and horizontal directions are tensioned, and then the grid shall be fixed with steel nails or shooting nails. The fixing materials are generally φ 30x0.3 mm iron sheet and 2-inch steel nails or shooting nails. The lapping distance of the longitudinal joint shall not be less than 15cm, and that of the transverse joint shall not be less than 10em. The longitudinal lap joint shall place the former one on the latter one according to the asphalt paving direction.
       固定土工格珊时，不能将钉子钉于玻纤上，也不能用锤子直接敲击玻纤。固定后如发现钉子断裂或铁皮松动，则需予以重新固定。土工格珊铺设完毕后，应严格控制车辆在其上行驶，严禁车辆在其上急转向、急刹车和倾倒混合脚料，以防止对玻纤土工格栅造成损伤或破坏。
When fixing the geogrid, it is not allowed to nail the nail on the glass fiber or directly knock the glass fiber with a hammer. If the nail is broken or the iron sheet is loose after fixation, it shall be fixed again. After the geogrid is laid, the vehicle shall be strictly controlled to drive on it. It is strictly prohibited to swerve, brake and dump the mixed materials on it, so as to prevent damage or damage to the geogrid.
       注意事项：1.工人必须带手套。2.遇到需留出位置的障碍物，须用刀切段防碍，此位置的土工格珊。3.铺设时不允许起褶，因此，在铺设时必须有充足的拉力。3.土工格珊铺设并碾压后，只允许施工车辆或紧急车辆在其上行走,但应保证不因车辆的转弯或刹车对格珊造成损坏。4.已铺设玻纤土工格栅的路面,必须在当日完成面层沥青摊铺工作。将整卷格珊放在卡车后，注意其粘性面向下。确保放卷轴已锁定,布卷不致自由松动。
Precautions: 1. Workers must wear gloves. 2. when encountering obstacles that need to be set aside, it is necessary to cut a section with a knife to prevent them. 3. It is not allowed to fold when laying, so there must be sufficient tension when laying. 3. After the geogrid is laid and rolled, only construction vehicles or emergency vehicles are allowed to walk on it, but the damage to the geogrid shall not be caused by the turning or braking of vehicles. 4. For the pavement with glass fiber geogrid, the asphalt paving of the surface layer must be completed on the same day. Place the entire roll of grilles behind the truck, paying attention to the sticky side down. Make sure that the unwinder is locked and the cloth is not loose.
       相信大家看完以上内容以后，应该也对玻纤土工格栅在路面维修中的经济效益有所了解了，希望会对大家有所帮助吧。
