玻纤土工格栅加筋面层的层位

       采用玻纤土工格栅加强沥青混凝土路面，可以防止和减少沥青混凝土路面各种裂缝的产生,如疲劳开裂、低温收缩开裂,由基础裂缝引发的反射裂缝。减少车辙,延长使用寿命,降低维护费用及养活维修频次，降低维护费用及养活维修频次,降低工程造价等优良功能。在沥青面层使用该材科可获得下列功能和目标:

The application of glass fiber geogrid to strengthen asphalt concrete pavement can prevent and reduce various cracks of asphalt concrete pavement, such as fatigue cracks, low temperature shrinkage cracks, reflection cracks caused by foundation cracks. Reduce rut, extend service life, reduce maintenance cost and maintenance frequency, reduce maintenance cost and maintenance frequency, reduce project cost and other excellent functions. The following functions and objectives can be achieved by using the material in the asphalt surface course:

       1.在与未增强的沥青层厚度相同的情况下，使用该材料增强的公路的疲劳寿命的处长系数是4~7。

       1. In the case of the same thickness as the unreinforced asphalt layer, the length coefficient of the fatigue life of the road strengthened by the material is 4-7.

       2.在整个沥青混凝土公路是建在相当薄弱的下层基础上时，用一层土工格栅能节约100mm 4.0 英寸)厚的高质量沥青混凝土。

       2. When the whole asphalt concrete road is built on a rather weak foundation, a layer of geogrid can save 100mm 4.0 inch thick high-quality asphalt concrete.

       3、能有效地控制、延缓及阻止由低温引起的开裂及由基础层裂缝引起的反射裂缝的作用。有效地用玻纤土工格栅增强材料增强沥青混土凝的zui小厚度是40mm。土工格栅应放在该层沥青混凝土的底部。

       3. It can effectively control, delay and prevent the crack caused by low temperature and the reflection crack caused by the crack in the foundation layer. The minimum thickness of effective reinforcement of asphalt concrete with glass fiber geogrid is 40 mm. Geogrid shall be placed at the bottom of the layer of asphalt concrete.

       4.使用玻纤土工格栅增加沥青混土凝路面可减少车辙50%以上。

       4. Using glass fiber geogrid to increase asphalt concrete pavement can reduce rutting by more than 50%.

       5.在维修系统中在原有严重开裂的沥青混土凝土路面加铺沥青混凝土层;在钢性水泥混凝土路面加铺沥青混凝土层;在半钢性基础层上面加铺沥青混凝土层。以上三种路面加.铺层采用玻纤土工格棚增强沥青混凝土。可有效阻止及延缓反射裂缝的产生，快速地吸收和扩散由重力所引起的应力。降低工程造价,延长使用寿命,降低维护费用。

       5. In the maintenance system, the asphalt concrete layer is added on the original asphalt concrete pavement with serious cracks; the asphalt concrete layer is added on the steel cement concrete pavement; the asphalt concrete layer is added on the semi-rigid foundation layer. The above three pavement layers are reinforced with asphalt concrete by glass fiber geogrid. It can effectively prevent and delay the generation of reflection cracks and quickly absorb and diffuse the stress caused by gravity. Reduce project cost, extend service life and reduce maintenance cost.

       6.40mm厚玻纤土工格栅增强沥青混凝土面层的强度相当于不同玻纤土工格栅增强的普通沥青混凝土面层100mm~ 175mm (4~7英寸)厚的强度。这是一个真正的优势。

       The strength of 6.40mm-thick fiberglass geogrid reinforced asphalt concrete surface is equivalent to the strength of 100mm-175mm (4-7in) thick ordinary asphalt concrete surface reinforced by different fiberglass geogrid. This is a real advantage.

       玻纤土工格栅加筋面层的层位。玻纤土工格栅加筋面层的层位一般加铺在面层底部，上面至少覆盖40mm厚的面层沥青混凝土。

       The layer position of reinforced surface layer of glass fiber geogrid. The layer of the surface course reinforced by fiberglass geogrid is generally laid at the bottom of the surface course, which is covered with asphalt concrete with a thickness of at least 40mm.

       对加筋路面的要求：玻纤土工格栅加筋混凝土路面。其路面应符合下列要求：

       Requirements for reinforced pavement: glass fiber geogrid reinforced concrete pavement. The pavement shall meet the following requirements:

       1.纵向平整度横向路拱的坡度与平硕性均应符合设计标准，若达不到标准,应在加铺之前作有关处理。

       1. The gradient and flatness of longitudinal flatness and transverse crown shall meet the design standard. If they fail to meet the standard, relevant treatment shall be conducted before the additional paving.

       2.加铺前对路面承载能力进行评定,若承载能力不足,达不到设计标准.或水混混凝土路面有板底脱空现象.均应作增强处理。水泥混凝土路面的接缝与裂缝应事先清理、填充。

       2. Evaluate the bearing capacity of the pavement before the overlay. If the bearing capacity is insufficient, it can not meet the design standard, or the slab bottom of the water concrete pavement is hollowed out, it should be strengthened. The joints and cracks of cement concrete pavement shall be cleaned and filled in advance.

       3.原有路面及基层表面有局部松散、坑洞及扩散型裂缝,应事先修补、填塞,以保持表面状况完好。

       3. The original pavement and base course surface are partially loose, potholes and diffusion cracks, which shall be repaired and filled in advance to keep the surface in good condition.

       4.原有路面表面应冲洗干净,清除尘土、松散颗料及杂物。

       4. The original pavement surface shall be washed clean to remove dust, loose particles and sundries.

       相信大家看完以上内容以后，应该也对玻纤土工格栅加强沥青混凝土路面有所了解了吧，希望会对大家有所帮助吧。
