沥青玛蹄脂生产厂家

沥青玛蹄脂（SMA）是一种由沥青、纤维稳定剂、砂粉及少量的细集料组成的沥青玛蹄脂填充间断级配的粗集料骨架间隙组成一体的沥青混合料。具有高含量粗集料、高含量矿粉、较大沥青用量、低含量中间粒径颗粒的组成特点。
Asphalt mastic (SMA) is a kind of asphalt mixture consisting of asphalt, fiber stabilizer, sand powder and a small amount of fine aggregate. It has the characteristics of high content of coarse aggregate, high content of mineral powder, large amount of asphalt and low content of intermediate particle size.
高含量的粗骨料在混合料中颗粒面与面直接接触、相互嵌锁构成的骨架直接承受了荷载作用，这种骨架对温度敏感性小。
The high content of coarse aggregate in the mixture of particle surface and surface contact, interlocking a skeleton directly under the load, the skeleton is less sensitive to temperature change.
含量较高的矿粉与沥青形成粘聚力很高的胶凝状物―――玛蹄脂，使得混合料的整体力学性质提高。这两方面的作用使混合料具有足够的竖向与侧向约束，在车辆荷载的作用下，不产生或只产生微小的永久性变形。
The high content of mineral powder and asphalt formed a cohesive cementitious substance, the MOFs, which made the overall mechanical properties of the mixture improved. These two functions make the mixture have enough vertical and lateral restraints. Under the action of vehicle load, no small or permanent deformation occurs.

玛蹄脂应具有恰当的耐热度（标号），根据具体使用条件和当地的极端最高温度来确定用多高的耐热度。耐热度过低，夏季易液化流淌；耐热度过高，冬季易冷脆断裂。玛蹄脂应具有一定的柔韧性，在结构发生变形时不致被拉裂。玛蹄脂还应具有足够的粘结力。
The Ma foot grease should have the proper heat resistance (label) and determine how high heat resistance is used according to the specific use conditions and the local extreme maximum temperature. The heat tolerance is too low, it is easy to liquefy in summer, the heat resistance is too high and the winter is easy to be cold and brittle fracture. The Ma foot fat should have a certain flexibility and do not be cracked when the structure is deformed. The Ma foot grease should also have sufficient bond strength.
贮存温度为-5℃—45℃,避免暴晒。自出厂之日起，贮存期为2年；运输时不得倾斜或横放，应注意使容器不要损害。
The storage temperature is -5 C - 45 C, so as to avoid insolation. Since the date of shipment, storage period for 2 years; not inclined or horizontal transportation, we should pay attention to the containers do not harm.
注意事项： 1、 搬运过程中轻搬、轻放，防止包装破裂。
Precautions: 1. Remove and put light in the handling process to prevent the packaging from breaking.
2、 存放于阴凉处，避免阳光爆晒。
2, store in the cool place, avoid the sun burst.
3、 施工现场要通风，有利于干燥。
3, the construction site should be ventilated, which is conducive to drying.
4、 施工后剩余玛蹄脂要密封保存。
4. After construction, the remaining Ma hoof fat should be sealed and preserved.
