沥青高粘剂的优势
1、沥青高粘剂对抗剪强度有较大的影响:粘层抗剪强度会随着粘层厚度的增加先升后降,并在中间出现峰值,不同粘结层材料出现抗剪强度峰值的位置也不相同;
1, asphalt, high adhesive against shear strength has great influence: adhesive layer shear strength will increase with the thickness of adhesive layer at first and lowered later appear in the middle peak, different bonding layer material in the position of the peak shear strength is not the same;
2、温度对沥青高粘剂的抗剪强度和抗拉强度有较大的影响,在高温条件下,高粘沥青的抗剪和抗拉性能明显好于其他两种粘层材料;
2. The temperature has a great influence on the shear strength and tensile strength of asphalt viscosifier. Under high temperature conditions, the anti-shear and tensile properties of high viscous asphalt are better than those of the other two clay materials.
3、低温肯塔堡飞散损失率相差1/2左右,具有优异的骨料抗飞散性能。
3. At low temperature, the loss rate of the fly dispersion in the low-temperature Kent tower is about 1/2, which has excellent anti-flying performance of the aggregate.
4、良好的变形追从性,抗裂性能优异。
4. Good shape-shifting and anti-cracking performance.
5、沥青高粘剂在拌和的过程中受高温的作用软化后,与沥青和集料充分结合并填充嵌挤到级配骨架的空隙中,限制了矿料颗粒间的相对滑动,加强了混合料之间的相互作用力,使混合料结构更加稳定。
5, asphalt, high adhesive in the process of mixing the role of softening under high temperature, and combination of asphalt and aggregate and populate the embedded into the gap gradation skeleton, limit the relative sliding between the mineral aggregate particles, strengthen the interaction between mixture and mixture structure is more stable.
