| 沥青高粘剂的优势 Advantages of high viscosity bitumen 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, the asphalt tackifier has a great influence on the shear strength: the shear strength of the adhesive layer rises first and then decreases with the increase of the thickness of the viscoelastic layer, and the peak value appears in the middle, and the position of the peak shear strength of different bonding layers 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 the high viscosity asphalt adhesive. Under high temperature, the shear and tensile properties of high viscosity asphalt are better than those of the other two kinds of viscoelastic 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, low temperature cantabro loss rate is about 1/2, with excellent anti flying aggregate. 4、良好的变形追从性，抗裂性能优异。 4, good deformation and good 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. In the process of mixing, the asphalt tackifier is softened by the effect of high temperature. It is fully combined with asphalt and aggregate and filled into the gap of the graded skeleton. It restricts the relative sliding between the ore particles, strengthens the interaction between the mixture and makes the mixture structure more stable. |
