改性沥青的改性工艺： Modification process of modified asphalt: 将改性剂、助剂均匀、精细地分散到基质沥青中，尽可能增加原沥青与改性剂的接触面积，保证充分融胀、发育，既提高了改性剂的利用率又使原沥青性能得到最完美改善。 The modified agent evenly and finely dispersed into the matrix asphalt, the contact area as much as possible to increase the original asphalt and modifier, to ensure full financial expansion, development, not only improves the utilization rate of the modifier and the original asphalt performance perfectly improved. 改性沥青的改性原理： Modification principle of modified asphalt: 沥青是由沥青质、胶质、芳烃和饱和烃组成的高分子混合物，沥青质借助胶质分散在芳烃和饱和烃中，形成胶体结构，沥青质含量少时，沥青的粘结性、塑性、流动性较好，吸附了沥青中的芳烃和胶质，形成新的胶体，这样既保留或增加了原沥青的粘结性、塑性和流动性又改善了沥青的温度稳定性和弹性，从而达到提高沥青路用性能的目的。 The polymer is asphalt mixture composed of asphaltene, aromatics and saturated hydrocarbons, asphaltenes with colloid dispersed in aromatics and saturated hydrocarbons, the formation of colloidal structure, asphaltene content is low, the asphalt adhesion, plasticity, good fluidity, adsorption of asphalt in aromatics and resins, the formation of a new colloid so, retain or increase the original asphalt adhesion, plasticity and fluidity and improve asphalt temperature stability and flexibility, so as to achieve the purpose to improve the performance of asphalt pavement.
