| 针对国家近年大力提倡推广建设的排水沥青路面、彩色透水沥青路面来说，沥青混合料属于开级配，孔隙率大，粗集料多，细集料少，颗粒之间不能形成强有力的嵌锁作用，混合料的强度主要依靠结合料的粘结作用，所以这时候添加高粘度添加剂这种材料正可谓是对症下药，掺加高粘度添加剂后的沥青混合料具有很高的抗飞散性、耐水性、耐候性和耐流动性，可以大幅提高沥青混凝土的各项性能，进而有效延长路面使用寿命。 In view of the drainage asphalt pavement and color pervious asphalt pavement that our country has vigorously advocated in recent years, asphalt mixture belongs to open gradation, with large porosity, more coarse aggregates and less fine aggregates. It can not form a strong interlocking effect between particles. The strength of mixture mainly depends on the bonding effect of binder, so adding high hugan.37ix.com.cngxianwei.37ix.com.cndiaosuoju.37ix.com.cnhandan.37ix.com.cnviscosity additives at zhongyaoji.37ix.com.cntongdiaopin.71ix.comthis time can be said to be the material. The asphalt mixture mixed with high viscosity additives has high dispersion resistance, water resistance, weather resistance and fluidity resistance, which can greatly improve the performance of asphalt concrete and effectively prolong the service life of pavement. 那么如何来判断高粘度添加剂的质量呢？主要是通过一定比例把高粘度添加剂加入到70#或90#基质沥青进行融化，融化后的沥青运动粘度能否大于5万pa.s,这是判断高粘度添加剂最重要的方法，掺量越低，粘度越高，高粘度添加剂质量就越好。 So how to judge the quality of high viscosity additives? It is the most important method to judge whether the kinematic viscosity of the melted asphalt is greater than 50,000 Pa.s by adding high viscosity additives to 70 # or 90 # base asphalt in a certain proportion. The lower the content of the additives, the higher the viscosity, the better the quality of the high viscosity additives. |
