多蜡沥青又称橡皮沥青,是石油工业的主要副产品。外观呈灰褐色,稜角不整齐,质软,富弹性。同10号沥青相比,其软化点高,针入度大,性好,抗冻性强,粘结性差,故不能在建筑工程中单独使用。目前由于10号沥青产量较少,不能满足日益发展的基本建设需要;而多蜡沥青随着石油工业的飞跃发 Multi-wax asphalt, also known as rubber asphalt, is a major by-product of the petroleum industry. The appearance of gray brown, angular corners, soft, flexible. Compared with bitumen No. 10, the softening point is high, the penetration is large, the properties are good, the frost resistance is strong, and the adhesion is poor, so it cannot be used alone in a construction project. At present, due to the low output of No. 10 asphalt, it cannot meet the growing needs of the basic construction; and the multi-wax asphalt has become a major leap forward with the oil industry.
