High-cohesiveness emulsified asphalt and preparation method thereof
The invention discloses high-cohesiveness emulsified asphalt which is prepared from the following raw materials in parts by weight: 45-70 parts of asphalt, 1-5 parts of an emulsifier, 2-4 parts of a pH regulator, 0.1-0.7 part of an amine auxiliary and 25-52 parts of water, wherein the amine auxiliary comprises one of a compound containing amino and a derivative thereof, a compound containing acylamino and a derivative thereof and nitrogen heterocyclic alkaloid; according to the present invention, the amine auxiliary agent is added into the asphalt, such that the asphalt becomes wet and hydrophilic, the amine in the amino or amino-derived amine chemical and the hydrocarbon on the surface of the aggregate generate the conjugate so as to improve the adhesion between the aggregate and the asphalt, the process is simple, the raw materials are cheap and easily available, and the industrial production is easily achieved. The modified emulsified asphalt disclosed by the invention is used for pavements, has excellent high-temperature performance and water stability, improves the durability of roads, prolongs the service life of the pavements, and can be used in road base layers, middle surface layers and lower surface layers.
本发明公开了一种高粘结性乳化沥青，原料按重量份包括以下组分：沥青45‑70份、乳化剂1‑5份、pH调节剂2‑4份、胺类助剂0.1‑0.7份、水25‑52份，所述胺类助剂包括含有氨基的化合物及其衍生物、含有酰胺基的化合物及其衍生物、含氮杂环生物碱中的一种；将胺类助剂加入沥青当中，使沥青变的湿润亲水，氨基或者氨基衍生胺化学物中的胺和集料表面的碳氢生成结合物，从而提高集料与沥青间的粘附性，工艺简单，原料廉价易得，易工业化生产。将本发明的改性乳化沥青用于路面，具有优异的高温性能、水稳性能，提升道路的耐久性，延长路面的使用寿命，可在道路基层及中、下面层使用。
