作为一种建筑材料,乳化沥青必须具备一定的物理性能才能满足工程建设的需要,如粘度、贮存稳定性、同骨料的粘附能力等。其性能在不同的工程中有不同的要求,为此各工程系统制定了不同的质量标准。公路工程是乳化沥青用量最大的工程,下面就对路用乳化沥青的质量问题作一些简单介绍。一、路用乳化沥青的种类路用乳化沥青有阴离子型、阳离子型、非离子型三类。阴离子型的优点是材料来源广,造价低,缺点是怕硬水,粘结力较差。阳离子
As a building material, emulsified asphalt must have certain physical properties to meet the needs of construction, such as viscosity, storage stability, with the aggregate adhesion capacity. Its performance in different projects have different requirements, for which the engineering system developed a different quality standards. Highway engineering is the largest amount of emulsified asphalt project, the following on the road with the quality of emulsified asphalt to make some brief introduction. First, the road with emulsified asphalt Road with emulsified asphalt anionic, cationic, non-ionic three categories. Anion advantage is the wide source of raw materials, low cost, the disadvantage is afraid of hard water, poor adhesion. cation
