Emulsified asphalt mixture and preparation method thereof
The invention belongs to the technical field of emulsified asphalt materials, and particularly relates to an emulsified asphalt mixture and a preparation method thereof.The emulsified asphalt mixture is prepared from 95-98 parts of aggregate, 3-5 parts of early strength agent, 0-2 parts of water, 0-3 parts of mineral powder and 10-11 parts of modified emulsified asphalt, the modified asphalt is obtained by compounding and modifying SBS, petroleum resin and rubber powder. Through step-by-step preparation, the mixture has good emulsifying performance and can emulsify SBS and rubber powder, SBS, petroleum resin and rubber powder are organically combined, the mixture has good performance, meanwhile, the early strength agent is used, the early strength agent and modified emulsified asphalt can play a synergistic effect, the performance of the mixture is further improved, and the service life of the mixture is prolonged. All performance indexes of the emulsified asphalt mixture reach or even exceed those of a hot-mix asphalt mixture, and the emulsified asphalt mixture can be applied to a surface layer of an asphalt pavement and has very high actual use value.
本发明属于乳化沥青材料技术领域，具体涉及一种乳化沥青混合料及其制备方法，该混合料包括95～98份集料、3～5份早强剂、0～2份水、0～3份矿粉和10～11份改性乳化沥青，其中乳化沥青包括改性沥青、水、阳离子乳化剂及H调节剂，改性沥青由SBS、石油树脂和橡胶粉复合改性所得。通过分步制备，使该混合料具有很好的乳化性能，能够乳化SBS和橡胶粉，将SBS、石油树脂和橡胶粉有机的结合起来，使混合料具有很好的性能，同时使用早强剂，早强剂与改性乳化沥青能够发挥协同作用，进一步提高混合料的性能，使本发明中乳化沥青混合料各项性能指标达到甚至超过了热拌沥青混合料，能够应用在沥青路面的面层，具有很强的实际使用价值。
