Colored asphalt mixture additive and colored warm-mix mixture, and preparation methods thereof
The invention relates to a colored asphalt mixture additive and a colored warm-mix mixture, and preparation methods thereof. The invention aims to solve the problems that the color of a colored asphalt mixture produced by taking asphalt as a cementing material is not durable and the process for producing a high-performance colored asphalt mixture is complex. The colored asphalt mixture additive comprises the following components in percentage by mass: 75-85% of a pigment body, 5-15% of a polymer adhesive, 0.5-2% of a brightening agent and 8-15% of an ethylene-acetic acid polymer. The colored warm-mix mixture comprises warm-mix asphalt, graded stone, the colored asphalt mixture additive and lignin fibers. The preparation method of the colored warm-mix mixture comprises the following steps:adding a surfactant type warm mixing agent and asphalt into an asphalt storage tank, and carrying out circulating and stirring to obtain the warm-mix asphalt; carrying out dry mixing on the graded stone, the colored asphalt mixture additive and the lignin fibers; and after dry mixing is completed, adding the warm-mix asphalt and carrying out wet mixing so as to obtain the colored warm-mix mixtureafter wet mixing is completed.
本发明涉及彩色沥青混合料添加剂、彩色温拌混合料及其制备方法，以解决采用沥青作为胶结料生产的彩色沥青混合料存在色彩不持久、生产高性能彩色沥青混合料存在工艺复杂的问题。彩色沥青混合料添加剂包括质量分数为75‑85%的颜料本体，质量分数为5‑15%的聚合物粘合剂，质量分数为0.5‑2%的亮色剂，质量分数为8‑15%的乙烯‑醋酸聚合物。彩色温拌混合料包括温拌沥青、级配石料、彩色沥青混合料添加剂、木质素纤维。彩色温拌混合料制备方法，将表面活性剂型温拌剂和沥青添加至沥青储存罐并循环、搅拌，即得温拌沥青；将级配石料、彩色沥青混合料添加剂、木质素纤维进行干拌；干拌完成后添加温拌沥青进行湿拌，湿拌完成后即得彩色温拌混合料。
