Design method of asphalt mixture, noise reduction asphalt preparation method, system and application
The invention discloses a design method of an asphalt mixture, a noise-reducing asphalt preparation method, a system and application. The design method comprises the steps that skeleton gap type diabase is selected as stone, and the particle size distribution range of the stone is at least two grades of gradation of 0-n1 and n2-n3; other gradations except 0-n1 in the stone are used as coarse aggregates; measuring the synthetic compact density and the synthetic gross volume relative density of the coarse aggregate, and calculating the void rate of the coarse aggregate; calculating the use amount of the mineral powder to be supplemented and the target void ratio; calculating to obtain the ratio of the coarse aggregate to the fine aggregate; obtaining new fine aggregates and new coarse aggregates based on the particle size distribution range of the medium aggregates; drawing up the oil film thickness h, calculating the specific surface area A of the aggregate, and then calculating the amount of asphalt; calculating respective asphalt-aggregate ratios, and selecting design gradation according to the void ratio; and preparing the asphalt mixture according to the designed gradation. According to the scheme, the problems that existing asphalt is single in performance and difficult to have noise reduction performance and other performance at the same time are solved.
沥青混合料的设计方法、降噪沥青制备方法、系统和用途；设计方法，包括步骤：选择骨架空隙型的辉绿岩作为石料，石料的粒径分布范围为0‑n1和n2‑n3的至少两档级配；以石料中的0‑n1以外的其他级配作为粗集料；测量粗集料的合成紧装密度和合成毛体积相对密度，计算粗集料间隙率；计待补加的矿粉用量和目标空隙率；计算获得粗集料和细集料的比例；基于中集料的粒径分布范围，获得新的细集料和新粗集料；拟定油膜厚度h，计算集料比表面积A，再计出沥青用量；计算出各自的油石比，根据空隙率选择设计级配；按设计级配制备沥青混合料。本方案解决了现有的沥青性能单一，难以兼备降噪性能和其他性能的问题。
