SMA-13 hot in-place recycling asphalt mixture and preparation method thereof
The invention discloses an SMA-13 hot in-place recycling asphalt mixture and a preparation method thereof. Fibers have good dispersibility in the asphalt mixture, and the hot in-place recycling asphalt mixture has good performance. The SMA-13 hot in-place recycling asphalt mixture disclosed by the invention comprises the following components in percentage by mass: 20-30% of a fresh mixed asphalt mixture, and 70%-80% of a milling material. The hot in-place recycling asphalt mixture is graded by adopting SMA-13. The preparation method of the SMA-13 hot in-place recycling asphalt mixture comprises the steps of melting modified asphalt, preheating mineral aggregates, preheating milling materials, mixing the milling materials, preparing a fresh mixed asphalt mixture and preparing a finished product.
本发明公开一种SMA‑13就地热再生沥青混合料及其制备方法。纤维在沥青混合料中的分散性好，就地热再生沥青混合料性能好。本发明的SMA‑13就地热再生沥青混合料，其组成及质量百分含量为：新拌沥青混合料，20％～30％；铣刨料，70％～80％；所述就地热再生沥青混合料采用SMA‑13级配。本发明的SMA‑13就地热再生沥青混合料制备方法包括：改性沥青熔融、矿料预热、铣刨料预热、铣刨料拌和、新拌沥青混合料制备和成品制备步骤。
