High-strength asphalt concrete and preparation method thereof
The invention discloses a high-strength asphalt concrete and a preparation method thereof, and relates to the technical field of asphalt concretes. The high-strength asphalt concrete comprises 250-300parts of aggregate, 25-50 parts of asphalt, 3-8 parts of an adhesive, 10-25 parts of mineral powder, 1.5-2.5 parts of lignocellulose, 0.5-1 part of chitin, 1-2 parts of a dispersant, 1-3 parts of silicon nitride and 1-2 parts of porous ceramic. The preparation method comprises the following steps: S1, putting the aggregate into a drying barrel, stirring and drying, adding the adhesive, the mineral powder, the silicon nitride, the porous ceramic and the lignocellulose, and continuously and uniformly mixing to obtain a mixed base material; S2, heating asphalt to 155-200 DEG C, putting the asphalt into a stirring cylinder in step S1, and uniformly stirring; and S3, adding chitin and the dispersant into the stirring cylinder in step S2, uniformly stirring, and discharging to obtain the product. The asphalt concrete disclosed by the invention has the advantages of high structural strength and long service life of an asphalt concrete pavement.
本发明公开了一种高强度沥青混凝土及其制备方法，涉及沥青混凝土技术领域。其技术要点是：该高强度沥青混凝土包括集料250‑300份；沥青25‑50份；胶黏剂3‑8份；矿粉10‑25份；木质纤维素1.5‑2.5份；甲壳素0.5‑1份；分散剂1‑2份；氮化硅1‑3份；多孔陶瓷1‑2份。其制备方法为：S1，将集料投入烘干桶内，搅拌烘干，并加入胶黏剂、矿粉、氮化硅、多孔陶瓷和木质纤维素，继续混合均匀，得到混合基料；S2，将沥青加热至155‑200℃，并投入S1中的搅拌缸中，搅拌均匀；S3，在S2的搅拌缸中加入甲壳素和分散剂，搅拌均匀，出料即得。本发明中的沥青混凝土具有较高的结构强度，沥青混凝土路面使用寿命较长的优点。
