Asphalt concrete with good rutting resistance and preparation method thereof
The invention relates to the technical field of asphalt concrete, and particularly discloses asphalt concrete with good rutting resistance, which is prepared from the following raw materials in parts by mass: 100 to 150 parts of asphalt, 10 to 30 parts of cement, 20 to 40 parts of silica fume, 10 to 50 parts of quartz sand, 5 to 15 parts of nano calcium carbonate, 1 to 2 parts of silane coupling agent, 10 to 30 parts of branched lignin, 1 to 10 parts of organic fiber, 1 to 10 parts of inorganic fiber and 1 to 5 parts of anti-stripping agent. The branched lignin is obtained by acetylating lignin and then grafting the acetylated lignin with palmitic acid and nano graphene oxide. The invention also discloses a preparation method of the asphalt concrete with good rut resistance. According to the invention, under the cooperation of branched lignin, nano calcium carbonate is filled in asphalt gaps, and under the cooperation of cement, the integrity of an asphalt concrete system is enhanced, the deformation modulus of the asphalt concrete is effectively improved, the anti-rutting performance of the system is good, and the service life of the asphalt concrete can be effectively prolonged.
本发明涉及沥青混凝土技术领域，具体公开了一种抗车辙能力好的沥青混凝土，其原料按质量份包括：沥青100‑150份，水泥10‑30份，硅灰20‑40份，石英砂10‑50份，纳米碳酸钙5‑15份，硅烷偶联剂1‑2份，支化木质素10‑30份，有机纤维1‑10份，无机纤维1‑10份，抗剥落剂1‑5份；支化木质素采用木质素进行乙酰化后，再与棕榈酸、纳米氧化石墨烯接枝得到。本发明还公开了上述抗车辙能力好的沥青混凝土制备方法。本发明经支化木质素的配合下，纳米碳酸钙填充在沥青间隙内，配合水泥作用，加强沥青混凝土体系整体性，有效地提高沥青混凝土的形变模量，体系抗车辙性能好，同时可以有效延长沥青混凝土的使用寿命。
