Composite fiber emulsified asphalt mixture and preparation method thereof
The invention discloses a composite fiber emulsified asphalt mixture. The composite fiber emulsified asphalt mixture comprises emulsified asphalt, aggregate, a curing agent, calcium hydroxide and fibers, wherein the emulsified asphalt accounts for 6-8% of the aggregate in percentage by mass; wherein the content of calcium hydroxide is 2-3% of the mass of the aggregate; the mineral powder accountsfor 6.5-8.5% of the mass of the aggregate; the curing agent accounts for 3-5% of the mass of the emulsified asphalt; and the fiber accounts for 0.2-0.3% of the mass of the aggregate. In addition, theinvention further discloses a preparation method of the composite fiber emulsified asphalt mixture. The composite fiber emulsified asphalt mixture is high in shear resistance, cracks and track diseases of an asphalt pavement can be reduced, the capillary phenomenon of fibers is adopted, moisture on the surface and inside the mixture can be rapidly volatilized, and the early strength of the mixtureis improved.
本发明公开了一种复合纤维乳化沥青混合料，其包括：乳化沥青、集料、固化剂、氢氧化钙以及纤维；其中，所述乳化沥青占集料的质量百分比为6‑8％；氢氧化钙含量为集料质量的2‑3％；所述矿粉占所述集料质量的6.5～8.5％；所述固化剂占所述的乳化沥青质量的3‑5％；所述纤维占所述集料质量的0.2～0.3％。此外，本发明还公开了上述的复合纤维乳化沥青混合料的制备方法。该复合纤维乳化沥青混合料的抗剪性能高,可减少沥青路面的裂缝与车辙病害的产生，其采用纤维的毛细现象，使得混合料表面以及内部水分能够快速挥发，提高混合料早期强度。
