High-modulus modified emulsified asphalt mixture and preparation method thereof
The invention discloses a high-modulus modified emulsified asphalt mixture and a preparation method thereof. The high-modulus modified emulsified asphalt mixture is prepared from the following components in percentage by mass: 8 to 12 percent of high-modulus emulsified asphalt, 0.5 to 1 percent of SBS (Styrene Butadiene Styrene) latex, 5 to 10 percent of mineral powder, 15 to 30 percent of coarse aggregate, 70 to 85 percent of fine aggregate, 1 to 3 percent of cement and 0.1 to 0.3 percent of polyester fiber. The high-modulus emulsified asphalt is produced through the hard asphalt particles, so that the modulus and high-temperature stability of the mixture are improved, the fatigue and low-temperature crack resistance of the mixture are improved through the linear SBS latex, a hard and tough three-dimensional network structure is formed by the hard asphalt and the SBS modifier, asphalt and aggregate are firmly locked, and the pavement performance is greatly improved.
本发明公开了一种高模量改性乳化沥青混合料及其制备方法，所述高模量改性乳化沥青混合料的组分包括：高模量乳化沥青8％～12％，SBS胶乳0.5％～1％，矿粉5％～10％，粗集料15％～30％，细集料70％～85％，水泥1％～3％，聚酯纤维0.1％～0.3％，以上比例均为质量比例。本发明通过硬质沥青颗粒生产高模量乳化沥青提升混合料的模量及高温稳定性能，通过线型SBS胶乳提升混合料的疲劳与低温抗裂性能，硬质沥青与SBS改性剂形成又硬又韧的三维网状结构，牢牢锁住沥青与集料，大幅提升路用性能。
