Permeable emulsified asphalt concrete and preparation method thereof
The invention discloses permeable emulsified asphalt concrete and a preparation method thereof. The permeable emulsified asphalt concrete is prepared from the following components in parts by mass: 50-70 parts of coarse aggregate, 20-25 parts of cement, 5-10 parts of modified emulsified asphalt, 0-5 parts of a cementing agent and 5-10 parts of water, wherein the modified emulsified asphalt is prepared from the following components in parts by mass: 40-60 parts of asphalt, 20-30 parts of anionic emulsion, 20-25 parts of rubber powder and 0-5 parts of an anti-stripping agent. The prepared modified emulsified asphalt is suitable for low-temperature storage, and the prepared permeable emulsified asphalt concrete has the advantages of high concrete strength, high-temperature rutting resistance and wear resistance.
本发明公开了一种透水乳化沥青混凝土及其制备方法，是由以下各组分按质量份比配比制备而成：粗集料50‑70份、水泥20‑25份、改性乳化沥青5‑10份、胶结剂0‑5份、水5‑10份；其中，改性乳化沥青是由以下各组分按质量份比配比制备而成：沥青40‑60份，阴离子乳液20‑30份，橡胶胶粉20‑25份，抗剥落剂0‑5份。本发明制备得到的改性乳化沥青适用于低温储藏，制备得到的改透水乳化沥青混凝土具有高混凝土强度、高温抗车辙性能和耐磨性的优点。
