Modified asphalt for steel bridge deck pavement and preparation method thereof
The invention discloses modified asphalt for steel bridge deck pavement, which is prepared from the following raw materials in parts by weight: based on 100 parts of matrix asphalt, 3-7 parts of thermoplastic elastomer, 1-5 parts of thermoplastic resin, 2-4 parts of plasticizer, 1-3 parts of aromatic hydrocarbon oil, 2-6 parts of self-repairing microcapsule, 5-15 parts of diatomite and 0.1-0.3 part of stabilizer. The self-healing ability of the steel bridge deck pavement material can be improved when cracks appear, and the steel bridge deck pavement material can be self-repaired by means of the excellent self-healing ability even if the cracks appear. Meanwhile, the anti-cracking performance of the steel bridge deck pavement material can be improved, cracking is delayed as much as possible, and the service life is prolonged.
本发明公开了一种钢桥面铺装用改性沥青，由如下重量份数的原料制备而成：以100份基质沥青计，包括3‑7份热塑性弹性体、1‑5份热塑性树脂、2‑4份增塑剂、1‑3份芳烃油、2‑6份自修复微胶囊、5‑15份硅藻土和0.1‑0.3份稳定剂。本发明能够提升钢桥面铺装材料在出现裂缝时自身的自愈合能力，即使出现开裂，也能靠自身优异的自愈合能力自我修复。同时，可以提升钢桥面铺装材料的抗开裂性能，尽可能延缓开裂，延长服役寿命。
