Cast asphalt dry modifier, dry modified cast asphalt mixture and preparation method
The invention discloses a cast asphalt dry modifier, a dry modified cast asphalt mixture and a preparation method. The dry modified cast asphalt mixture is prepared by mixing a mineral aggregate, No.A-70 road petroleum asphalt and a cast asphalt dry modifier according to the mass ratio of 100: (6.0-7.5): (0.7-1.5), wherein the cast asphalt dry modifier is obtained by mixing a styrene thermoplastic elastomer, thermoplastic resin, a viscosity reducer, a high-temperature reinforcing agent and a pre-swelling agent according to the mass ratio of (40-70): (5-40): (5-20): (5-20): (5-15). The prepared dry modified cast asphalt mixture has the advantages of being easy and convenient to operate, stable and reliable in quality, capable of saving energy, environmentally friendly and the like, the quality of small-area maintenance of steel bridge deck pavement pits and the like can be effectively guaranteed, the durability of steel bridge deck pavement is improved, and the service life of steel bridge deck pavement is prolonged.
本发明公开了浇注式沥青干法改性剂、干法改性浇注式沥青混合料及制备方法，其中，所述干法改性浇注式沥青混合料由矿料、A‑70号道路石油沥青和浇注式沥青干法改性剂以100:(6.0～7.5):(0.7～1.5)的质量比混合而成，所述浇注式沥青干法改性剂由苯乙烯类热塑性弹性体、热塑性树脂、降黏剂、高温补强剂和预溶胀剂以(40～70):(5～40):(5～20):(5～20):(5～15)的质量比混合而成。本发明制备的干法改性浇注式沥青混合料，具有操作简单便捷、质量稳定可靠、节能环保等特点，可有效保障钢桥面铺装坑槽等小面积维修的质量，提升钢桥面铺装的耐久性能与服役寿命。
