High-dosage TB rubber modified asphalt mixture and preparation method thereof
The invention discloses a high-dosage TB rubber modified asphalt mixture, which is prepared from the following raw materials in parts by weight: 4.0 to 6.0 parts of TB rubber modified asphalt, 2 to 4 parts of rubber particles, 0.3 to 0.5 part of waste edible oil, 8 to 12 parts of mineral powder and 75 to 85 parts of aggregate, the TB rubber modified asphalt comprises the following raw materials in percentage by weight: 20-40% of rubber powder, 6-8% of waste edible oil and the balance of matrix asphalt, the particle size of the rubber particles is larger than that of the rubber powder. According to the invention, the problems of overhigh viscosity, low mixing amount of rubber powder, damage caused by volume expansion after paving and compacting and the like during mixing of the rubber asphalt at present can be effectively solved, so that the high-mixing-amount TB rubber modified asphalt mixture is simpler and more convenient to construct, and the construction difficulty is reduced.
本发明公开了高掺量TB橡胶改性沥青混合料，包括如下重量份的原料：TB橡胶改性沥青4.0～6.0份、橡胶颗粒2～4份、废食用油0.3～0.5份、矿粉8～12份、集料75～85份；所述TB橡胶改性沥青包括如下重量百分比的原料：橡胶粉20～40％、废食用油6～8％，余量为基质沥青；所述橡胶颗粒的粒径大于橡胶粉的粒径。本发明可有效解决目前橡胶沥青拌合时粘度过大、橡胶粉掺量较低、摊铺压实后体积膨胀导致破坏等问题，使高掺量TB橡胶改性沥青混合料施工时更加简便，施工难度降低。
