Pouring type modified asphalt and pouring type modified asphalt concrete
The invention discloses pouring type modified asphalt and pouring type modified asphalt concrete, and belongs to the technical field of civil engineering pavement paving. The problems that in the prior art, pouring type asphalt is insufficient in high-temperature performance and high in viscosity at the high-temperature mixing temperature are solved. The pouring type modified asphalt provided by the invention comprises the following raw materials in parts by weight: 100 parts of matrix asphalt, 4-12 parts of a polymer modifier, 2-10 parts of a plastomer, 1-5 parts of a viscosity reducer, 3-12 parts of softening oil, 0.1-2 parts of a coupling agent and 0.1-0.5 part of a heat stabilizer. The pouring type modified asphalt concrete provided by the invention is composed of the following raw materials in parts by weight: 75-90 parts of graded aggregate, 10-25 parts of mineral powder, 4-10 parts of pouring type modified asphalt and 1-4 parts of hard asphalt. The pouring type modified asphalt provided by the invention has excellent high-temperature performance and low-temperature performance, the viscosity of the asphalt is relatively low at the high temperature of 220 DEG C, and a pouring type asphalt mixture is easier to produce.
本发明公开了一种浇注式改性沥青及浇注式改性沥青混凝土，属于土木工程路面铺装技术领域。解决了现有技术中浇注式沥青高温性能不足以及高温拌和温度下粘度较高的问题。本发明提供的浇注式改性沥青包括以下重量分的原料：基质沥青100份、聚合物改性剂4～12份、塑性体2～10份、降粘剂1～5份、软化油3～12份、偶联剂0.1～2份、热稳定剂0.1～0.5份。本发明提供的浇注式改性沥青混凝土，包含以下重量份的原料：级配骨料75～90份、矿粉10～25份、浇注式改性沥青4～10份、硬质沥青1～4份。本发明提供的浇注式改性沥青具有优异的高温性能和低温性能，且高温220℃下沥青粘度较低，更易于生产浇注式沥青混合料。
