Modified asphalt for ultrathin overlay, asphalt mixture and interlayer treatment method
The invention relates to modified asphalt for an ultrathin overlay, an asphalt mixture and an interlayer treatment method. The modified asphalt comprises the following raw materials in parts by weight: 100 parts of matrix asphalt, 0.3-1.2 parts of micro carbon fibers, 3-8 parts of an SBS modifier, 0.1-0.5 part of a stabilizer, 1-5 parts of extract oil and 0.2-0.7 part of a warm mixing agent. The asphalt mixture is prepared from 6 to 7 parts of modified asphalt, 92 to 94 parts of aggregate and 0.2 to 0.6 part of cellulose. The high-temperature deformation resistance of the SBS modified asphalt is improved, and the viscosity and toughness index of the asphalt can be effectively improved; and the pavement performance requirement of the ultra-thin overlay is met.
本发明涉及一种超薄罩面用改性沥青、沥青混合料及层间处治方法。改性沥青包括如下重量份的原料基质沥青100份，微碳纤维0.3～1.2份，SBS改性剂3～8份，稳定剂为0.1～0.5份，抽出油1～5份，0.2～0.7份温拌剂。沥青混合料包括改性沥青6‑7份、集料92‑94份、纤维素0.2‑0.6份。提高SBS改性沥青高温抗变形能力，能够有效的改善沥青的黏韧性指标；满足超薄罩面的路用性能要求。
