High-viscosity and high-elasticity asphalt with stable heat storage as well as preparation method and application of high-viscosity and high-elasticity asphalt
The invention discloses high-viscosity and high-elasticity asphalt with stable heat storage as well as a preparation method and application thereof, and belongs to the technical field of modified asphalt. The preparation method of the high-viscosity and high-elasticity asphalt comprises the following steps: heating and drying the matrix asphalt, then adding the SBS modifier, the hydrophobic nano-material, the polymer interface enhancer and the aromatic supplement, and carrying out pre-swelling; heating the pre-swelled asphalt system to 180-190 DEG C, and carrying out high-speed shearing; cooling the sheared asphalt system, stirring and developing; and then adding a cross-linking agent, and maintaining the stirring development condition to obtain the high-viscosity and high-elasticity asphalt. Through combination of physical compatibilization and chemical compatibilization, the problem of poor thermal storage stability of the high-viscosity and high-elasticity asphalt is solved, and the prepared high-viscosity and high-elasticity asphalt has excellent pavement performance, can well meet the technical characteristics of ultrathin overlay engineering and technical index requirements of cementing materials, and has wide application prospects. Therefore, the method has important application value in the technical field of thin overlay engineering.
本发明公开了一种热存储稳定的高粘高弹沥青、其制备方法及应用，属于改性沥青技术领域。所述高粘高弹沥青的制备方法，步骤如下：将基质沥青加热烘化，然后加入SBS改性剂、疏水性纳米材料、聚合物界面增强剂和芳香分补充剂，进行预溶胀；将预溶胀完的沥青体系加热至180～190℃，进行高速剪切；将剪切完的沥青体系降温，搅拌发育；然后加入交联剂，维持上述搅拌发育条件，获得高粘高弹沥青。本发明通过物理增容和化学增容联用解决了高粘高弹沥青热存储稳定性差的问题，由此制备的高粘高弹沥青，路用性能优异，能够很好地满足超薄罩面工程技术特点和胶结料技术指标要求，从而在薄层罩面工程技术领域具有重要应用价值。
