High-viscosity high-elasticity anti-aging modified asphalt and preparation method thereof
The invention relates to the technical field of modified asphalt, in particular to high-viscosity high-elasticity anti-aging modified asphalt and a preparation method thereof. The invention provides high-viscosity high-elasticity anti-aging modified asphalt which comprises the following components in parts by mass: 100 parts of matrix asphalt, 7-13 parts of a high-viscosity high-elasticity agent and 3-8 parts of an anti-aging agent, wherein the high-viscosity and high-elasticity agent comprises 5-7 parts of thermoplastic styrene-butadiene rubber, 1-3 parts of polyurethane and 1-3 parts of lignin fiber. The modified asphalt provided by the invention not only has high viscosity and high elasticity, but also has anti-fatigue and anti-aging properties, and is also suitable for harsh environments such as high temperature or low temperature, and the service life of an asphalt pavement is greatly prolonged. Moreover, the preparation method of the high-viscosity high-elasticity anti-aging modified asphalt provided by the invention is simple, the construction time and the construction cost are greatly saved, and the construction efficiency is improved.
本发明涉及改性沥青技术领域，尤其涉及一种高粘高弹抗老化改性沥青及其制备方法。本发明提供一种高粘高弹抗老化改性沥青，按照质量份数计，包括基质沥青100份、高粘高弹剂7～13份和抗老化剂3～8份；其中，所述高粘高弹剂包括：热塑性丁苯橡胶5～7份，聚氨酯1～3份和木质素纤维1～3份。本发明提供的改性沥青既具有高粘高弹性能，又具有抗疲劳和抗老化性能，还适用于高温或低温等严酷环境，大大延长了沥青路面的使用寿命。而且，本发明提供的高粘高弹抗老化改性沥青的制备方法简单，大大节约了施工时间和施工成本，提高了施工效率。
