Asphalt mixture modified by waste plastic-based additive and preparation method of asphalt mixture
The invention discloses a waste plastic-based additive modified asphalt mixture and a preparation method thereof. The preparation method of the waste plastic-based additive comprises the following steps: crushing a bottle body material of a waste plastic bottle to obtain a plastic bottle sheet; and reacting the plastic bottle sheets with triethylene tetramine, and purifying and crushing the reacted system in sequence to obtain the waste plastic-based additive. Bottle body materials of common waste plastic bottles in life are used as raw materials, the bottle body materials are polyester, and the polyester is purified and ground into powder after being subjected to ammonolysis to obtain the waste plastic-based additive. The waste plastic-based additive is used as an asphalt modifier to prepare modified asphalt, the modified asphalt is used for preparing an asphalt mixture, and strong physical and chemical effects such as electrostatic adsorption, chemical bonding, hydrogen bonding and acid-base neutralization can be formed between the modified asphalt and acidic aggregate; the anti-stripping performance and the water stability of the asphalt mixture are greatly improved.
本发明公开一种废弃塑料基添加剂改性的沥青混合料及其制备方法。其中废弃塑料基添加剂的制备方法，包括步骤：将废弃塑料瓶的瓶身材料进行破碎处理，得到塑料瓶薄片；将所述塑料瓶薄片与三乙烯四胺进行反应，将反应后体系依次进行纯化和粉碎后，得到废弃塑料基添加剂。本发明以生活中常见的废弃塑料瓶的瓶身材料作为原料，该瓶身材料为聚酯，聚酯通过氨解作用后，经纯化、磨粉得到废弃塑料基添加剂。采用该废弃塑料基添加剂作为沥青改性剂，制备改性沥青，采用该改性沥青制备沥青混合料，该改性沥青与酸性集料之间可以形成很强的静电吸附、化学键合、氢键结合与酸碱中和等物理化学作用，大大提高了沥青混合料的抗剥落性和水稳定性。
