Self-healing drainage asphalt pavement blanket and preparation method thereof
The invention discloses a self-healing drainage asphalt pavement blanket and a preparation method thereof, and belongs to the technical field of asphalt materials of road engineering. The self-healing drainage asphalt pavement blanket is composed of self-healing high-viscosity and high-toughness modified asphalt and aggregate, the asphalt-aggregate ratio of the self-healing high-viscosity high-toughness modified asphalt to the aggregate is 5-6%; the self-healing type high-viscosity and high-toughness modified asphalt is prepared from the following raw materials in parts by mass: 75 to 80 parts of asphalt, 2 to 2.5 parts of self-healing microcapsules, 13 to 16 parts of an additive, 1.5 to 2 parts of a microwave high-sensitivity material and 1.5 to 2 parts of a Diels-Alder bond dynamic cross-linked network repairing agent. The self-healing drainage asphalt pavement blanket prepared by the invention is endowed with multiple thermal response synergistic self-healing ability on the premise of ensuring good drainage and noise reduction performance, the pavement performance of an asphalt drainage pavement is improved, and the service life of the asphalt drainage pavement is prolonged.
本发明公开了一种自愈型排水沥青路面毯及其制备方法，属于道路工程的沥青材料技术领域。所述自愈型排水沥青路面毯由自愈性高粘高韧改性沥青和集料组成；所述自愈型高粘高韧改性沥青与集料的油石比为5～6％；所述自愈型高粘高韧改性沥青的原料按质量份数计，包括：沥青75～80份、自愈合微胶囊2～2.5份、外加剂13‑16份、微波高敏感材料1.5～2份和Diels‑Alder键动态交联网络修复剂1.5～2份。本发明制备的自愈型排水沥青路面毯在保证其良好排水降噪性能的前提下，赋予多重热响应协同自愈合能力，提高沥青排水路面的路用性能及使用寿命。
