Temperature-control high-performance solid waste asphalt concrete
The invention provides temperature-control high-performance solid waste asphalt concrete, and belongs to the technical field of asphalt concrete. Raw materials of the temperature-control high-performance solid waste asphalt concrete comprise the following components in parts by weight: 68-74 parts of coarse aggregate, 8-11 parts of fine aggregate, 6.5-7 parts of modified asphalt, 9-13 parts of mineral powder, 8-12 parts of phase-change microcapsules, 0.3-0.5 part of lignin fibers, 0.3 part of a dispersing agent and 1-1.5 parts of an adhesive, wherein the modified asphalt is prepared from the following raw material components in parts by weight: 100 parts of matrix asphalt, 4 parts of SBS (Styrene Butadiene Styrene), 3-4 parts of nano ZnO, 1.5-2 parts of a surfactant and 0.2-0.3 part of a plasticizer. The invention has the beneficial effects that the phase change microcapsule is mainly used, and the temperature is regulated and controlled through phase state conversion, energy absorption or energy release, so as to weaken the heat damage of high temperature to the asphalt concrete, improve the bearing capacity and the stability of the pavement and the rutting resistance.
本发明提供了一种控温高性能固废沥青混凝土，属于沥青混凝土技术领域。其原料按照重量份计，包括以下组分：粗集料68‑74份、细集料8‑11份、改性沥青6.5‑7份、矿粉9‑13份、相变微胶囊8‑12份、木质素纤维0.3‑0.5份、分散剂0.3份、胶粘剂1‑1.5份；其中改性沥青其原料按照重量份计，包括以下组分：基质沥青100份、SBS4份、纳米ZnO 3‑4份、表面活化剂1.5‑2份、增塑剂0.2‑0.3份；本发明的有益效果主要是以相变微胶囊的使用，通过相态的转化，吸收或释放能量，达到对温度的调控，以减弱高温对沥青混凝土产生的热损害；提高路面的承载力和稳定性，提高抗车辙能力。
