Description

technical field [0001] The application belongs to the technical field of materials, and in particular relates to a greenway pavement material and a preparation method. Background technique [0002] Environmental protection travel has gradually become one of the main choices of modern people's life. More and more cities have joined the ranks of the construction of "Wanli Green Road". The quality and functionality of the slow travel system have gradually attracted the attention of the public. At this stage, common urban greenway pavement materials mainly include: hot-mix colored asphalt concrete, permeable cement concrete, cold-mix resin concrete, and colored surface coating. Among them, hot-mix colored asphalt concrete is suitable for large-area construction and has good flatness. The main disadvantages include: easy fading, poor color stability, easy water damage, and impermeability. Permeable cement concrete is low in cost and easy to construct. The main disadvantages incl...
