Asphalt concrete waste regeneration treatment process
The invention relates to the technical field of concrete waste regeneration treatment, and discloses an asphalt concrete waste regeneration treatment process which comprises the following steps: step 1, crushing and screening waste asphalt concrete waste to form a waste fine material and a waste coarse material; 2, 20-35 parts of new aggregate and 30-50 parts of new asphalt are added into the stirring kettle, and heating and stirring are conducted for 1 min; according to the invention, the modifier is added in the preparation process of the recycled concrete, and the rubber powder in the modifier increases the viscosity and elasticity of asphalt, reduces cracks caused by temperature change, and improves the flexibility and crack resistance of the recycled asphalt concrete; the polyester fibers can form a net-shaped structure in the recycled asphalt concrete, so that the integrity and durability of the recycled asphalt concrete are improved; the anti-stripping agent can further improve the cold resistance, heat resistance, crack resistance and weather resistance of the recycled concrete, so that the quality of the recycled concrete is greatly improved.
本发明涉及混凝土废料再生处理技术领域，且公开了一种沥青混凝土废料再生处理工艺，按如下步骤进行：步骤一：将废旧沥青混凝土废料进行破碎和筛分处理，形成废旧细料和废旧粗料；步骤二：添加新集料20‑35份和新沥青30‑50份进入搅拌釜内，加热搅拌1min。本发明通过在再生混凝土制备过程中添加改性剂，改性剂中的橡胶粉增加沥青的粘性和弹性，减少温度变化引起的裂缝，提高再生沥青混凝土的柔韧性和抗裂性能；聚酯纤维可以在再生沥青混凝土中形成网状结构，提高其整体性和耐久性；抗剥落剂能够进一步的提高再生混凝土的耐寒性、耐热性、抗裂性和耐候性，从而使得再生混凝土的质量得到极大提升。
