Process for preparing asphalt from waste concrete
The invention relates to the technical field of waste concrete recycling, and discloses a process for preparing asphalt from waste concrete, which comprises the following steps of: researching the crushing value, the abrasion rate and the asphalt adhesion property of waste concrete recycled aggregate: researching the crushing value and the abrasion rate of the concrete recycled aggregate through crushing value and abrasion rate tests; and testing and researching the adhesion performance of the concrete recycled aggregate and the asphalt through a water boiling method, and the like. According to the invention, the influence of the technical indexes, variability and pretreatment process of the recycled coarse aggregate on the technical indexes and the influence of the recycled coarse aggregate on the design and pavement performance of the asphalt concrete are researched, so that a test basis is provided for applying the recycled coarse aggregate to the asphalt concrete; and a test basis is provided for formulating related technical standards of the recycled aggregate for the asphalt concrete.
本发明涉及废弃混凝土再利用技术领域，并公开了一种废弃混凝土制备沥青工艺，包括对废弃混凝土再生骨料压碎值、磨耗率以及与沥青粘附性能进行研究:通过压碎值和磨耗率试验，研究混凝土再生骨料的压碎值及磨耗率；通过水煮法试验研究混凝土再生骨料与沥青粘附性能等步骤。本发明通过对再生粗骨料的技术指标、变异性、预处理工艺对其技术指标的影响，以及再生粗骨料对沥青混凝土设计、路用性能的影响进行研究，为再生粗骨料应用于沥青混凝土提供试验依据，为制定沥青混凝土用再生骨料的相关技术标准提供试验依据。
