Design method of hot mix plant recycled asphalt mixture with high RAP proportion
The invention relates to the technical field of preparation of road building materials, in particular to a design method of a hot mix plant recycled asphalt mixture with a high RAP proportion, and the design method comprises the following steps: determining the basic performance of RAP, aggregate and new asphalt, obtaining the content and mark number of old asphalt in RAP, preliminarily determining the design grading type and the RAP mixing amount, then sequentially calculating to obtain a new asphalt mixing amount and a regenerant mixing amount, and completing a mix proportion design; then forming a Marshall test piece, and calculating volume parameters; forming a fatigue small beam and a rut plate, and conducting a fatigue test and a rut test; if the fatigue life or the dynamic stability is not qualified, adjusting the mix proportion design until the mix proportion design is qualified, determining the mix proportion design, and submitting a mix proportion design report. According to the method, whether the hot mix plant recycled asphalt mixture meets the current related regulations or not under the high-proportion RAP condition is rapidly determined, and the mixing amount of the RAP material in the hot mix plant recycled asphalt mixture is effectively increased.
本发明涉及道路建筑材料制备技术领域，特别涉及一种高比例RAP的厂拌热再生沥青混合料的设计方法，所述设计方法包括以下步骤：确定RAP、集料以及新沥青的基本性能，得到RAP中旧沥青的含量以及标号，并初步确定设计级配类型以及RAP掺量，然后依次计算得到新沥青掺量和再生剂掺量，完成配合比设计；然后成型马歇尔试件，计算体积参数；以及成型疲劳小梁及车辙板，进行疲劳试验和车辙试验；若疲劳寿命或动稳定度不合格时，调整配合比设计直至合格，确定配合比设计，并提交配合比设计报告；本发明实现了高比例RAP条件下厂拌热再生沥青混合料是否满足现行相关规定的快速确定，并有效地提高了厂拌热再生沥青混合料中RAP材料的掺量。
