一种高性能温拌再生沥青混合料制备方法
摘要：
本发明公开了一种高性能温拌再生沥青混合料制备方法,其实施步骤如下，先对旧沥青混合料进行抽提筛分，确定混合料的级配和沥青含量，并对沥青进行三大指标试验，评定RAP中旧沥青性能指标；再根据RAP中沥青的性能指标来确定RAP的掺量比例，一般可在50%～100%范围内选取，RAP中沥青性能指标越好，掺量可以越高；再按常规沥青混合料的马歇尔“5点法”确定沥青混合料的最佳外掺新沥青用量（OACn）；将计算出外掺新沥青用量后，根据《沥青路面施工技术规范》（JTGF40-2004）中规定的性能指标按照《公路工程沥青及沥青混合料试验规程》（JTGE20-2011）中规定的试验方法进行检测。
摘要（英）：

The invention discloses a preparation method of a high-performance warm-mix regenerated asphalt mixture, which comprises the following steps: extracting and screening an old asphalt mixture, determining the size distribution and asphalt content of the mixture, carrying out three-main-index testing on the asphalt, and evaluating old asphalt performance indexes in RAP; determining the doping proportion of the RAP according to the performance indexes of the asphalt in the RAP, wherein the doping proportion is generally 50-100%, and the doping proportion can be higher as the performance indexes of the asphalt in the RAP are higher; determining the optimal doped new asphalt consumption (OACn) of the asphalt mixture by a conventional asphalt mixture Marshall five-point process; and after calculating the doped new asphalt consumption, detecting according to according to the performance indexes specified in Asphalt Pavement Construction Technique Specifications (JTGF40-2004) by a testing method specified in Highway Engineering Asphalt and Asphalt Mixture Test Specifications (JTGE20-2011).
