针对大比例温再生沥青混合料施工温度确定方法研究不足的现状,通过黏温曲线法、黏温曲线计算法及等体积法分别确定掺加两种温拌剂的RAP掺量为52%的再生沥青混合料的施工温度,结果表明黏温曲线法与黏温曲线计算法不适用于大比例温再生沥青混合料的施工温度确定。采用等体积法确定的掺M-1温拌剂的大比例温再生沥青混合料降温幅度约为10℃,掺Sasobit温拌剂的降温幅度约为18℃。按照等体积法成型的温再生沥青混凝土具有优良的高温性能、低温性能与水稳性能,均满足规范要求。
Aiming at the lack of research on the method for determining the construction temperature of large-scale warm recycled asphalt mixture, the RAP content of 52% was determined by the viscosity-temperature curve method, the viscosity-temperature curve calculation method and the isometric method, respectively Asphalt mixture construction temperature, the results show that the viscosity temperature curve method and the viscosity curve calculation method is not suitable for a large proportion of temperature regeneration asphalt mixture construction temperature determination. The temperature reduction range of the large proportion of the temperature-regenerated asphalt mixture with the M-1 warm-mix agent determined by the equal-volume method is about 10 ° C, and the temperature drop range of the mixed Sasobit warm-mix agent is about 18 ° C. According to the same volume method of forming warm recycled asphalt concrete has excellent high temperature performance, low temperature performance and water stability, all meet the regulatory requirements.
