【摘要】：针对热拌橡胶沥青混合料(HRMA)良好路用性能及高施工温度的特点,选用温拌剂LQ-1106,采用等体积法作为温拌橡胶沥青混合料(WRMA)压实效果评价指标,将与HRMA达到相同设计空隙率的温度视为最佳击实温度,并在最佳击实温度条件下选用SMA级配研究温拌橡胶沥青混合料高温稳定性、低温抗裂性以及水稳定性能。试验结果表明:WRMA压实温度较HRMA降低约30℃,高温性能、低温性能较热拌橡胶沥青混合料有一定提高,但水稳定性能略有下降。该试验结果可为温拌橡胶沥青混合料配合比设计和施工质量控制提供依据。
[Abstract]:In view of the good road performance and high construction temperature of hot mix rubber asphalt mixture (HRMA), the warm mix agent LQ-1106, was chosen as the evaluation index of (WRMA) compaction effect of warm rubber asphalt mixture by equal volume method. The optimum compaction temperature was considered to be the same as that of HRMA, and the SMA gradation was selected to study the high temperature stability, low temperature crack resistance and water stability of warm rubber asphalt mixture under the optimum compaction temperature. The results show that the compaction temperature of HRMA is about 30 鈩，
