摘要
为客观评价沥青混合料和易性大小,采用沥青混合料和易性试验仪对Sasobit温拌沥青混合料的和易性进行评价。先采用沥青砂浆对沥青混合料和易性试验仪的可行性进行研究。然后在不同温度和不同频率下测定Sasobit温拌沥青混合料的和易性,并同热拌沥青混合料进行对比分析,试验结果表明Sasobit温拌沥青混合料在降低30℃拌和温度的情况下,具有同热拌沥青混合料一致的和易性。
In order to evaluate the workability of asphalt mix objectively,the asphalt mix workability testing machine was adopted to evaluate the workability of Sasobit warm mix asphalt.At first,the feasibility of the machine with asphalt mortar was xtudied,and then testing the workability of Sasobit warm mix asphalt in different temperature and frequency was testad.The results were compared with that of hot mix asphalt.Rresults show that when the mixing temperature of Sasobit warm mix was reduced 30℃,the workability of Sasobit warm mix asphalt cau get the same result with HMA.
