针对乳化沥青冷再生混合料早期磨耗问题,基于ASTM D7196-06扫刷试验方法,研究了密度、乳化沥青掺量、水泥掺量、养生时间对乳化沥青冷再生混合料早期磨耗性能的影响。结果表明,水泥剂量对早期磨耗性能影响不大;增加乳化沥青掺量,早期磨耗性能有小幅改善;密度对早期性能有较大影响;本研究所采用的乳化沥青混合料要获得足够早期磨耗性能,需要12h以上的养生时间;同时,ASTM D7196-06对于压实次数及养生时间的规定还需进一步论证。 According to the ASTM D7196-06 sweep test method, the effects of density, emulsified asphalt content, cement content and curing time on the early wear behavior of emulsified asphalt cold recycled mixture were studied. The results show that the cement dosage has little effect on the early wear performance. When the dosage of emulsified asphalt is increased, the early wear performance is slightly improved. The density has a great influence on the early performance. The emulsified asphalt mixture used in this study needs to get enough early wear performance , Need more than 12h health time; the same time, ASTM D7196-06 for compaction times and health requirements still need further proof.
