| 摘 要： | 掺加适当的添加剂,可以改善沥青混合料的水稳定性,但马歇尔试验的结果可能因此改变。本文以AC-13F型沥青混凝土为对象,在实验室试验的基础上,探讨消石灰、水泥、石灰 水泥等无机添加剂对沥青混合料马歇尔试验结果的影响。试验结果与分析表明,各种添加剂的掺入将使最佳沥青用量增加约0.4%;同时,不同添加剂对密度、稳定度、矿料间隙率和流值可有不同的影响。

| Abstract: | Proper additives can be used to improve the moisture susceptibility of asphalt mixture.However,results of Marshall test may be changed consequently.Laboratory tests are conducted on AC-13F asphalt concrete to investigate the influence of hydrated lime,Portland cement,and lime cement additives on Marshall test results.Results and analyses show that the use of the additives will increase the optimum asphalt content by about 0.4%.In addition,different additives may have different influences on density,stability value,voids in mineral aggregate and flow value of asphalt mixture. |

| Keywords: | asphalt mixture inorganic additive Marshall test optimum asphalt content |
