| 摘 要： | 文章针对寒冷地区气侯的特殊性,运用沥青混合料弯曲试验方法,分析了温度、公称最大粒径、油石比、沥青种类等因素对寒冷地区沥青混合料弯拉特性的影响及作用规律。研究结果表明：混合料油石比在6.0%～7.0%范围内取值较适宜;SBR改性沥青混合料低温性能优势显著;多年冻土地区路面设计应该重视-10℃下沥青混合料的弯曲特性,提高沥青混合料的低温性能。 |
| 关 键 词： | 寒冷地区 沥青混合料 弯拉特性 温度 油石比 分析 |

| Abstract: | According to the special climate type in cold area,the article uses asphalt mixture bending test to analyze the impact of temperature,nominal maximum size,aggregate ratio and asphalt types on the bending and stretch characteristic of asphalt mixture.The study result shows the more appropriate aggregate ratio is 6%～7%;SBR modified asphalt mix-ture has better performance under low temperature;When design roads for frozen earth area,the bending and stretch characteristics of asphalt mixture under-10℃ need to be paid more attention in order to improve its performance under low temperature. |
| Keywords: | Cold area Asphalt mixture Bend and stretch Temperature Aggregate ratio Analysis |
