| 摘 要： | 用弯曲梁流变仪、直接拉伸试验机对7种国内外油源沥青样品进行了低温抗裂性能的评价，从沥青的四组分、相对分子质量及其分布来分析其对沥青低温抗裂性能的影响，结果表明，沥青的相对分子质量分布宽，对沥青的低温抗裂性能有利。

| Abstract: | The low-temperature anti-cracking properties of 7 samples of foreign and domestic road asphalts were evaluated by Bending Beam Rheometer and Direct Tension Test. The effects of 4 chemical compositions, relative molecular and molecular weight distribution of the asphalts on their properties of low-temperature anti-cracking were studied. The results indicated that the wider the molecular weight distribution the better the property of low-temperature anti-cracking. |
