摘要:
基于表面自由能理论,采用接触角法测定2种沥青与4种集料的表面自由能参数,分别计算出各种沥青-集料体系的粘附功和剥落功,以表征沥青-集料体系的粘附性优劣;并采用冻融劈裂试验进行验证.结果表明:石灰岩集料与SK70改性沥青的粘附功最大,剥落功最小;花岗岩集料与SK基质沥青的粘附功最小,剥落功最大.此外,剥落功表征的沥青-集料体系的粘附性能与冻融劈裂试验表征的粘附性能基本一致;且沥青-集料体系的剥落功更能直观地定量评价沥青-集料体系的粘附性能.
Abstract:
Based on the surface energy theory, surface energy parameters of two kinds of asphalt and four kinds of aggregate were obtained by a static contact angle method, and the adhesive work and the exfoliated work of different asphalt-aggregate systems were calculated to determine whether the adhesion between different asphalt-aggregate systems was good or not. Meanwhile, a freeze-thaw splitting test was used for verification. The results suggest that in a modified asphalt-limestone system, it has the highest value of adhesive work and the lowest exfoliated work. As for the asphalt-granite system, the results are the opposite compared to the asphalt-limestone system. In addition, the adhesion between different asphalt-aggregate systems characterized by the exfoliated work is consistent with the results of the freeze-thaw splitting test; therefore, exfoliated work can characterize the adhesion between different asphalt-aggregate systems more intuitively and quantitatively.
