| 摘 要： | 目前SMA沥青混合料的木质纤维素掺量（0．3％）均以经验确定，缺乏相关的试验依据，文章提出通过SMA沥青混合料路用性能试验以选择确定混合料的最佳纤维掺量。通过评价和分析不同纤维掺量SMA沥青混合料的各项路用性能，包括析漏、肯特堡飞散、抗水损害、高温稳定性能、低温稳定性能等试验，以确定推荐SMA沥青混合料的最佳纤维掺量。研究结果表明，SMA沥青混合料木质素纤维的最佳掺量为0．33％。

| Abstract: | The 0.3% Methyl Cellulose content in the SMA mixture is determined by the experience and lack of the lab data, and the article gives the laboratory research method for determining the Methyl Cellulose content in the SMA mixture, which is based on the mixture performance tests.Based on the result of evaluation the SMA mixture performance with different Methyl Cellulose content, which indudes the Binder Drainage test, Cantabro test, Water-induced Damage test, rutting test and low-temperature test, the optimal Methyl Cellulose content of SMA mixture is determined. The laboratory research shows that the optimal Methyl Cellulose content is 0.33 % different with empirical Methyl Cellulose content. |
