温拌沥青混合料抗水损坏性能试验研究

Experiment Research on Anti-water Damage Ability of Warm-mix Asphalt Mixtures

Evotherm DAT-H5及SAK两种温拌沥青混合料的抗水损坏性能试验结果表明,其TSR指标均刚刚满足规范要求。通过采用水泥或消石灰替换矿粉的方法,可以明显提高SAK温拌沥青混合料抗水损坏性能,但是对Evotherm温拌沥青混合料而言,情况却相反,应用时须根据实际情况正确选择提高温拌沥青混合料抗水损坏性能的方法。

Anti-water damage experiment results showed that TSR targets of both Evotherm DAT-H5 and SAK warm-mix asphalt are just to meet the regulatory requirements. Through replacing slag by cement or lime can significantly improve the anti-water damage ability of SAK warm-mix asphalt, however ,when it comes to Evotherm DAT-HS, the situation is the opposite. When used to the field, we should choose the right method according to different kinds of warm-mixtures to improve the anti-water damage ability of them.
