石料碱值对沥青混合料水稳定性的影响

The Effect of Aggregate Alkali Number on Water Stability of Asphalt Mixtures

沥青与石料粘附性好坏直接影响着沥青混合料的耐久性．如果石料选择不当且不掺外加剂，这就很难得到稳定的沥青混合料，为此本文探讨了不同性质的石料对沥青混合料水稳定性的影响。

The adhesion of asphalt with aggregates affect the duration property of asphalt mixtures,if aggregates are very poor and not modified,it cant gain stabilited mixtures.So the paper researches on the effect of aggregate alkali number on water stability,at last,the aggregate alkali number with water stability standard of asphalt mixtures is put forward.
