摘要
针对酸性集料与沥青粘附性差、混合料水敏感性大的难题 ,根据配位键理论采用含铬外加剂处理酸性集料 ,显著提高沥青与酸性集料的粘附性。用强化的冻融劈裂试验评价混合料水损害 ,对比试验说明经过含铬外加剂处理后的酸性集料混合料劈裂强度比提高显著 ,长期抗水损害性能也较好。
Acidity aggregate has poor bond strength with asphalt and also produce the problem of mixture's serious water sensitivity. In this paper, acidity aggregate was treated with the additive including chromium to improve its bond strength greatly between asphalt and aggregate. A improved freeze-thaw split test was used to evaluate the mixture water sensitivity. The experiments indicated that mixture's split strength was improved when the mixture treated with chromium additive and also its long-term anti-stripping property was fine.
