集尘灰对沥青混合料水稳性的影响

Influence of Baghouse Dust on Water Stability of Asphalt Mixtures

过去对于集尘灰能否应用于拌制沥青混合料常发生争议。试验表明 :高塑性指数的集尘灰对沥青混合料的水稳性有明显影响 ,应限制使用 。

The application of baghouse dust to asphalt mixtures gives rise to much controversy. Tests show that baghouse dust with high plasticity index has an influence on the water stability of asphalt mixtures, so that we can not use it as a filler. However, the application of baghouse dust with low plasticity index is benefit to environment protection.
