道路基层用粉煤灰作基层材料的试验研究

Experimental Study on the Fly Ash as the Base Material Applied to the Road Foundation

研究发现,改性粉煤灰、石灰和碎石混合料,具有早期抗压强度高、强度发展迅速的优点,并具有较强的抗冻融循环能力。

It was found that the modified material, which mainly consisted of fly ash, slaked lime and crushed stone, had the distinguish feature、compared with the control. The early strength of the modified material was high and its strength development was fast Moreover, its resistance to alternate freezing and throwing was strong.
