提高二灰碎石早期强度的室内及路用试验结果

The Summary and Observation of Improving Lime-Flyash-Aggregate Early Strength Test Road

本文在提高二灰碎石早期强度室内试验的基础上 ,采用NaOH、Na2 CO3作为早强剂修筑了 5 0 0米试验路。对试验路的观测研究表明 ,早强剂对提高二灰碎石早期强度效果明显 ,能缩短二灰碎石的成型时间和施工期限 。

Based on the testing results of lime-flyash-aggregate, NaOH, Na 2CO 3 are used as additives to construct test road 500m. Through studying and observing test road, its effect is very obviously to improve the early strength of lime-flyash- aggregate and the test is successful. The construction period can be shorten and the technique can be applied in highway construction.
