我省自80年底开始在道路基层上应用粉煤灰,着重进行筑路性能的研究,并对粉煤灰路面基层早期强度的改善进行了探索;以置换石灰剂量的2％水泥量掺入,其早期强度可提高30～50％。目前我省采用粉煤灰铺筑道路基层约15公里。路面使用质量经历年观测良好,有的路段经过多年强度测定,回弹弯沉l_(0.2～0.4),强度高,稳定性好,能适应交通量日益增长的需要。
Since the end of 1980, our province has applied fly ash on the grassroots level, focused on the research of road performance, and explored the improvement of the early strength of fly ash roadbed. With 2% Its early strength can be increased by 30 ~ 50%. At present, our province uses fly ash to pave the road for about 15 km. Pavement use quality experience good years of observation, and some sections after years of strength determination, rebound deflection l_ (0.2 ~ 0.4), high strength, good stability, to adapt to the growing traffic needs.
