粉煤灰路堤的施工,与土路基基本相同,但由于粉煤灰材料的某些特点,在一些工艺参数和施工环节上有所区别。我们在沪嘉、莘松两条高速公路工程中修筑了粉煤灰路堤试验段,在试验路修筑过程中,结合现有的机械化施工条件进行了施工工艺的研究。这些研究结果对今后的粉煤灰路堤施工具有一定的指导意义和参考价值。现介绍如下:
Fly ash embankment construction, and soil subgrade basically the same, but due to some characteristics of fly ash materials, some of the process parameters and construction links are different. We built fly ash embankment test section in two projects of Shanghai Expressway and Xinsong Expressway. During construction of test road, the construction technology was studied in combination with the existing mechanized construction conditions. The results of these studies have certain guiding significance and reference value for fly ash embankment construction in the future. Now introduced as follows:
